Whether you’re looking for a calm sea swim, a dramatic quarry dip, or a refreshing river plunge, Cornwall has it all.
In this guide, we’ll take you through some of the best wild swimming spots in Cornwall, along with essential safety tips to help you enjoy the water responsibly.
Coastal Wild Swimming Spots
Gylly Beach & Castle Beach, Falmouth
Gyllyngvase Beach, or Gylly as it’s known locally, is one of the most popular and accessible beaches in Falmouth. The sheltered bay provides calm and clear waters, making it ideal for swimmers of all abilities. With the blue flag status, it’s a clean and safe environment, offering easy access to amenities like showers, toilets, and a beachfront café. The gently sloping shore means swimmers can ease into the water gradually, making it great for those new to sea swimming. Nearby Castle Beach offers a different experience, with its rock pools, sheltered coves, and fascinating marine life. Both beaches are fantastic for an early morning dip or a sunset swim, with stunning views of the bay. The area is also a watersports hub, making it an excellent spot for paddleboarding and occasionally surfing, alongside swimming.
Nanjizal Beach (Song of the Sea Cave)
Nanjizal Beach, often regarded as one of Cornwall’s best-kept secrets, offers a wild swimming experience like no other. Located near Land’s End, it requires a moderate walk along the rugged coastal path, but the journey is worth it. The beach is home to the iconic Song of the Sea Cave, a narrow rock archway that allows beams of light to shine through, illuminating the turquoise waters below. The crystal-clear water and secluded setting make it a magical place for a swim, particularly at high tide when the rock pools fill up. Unlike more tourist-heavy beaches, Nanjizal remains largely untouched, providing an unspoiled and peaceful environment. The dramatic cliffs and unique rock formations create a backdrop that feels almost otherworldly. However, as there are no facilities nearby, it’s best to come prepared with water, snacks, and appropriate footwear for the walk.
Portheras Cove, West Cornwall
Nestled between rugged cliffs on the north coast, Portheras Cove is a hidden gem known for its crystal-clear waters and unspoiled sands. This secluded cove offers a serene and peaceful atmosphere, away from the more crowded tourist beaches. The surrounding cliffs provide shelter from the wind, making the water generally calm, though it’s always wise to check the conditions before swimming. Portheras is a favourite among local wild swimmers, and its golden sands make it a wonderful place to relax after a refreshing dip. Seals are often spotted nearby, so it’s important to be respectful of the wildlife. The cove is accessed via a short coastal path walk, adding to the sense of discovery. There are no immediate facilities, so bring everything you need for the day. Whether you’re looking for a refreshing morning swim or a peaceful afternoon in the sun, Portheras is a fantastic choice.
Prussia Cove
Prussia Cove is a wild swimmer’s dream, offering a mix of rocky inlets, sheltered waters, and a fascinating smuggling history. Located on Cornwall’s south coast, this picturesque cove is made up of a series of smaller beaches, each with its own unique charm. The calm, clear waters are perfect for long-distance sea swimming, while the surrounding cliffs provide a dramatic backdrop. The cove is steeped in history, once home to the notorious smuggler John Carter, also known as the “King of Prussia.” This sense of mystery and adventure adds to the allure of the location. While the area remains largely untouched by tourism, it does require a bit of a trek to reach. There are no nearby facilities, so it’s recommended to come fully prepared. The beauty of Prussia Cove lies in its tranquillity and seclusion, making it a perfect spot for those looking to escape the crowds.
Kynance Cove
Kynance Cove is arguably one of Cornwall’s most breathtaking swimming locations. Famous for its white sands, turquoise waters, and striking serpentine rock formations, it feels like something straight out of a postcard. Located on the Lizard Peninsula, Kynance is a popular destination, so it’s best to visit early in the morning or late in the afternoon to avoid crowds. The waters here are exceptionally clear, making it a prime spot for snorkelling and exploring the underwater world. The dramatic tide changes reveal hidden caves and rock pools, which can be fun to explore. However, swimmers should be aware that the currents can be strong, so it’s best suited for confident sea swimmers. A small café sits above the cove, offering refreshments and stunning panoramic views. Whether you’re in for a quick dip or a full-day adventure, Kynance Cove is a must-visit for wild swimming enthusiasts.

Tidal Pools & Natural Rock Pools
Chapel Rock Pool, Perranporth
Chapel Rock Pool is a natural seawater pool located on the popular Perranporth Beach. The pool fills at high tide and offers a safe and enclosed environment for swimmers of all ages at low tide. The surrounding beach provides a long, sandy stretch, making it a great spot for families and those looking to combine swimming with a beach day. The nearby surfing scene adds to the vibrant atmosphere, and the town of Perranporth has plenty of cafés and amenities close by.
Bude Sea Pool
Bude Sea Pool is a semi-natural tidal swimming pool, providing a sheltered and safe swimming experience. Situated at Summerleaze Beach, the pool was originally built in the 1930s and is maintained by a local charity. The pool allows swimmers to enjoy the benefits of seawater swimming while avoiding strong waves and currents. It’s a great spot for all abilities, with a gradual entry making it accessible to beginners. The backdrop of Bude’s dramatic coastline makes it a favourite among locals and visitors alike.
Mousehole Rock Pool
Nestled in the picturesque fishing village of Mousehole, this hidden tidal pool offers a truly tranquil swimming experience. The pool is formed naturally, providing calm and sheltered waters perfect for those looking for a gentle dip. Surrounded by stunning sea views and charming granite cottages, Mousehole Rock Pool is an ideal location for swimmers who prefer a quieter, more intimate setting away from the busier beaches. At high tide, the pool is refilled with fresh seawater, creating a clean and refreshing place to swim. The surrounding village also offers quaint cafés and traditional Cornish pubs, making it the perfect spot for a post-swim treat. Due to its size and location, it is best enjoyed during off-peak times, allowing swimmers to fully soak in the peaceful ambiance.
Treyarnon Bay Tidal Pool
Treyarnon Bay’s tidal pool is a stunning, naturally-formed rock pool, carved into the rugged coastline. This secluded saltwater pool offers a safe and enclosed environment for wild swimmers while still maintaining a natural feel. Located on the north coast of Cornwall, this pool is a favorite among locals and visitors alike. The clear, deep water is ideal for those who enjoy a cool, refreshing swim, especially on a warm summer’s day. The surrounding rock formations provide a unique landscape, perfect for sunbathing or a post-swim picnic. At low tide, the pool remains accessible, but at high tide, it blends seamlessly with the sea, giving swimmers an exhilarating experience as the waves crash over the rocks. If you’re visiting in the evening, the sunsets over the Atlantic Ocean are truly breathtaking.
Polperro Tidal Pool
Hidden within the quaint fishing village of Polperro, this lesser-known tidal pool is perfect for those seeking a peaceful and undisturbed swim. Unlike some of the more popular wild swimming locations, Polperro Tidal Pool retains a quiet charm, allowing visitors to truly connect with nature. The pool is replenished with fresh seawater at high tide, ensuring clean and refreshing conditions for swimmers. The sheltered nature of the pool makes it particularly appealing for those looking for a more gentle and relaxing swim. The surrounding rocky outcrops provide natural seating areas, where swimmers can relax and take in the idyllic coastal views. The picturesque village of Polperro is also just a short walk away, offering plenty of options for a post-swim Cornish pasty or afternoon tea.
Freshwater Wild Swimming Spots
St Nectan’s Glen, Tintagel
One of Cornwall’s most magical and enchanting wild swimming spots, St Nectan’s Glen is a hidden woodland paradise featuring a breathtaking waterfall plunging into a crystal-clear pool. This sacred site has long been associated with legend and folklore, adding to its mystical charm. The lush green surroundings and moss-covered rocks create an almost fairy-tale-like setting, making it a unique place for a refreshing dip. The water is cool year-round, but the beauty and serenity of the location make it well worth the visit. Many visitors choose to meditate or practice mindfulness in the area, as the calming sound of cascading water enhances the tranquil atmosphere. Access to the site involves a scenic woodland walk, making the journey just as special as the destination. Be sure to bring water shoes, as the rocky bottom can be slippery.
Golitha Falls, River Fowey
Golitha Falls is a stunning series of waterfalls and deep pools set in the heart of ancient oak woodlands along the River Fowey. The fast-flowing waters create a dramatic and picturesque setting, attracting both wild swimmers and nature enthusiasts. The river’s fresh, clear water makes for an exhilarating swim, though care should be taken as the currents can be strong, particularly after heavy rainfall. The surrounding woodland offers plenty of secluded spots to relax, making it a great place to spend a full day exploring. Many swimmers enjoy dipping into the calmer sections of the river, while others prefer the more invigorating experience of swimming beneath the falls. Golitha Falls is also rich in wildlife, so keep an eye out for kingfishers, otters, and other native species. The nearby walking trails provide excellent opportunities to combine a wild swim with a scenic hike.
Goldiggins Quarry, Bodmin Moor
Goldiggins Quarry is a spectacular wild swimming spot, tucked away in the remote and rugged landscape of Bodmin Moor. This abandoned quarry has since filled with rainwater, forming a deep, crystal-clear pool surrounded by striking granite cliffs. The dramatic setting makes it a favorite among those looking for an adventurous swim, with plenty of spots for cliff jumping and diving (for those who are experienced and confident in the water). The deep, cool waters provide an exhilarating experience, especially in the height of summer when Cornwall’s beaches can get crowded. Due to its remote location, this wild swimming spot remains relatively undiscovered, making it perfect for those looking for a more private dip. The surrounding moorland is perfect for a post-swim walk, offering sweeping views of Cornwall’s rugged countryside. Just be sure to bring sturdy footwear, as the path to the quarry can be uneven and rocky.
