Few coastlines in Europe can match the Costa Blanca for sheer variety. Stretching for more than 200 kilometres along Spain’s southeastern Mediterranean shore, this sun-drenched strip of Alicante province delivers everything a beach lover could want — from vast, golden sandy shores flanked by promenades and beach bars, to hidden rocky calas where turquoise water laps against limestone cliffs with barely another soul in sight.
What makes the best beaches on the Costa Blanca stand apart isn’t just the reliably excellent weather (over 300 days of sunshine a year) or the consistently warm, clear sea. It’s the extraordinary range. Whether you’re after a lively resort beach with every facility imaginable, a quiet family cove with shallow water and a chiringuito nearby, or a remote natural beach backed by pine forest, the Costa Blanca coastline delivers.
If you’re planning a broader trip to the region, the Costa Blanca Travel Guide – The Ultimate Resource covers everything you need to know beyond the beach — from inland villages and local cuisine to transport, accommodation and cultural highlights. This guide focuses specifically on the beaches: what’s out there, where to find it, and how to make the most of every stretch of coastline.

Overview: The Costa Blanca Coastline
Understanding the Costa Blanca as a whole helps explain why its beaches feel so varied. The coastline is broadly split into two distinct characters — northern and southern — and the difference is more dramatic than many visitors expect.
The northern Costa Blanca, stretching roughly from Denia down through Jávea, Calpe, Altea and towards Benidorm, is greener, more rugged and more dramatic. The Montgó massif rises above Denia and Jávea, and the coastline here is characterised by rocky promontories, clear-water calas and smaller sandy coves tucked between headlands. This is the Costa Blanca of postcards and painters — visually striking, with water clarity that rivals the best of the Mediterranean.
The southern Costa Blanca, running from Alicante down through Santa Pola, Guardamar del Segura, Torrevieja and beyond into the Vega Baja, is flatter, broader and defined by longer stretches of pale sand. Backed in places by dunes and salt lagoons, this stretch trades drama for space — ideal for families, walkers, and anyone who wants kilometre after kilometre of beach without the crowds.
Key resort towns each have their own beach personality. Denia and Jávea attract independent travellers and second-home owners. Benidorm is unashamedly a resort powerhouse with two outstanding urban beaches. Alicante blends city life with accessible swimming. Torrevieja, at the southern end, offers quieter, sun-bleached shores that many visitors overlook entirely.
The beaches here span everything from Blue Flag certified urban shores to off-grid nudist beaches, from family-friendly shallows to dramatic rocky calas. The sections below work through each category in detail.
Blue Flag Beaches on the Costa Blanca
The Blue Flag is awarded annually by the Foundation for Environmental Education to beaches that meet strict standards across four categories: water quality, environmental management, safety and services, and environmental education. For travellers, a Blue Flag beach is a reliable signal that the water is clean, the facilities are well maintained, and there are trained lifeguards on duty during the swimming season.
Spain consistently ranks among the top Blue Flag countries in the world, and Alicante province — which covers the Costa Blanca — contributes significantly to that total. The region holds one of the highest concentrations of Blue Flag beaches anywhere in Spain, reflecting both the natural water quality of the Mediterranean here and the investment local councils make in beach infrastructure.
Notable Blue Flag holders along the Costa Blanca include Playa de San Juan in Alicante, the long arc of Playa de las Marinas in Denia, Playa de la Fossa in Calpe, and both of Benidorm’s main beaches. Many smaller calas and resort beaches also carry the award in a given year, though certification can change annually.
For a full rundown of certified shores and what to expect at each, the dedicated guide to Best Blue Flag Beaches on the Costa Blanca is the most thorough resource available.
Best Beaches Near Alicante
Alicante is one of the few cities in Spain where the beach is genuinely part of the urban fabric. The city’s main swimming beach, Playa del Postiguet, sits directly below the castle of Santa Bárbara — you can take a lift from the rock face down to the shore — and is backed by a palm-lined promenade. It’s compact and popular with city residents, which means it fills up quickly in summer, but it’s kept in excellent condition and is easy to reach on foot from the old town.
Further north along the coast, Playa de San Juan is an entirely different proposition: a four-kilometre stretch of wide, pale sand with calmer water, excellent facilities and a more relaxed pace. It’s served by tram from the city centre and is the beach most Alicante locals choose when they want a proper day at the sea. South of the city, beaches at Arenales del Sol and El Carabassi have a wilder, less developed character, backed by dunes and with fewer crowds even at the height of summer.
Alicante rewards beach travellers who take the time to explore a little beyond the obvious. For everything you need to plan a beach day in and around the provincial capital, the guide to Best Beaches Near Alicante covers each option in depth.
Benidorm’s Famous Beaches
Benidorm divides opinion as a resort, but on the subject of its beaches, the argument is harder to sustain. Whatever your view of the tower blocks and stag parties, the two beaches that frame the resort’s headland are genuinely outstanding — long, wide, clean and well-managed, with water quality that consistently earns Blue Flag status.
Playa de Levante occupies the eastern arc of the bay. It’s the livelier of the two — more densely packed in summer, with a busy promenade, abundant facilities and a constant buzz of activity. It faces northeast, which means it catches the morning sun particularly well and remains sheltered from the prevailing afternoon winds.
Playa de Poniente stretches west from the headland and has a markedly different atmosphere. It’s broader, slightly quieter and has a longer promenade that gradually shades into more residential areas of the town. Sunsets from the Poniente side are spectacular, and the beach retains a more relaxed character even at peak season.
The dedicated guide to Best Beaches in Benidorm sets out the full picture for first-time visitors to the resort. For a close look at each individual shore, the in-depth guides to Playa de Levante Benidorm and Playa de Poniente Benidorm cover everything from facilities and parking to the best spots to set up for the day.
Hidden and Secret Beaches of the Costa Blanca
The Costa Blanca’s most famous beaches attract the crowds — which is reason enough to go looking for alternatives. Fortunately, the coastline between Denia and Alicante is riddled with coves, inlets and small beaches that most package tourists never see, and many that don’t appear in mainstream travel guides.
The northern stretch is the most rewarding hunting ground. The rocky coastline between Jávea and Calpe hides numerous small calas accessible only on foot or by boat. Some require a scramble down a cliff path, others a short kayak from a nearby bay. The reward is invariably the same: calm, gin-clear water, a handful of sunbathers who’ve made the effort, and the particular satisfaction of a beach earned rather than handed to you.
Even in the more developed areas, lesser-known spots persist. A rocky path beyond a car park, a beach accessible only at low tide, a cala tucked behind a restaurant that most diners don’t notice — the Costa Blanca rewards curiosity. The key is knowing where to look.
For a properly curated list of the region’s most secluded spots, the guide to Hidden and Secret Beaches on the Costa Blanca is the place to start — with practical access information for each.
Rocky Cove Beaches (Calas) – A Costa Blanca Speciality
A cala — the Spanish word for a small, enclosed rocky cove — is one of the defining beach experiences on the Costa Blanca. Unlike the broad sandy stretches that dominate the south, calas are intimate, sheltered, and often extraordinarily beautiful. They tend to have pebble or rocky floors, sometimes a narrow strip of coarse sand, and water that achieves shades of blue-green that seem almost implausibly vivid.
The appeal is partly aesthetic and partly practical. Because calas are harder to access — often requiring a path, steps or a short boat ride — they attract fewer people, and the water quality in them tends to be exceptional. Snorkelling in a cala is an entirely different experience from swimming off a busy urban beach.
Two calas in particular stand out as among the very best on the entire coastline. Playa de la Granadella, south of Jávea, is a wide, sheltered cove backed by cliffs and pine forest, with some of the clearest water on the Costa Blanca — the full guide to Playa de la Granadella explains what to expect and how best to visit. Further north, Cala del Moraig near Benitatxell is a dramatic limestone cove with snorkelling among sea caves and a famous underwater arch — the detailed Cala del Moraig guide covers access, facilities and the best times to arrive.
For a broader exploration of this beach type across the region, the dedicated roundup of Rocky Cove Beaches (Calas) on the Costa Blanca brings together the best examples from across the entire coastline.
Best Beaches for Families on the Costa Blanca
The Costa Blanca has built a strong reputation as a family holiday destination, and the beaches play a significant part in that. The best family beaches share a set of practical qualities: shallow, gently shelving water that’s safe for small children; trained lifeguards on duty during the summer season; easy access with good parking nearby; and facilities like toilets, showers, sunbed hire and a beach bar or café within easy reach.
The southern Costa Blanca tends to win on these criteria. Beaches like Playa de San Juan near Alicante, Playa de las Marinas in Denia and La Mata near Torrevieja offer long, flat stretches of sand with calm water and well-developed infrastructure. Benidorm’s Poniente beach is also an excellent family choice — broad enough that space is rarely a problem even in August, and with excellent facilities throughout.
Calm, shallow bays around Calpe and Moraira work particularly well for families with very young children, offering natural protection from waves and easy access.
The guide to Best Beaches for Families on the Costa Blanca brings together the top picks with practical information on facilities, lifeguard cover and access at each location.
Nudist Beaches on the Costa Blanca
Spain has a relaxed and long-established naturist culture, and the Costa Blanca is no exception. Several beaches along the coastline are either officially designated as nudist areas or have well-established naturist sections that operate without any fuss or legal ambiguity. For visitors who prefer naturist bathing, this is a destination with genuinely good options.
The southern Costa Blanca has the greatest concentration of recognised nudist beaches, with areas around Guardamar del Segura, the Parque Natural de las Salinas de Santa Pola, and stretches near Torrevieja offering established naturist bathing. In the north, certain quieter calas and more remote coves have a long tradition of clothing-optional swimming, even where there’s no official designation.
Attitudes on Spanish beaches are generally relaxed and non-judgmental. Naturist areas are typically well indicated, and mixed-use beaches (where one section is clothing-optional and the rest is not) are well understood by regular visitors.
For a practical guide to where, when and what to expect, the dedicated page covering Best Nudist Beaches on the Costa Blanca has the full picture.
Northern Costa Blanca Highlights: Denia and Beyond
Denia anchors the northern end of the Costa Blanca and is one of the region’s most attractive towns in its own right — a working port, a castle, a lively market and a dining culture built around excellent local seafood. Its beaches match its character: well looked after, varied in type, and drawing a mix of Spanish families and European visitors who return year after year.
The town’s beach zone divides into two main areas. To the north of the port, the Las Marinas coastline stretches for several kilometres of broad, sandy shore backed by low-lying dunes and holiday developments. This is Denia’s main family beach zone — long enough that it never feels truly overcrowded, with consistent Blue Flag status, good facilities and calm, shallow water that makes it one of the most accessible beaches in the northern Costa Blanca.
To the south of the port, the coast shifts character entirely. The Las Rotas area is rocky and rugged, with a series of small calas and natural platforms used for snorkelling and diving. The water here is some of the clearest in Denia’s immediate surroundings, and the area attracts a different crowd — divers, snorkellers, and visitors after something quieter and more natural than a sandy resort beach.
Beyond Denia, the coastline continues north towards the Montgó headland and the start of Jávea’s territory — one of the most scenically dramatic stretches of the entire Costa Blanca, where limestone cliffs drop directly into deep, transparent water.
For a full breakdown of Denia’s main sandy stretch, the Playa de Las Marinas Denia guide covers access, facilities, the best sections of beach to target, and practical tips for making the most of a day there.
Southern Costa Blanca: La Mata and the Torrevieja Coast
The southern Costa Blanca rarely makes the headlines in the way that Benidorm or Jávea do, but for many visitors — particularly those who’ve done the busier northern resorts and want something different — this stretch of coastline is a revelation. Flatter, quieter and more open than the north, it trades visual drama for a kind of expansive, sun bleached calm that suits long, unhurried days by the sea.
The town of Torrevieja is the main hub of this southern stretch. It sits between two salt lagoons — both protected natural areas — and its beaches benefit from consistently clean, shallow water with a gentler character than the more exposed northern shores. The town has invested heavily in its beach infrastructure in recent years, and the results show.
La Mata, a few kilometres north of Torrevieja, is one of the standout beaches on this part of the coast. A long, wide strip of pale sand backed by a natural park, it manages to feel genuinely open and unspoiled even in high summer — partly because of its length, and partly because the dune system behind it discourages the dense development found elsewhere. It’s particularly popular with Spanish visitors and with the large Northern European communities who have made this part of the Costa Blanca their home.
The full La Mata Beach Guide sets out everything you need to know — from the best access points and parking options to the facilities available and the quietest sections of beach to aim for.
Practical Tips for Visiting Costa Blanca Beaches
Best Time of Year to Visit
The Costa Blanca’s beach season runs broadly from May to October, but there’s considerable variation within that window. June and September are widely regarded as the best months for beach holidays — the sea is warm, the weather is reliably sunny, the facilities are fully open, and the beaches are noticeably less crowded than in July and August.
July and August are the peak summer months. The beaches are at their most vibrant but also their most congested, particularly in Benidorm, Alicante and the established resort areas. Prices for accommodation and flights reflect the demand. If you’re visiting in peak season, aim to arrive at the beach early — by mid-morning in August, the most popular beaches are already busy, and sunbed availability becomes competitive.
October can be wonderful — warm enough to swim comfortably in the earlier weeks of the month, with noticeably thinner crowds and a more relaxed pace. Many beach bars remain open through October, though some start winding down from mid-month onwards.
What to Bring and What to Expect
Most established beaches on the Costa Blanca are well equipped. Sunbed and parasol hire is almost universal on the major beaches, with rental typically costing between €6 and €15 per day for a set. Shower and toilet facilities are standard on Blue Flag beaches. Beach bars — chiringuitos — range from simple kiosks selling cold drinks and sandwiches to full-service restaurants with grilled fish and paella.
Bring reef shoes or water shoes if you’re planning to visit rocky calas — the limestone underfoot can be sharp, and entry into the water is often over rocks rather than sand. Snorkelling equipment is worth packing for the northern calas, where the water visibility regularly exceeds ten metres.
Beach Etiquette in Spain
Spanish beach culture is relaxed but has its own unwritten rules. Leaving litter is genuinely frowned upon — there are bins on all managed beaches, and the standards of tidiness on Blue Flag beaches are taken seriously by both authorities and regular visitors. Smoking is restricted or prohibited on many beaches in Alicante province; look for signage at the beach entrance.
Reserving sunbeds with towels and then disappearing for hours is tolerated but not universally popular. On the busiest beaches in August, it’s courteous to make use of your space or free it up for others.
Water Quality and Safety
Water quality along the Costa Blanca is generally excellent. The Mediterranean here is calm and relatively sheltered, and strong rip currents are uncommon on the main resort beaches. Yellow flags indicate caution (usually due to moderate waves or wind), and red flags mean bathing is prohibited — both should be taken seriously.
Jellyfish (medusas) can appear in some years, particularly in late summer when warmer water temperatures draw them closer to shore. Local beach staff and the Red Cross lifeguard posts will typically have information and basic treatment on hand if needed.
Accessibility
Accessibility on Costa Blanca beaches has improved considerably in recent years. Many of the principal resort beaches now offer beach wheelchairs (sillas anfibias) for loan free of charge, along with boardwalks across the sand and adapted shower facilities. Beaches in Benidorm, Alicante and Denia are generally the best equipped for visitors with mobility requirements. It’s worth contacting the local tourist office in advance to confirm current provision, as services can vary between municipalities.
Conclusion
The Costa Blanca coastline is one of the most rewarding beach destinations in Europe — not because of any single standout location, but because of the sheer breadth of what’s available along its length. From the dramatic limestone calas of the north to the wide, open shores of the south, from lively resort beaches with every facility imaginable to secluded coves that reward a little effort to reach, the best beaches on the Costa Blanca genuinely offer something for every kind of traveller.
This guide is designed as a starting point — an overview of the full landscape, structured to help you find what you’re actually looking for rather than defaulting to the most obvious options. Each section connects to a deeper, more detailed resource for that beach type or specific location. Whether you’re planning a first visit to the region or returning with a better sense of what you want, the Costa Blanca’s coastline has more to offer than most visitors ever get around to discovering.
Start exploring, plan well, and the sea will take care of the rest.
