The 7 Best Wild Swimming Spots in the UK

Wild swimming has always been a popular pastime, especially for those who thrive in the outdoors and want an invigorating experience, given how cold many wild swimming spots tend to be. With several rivers, streams and lakes offering the best wild swimming experiences across the UK, you’ll be spoilt for choice. 

From magical pools hidden away in remote Scottish islands, to revered rivers known for their clean and safe water that makes them ideal for a dip, the UK is perfect for wild swimming. 

From vast mountain lakes to quaint tidal pools, here are 7 of the best wild swimming spots in the UK

7. Portreath Tidal Pool – Cornwall, England

Cornwall is widely known for its beautiful coast and pools, and one of the most picturesque and well-loved is the Portreath Tidal Pool. Somewhat hidden from the everyday swimming and beach spots, Portreath Tidal Pool is perfect for those who want a more laid-back and less crowded wild swimming experience. If you want to visit this pool, head to Portreath Beach and find the harbour wall. If you want this pool pretty much all to yourself, head down there in the winter, when the water is much colder and makes for a perfect refreshing icy plunge. 

6. Shimna River– Mourne Mountains, Northern Ireland

Northern Ireland’s Mourne Mountains are some of the most picturesque mountains in the UK, and they host a wide range of hidden and lesser known spots. While the Shimna River isn’t exactly a hidden gem, there are certain spots that are so picturesque that they look like something straight out of a fairytale. In Tollymore Park, which is known for its mythical and fairytale-like appearance, there are several popular wild swimming spots along the river, like Foley’s Bridge. No matter the time of year, these pools and sections of the river are perfect for wild swimming – cool off in the water during summer, take a daring dip in the winter, or enjoy the stunning colourful surroundings and milder water temperatures in the autumn.

5. Hampstead Heath Ponds – London, England

Hampstead Heath is one of London’s best-loved parks, and is known for its expanse of greenery and its ponds, some of which are popular bathing and swimming spots. Hampstead Heath’s Ponds are separated into men’s, women’s and mixed ponds, and are a popular year-round attraction for those who want to cool off during the summer or rejuvenate and refresh during colder times of year. Hampstead Heath Ponds are some of the most natural-feeling ponds, as along with you and your friends, you’ll also find several types of ducks and fish joining you for a swim too. 

4. Llyn Llydaw – Snowdonia National Park, Wales

Located near Wales’ highest mountain, Snowdon, Llyn Llydaw Lake is found along the Miners Track, which is a popular hiking route up the mountain. The lake is steeped in Arthurian legends, making it significant in Welsh mythology and folklore, which is perhaps part of the reason why this lake is such a popular visiting and swimming spot for hikers. The expansive lake is one of the UK’s most renowned wild swimming spots, and perfect if you want to swim in a secluded area away from busy crowds. Take a dip in the lake after a long hike up Miners Track, but brace yourself as the lake is notoriously cold. 

3. Ullswater Lake – Lake District, England

Another of the UK’s most beautiful national parks, and perhaps the most picturesque, is the Lake District. Aptly named, thanks to its many lakes and waterways, the Lake District is one of the best wild swimming places in the UK, so it can be hard to choose the best lake to dip in. Ullswater is one of the most picturesque and popular lakes, but is known for its particularly cold waters, so it’s advisable to wear a wetsuit to protect you from the cold if you do decide to swim here or intend to spend a long time in the water. Be wary that certain parts of this lake are deep too, so it’s recommended to stay near the shoreline if you’re not a confident swimmer. 

2. Blue Lagoon – Pembrokeshire, Wales

One of the more curious swimming spots, the Blue Lagoon in Abereiddy, Pembrokeshire isn’t quite as famous as its Iceland counterpart, but offers a unique swimming experience away from the traditional lakes or rivers. Formed out of an old quarry site, the Blue Lagoon is made from mineral-rich seawater with an aqua-hue, thanks to the slate in the quarry. Come rain or shine, the Blue Lagoon is perfect for a swim, paddle or dive, but prepared for the water temperature to drop significantly in the winter months. 

1. Fairy Pools – Isle of Skye, Scotland

We’ve put this at number one thanks to its beauty, cultural significance and the legends associated with it. Located on the remote Isle of Skye, true nature lovers and explorers will likely know a thing or two about the fairy pools, but first-time visitors to Scotland will likely be unaware of its existence, or its reputation. Known for its especially cold and clear water, the fairy pools are perfect for a refreshing and invigorating swim, and are so named thanks to Scottish myths and folklore that surround the pools. One of the best places for a wild swim, it’s safe to say Fairy Pools deserve their spot at the top of our list.
