Wild Swimming in Eryri 

Wild swimming continues to grow in popularity as more people become aware of the remarkable benefits of cold water therapy on both physical and mental health. Physically, cold water immersion helps to boost circulation, strengthen the immune system and aid recovery from exercise and injury, it can even act as a form of pain relief. Mentally, the resulting natural endorphin rush creates a ‘feel good factor’ and when practised regularly can help control anxiety, stress and depression, as well as elevating energy levels. Pretty impressive.

Here in North Wales there are a plethora of swimming spots suitable for all abilities, from beginners looking to experience a quick, exhilarating dunk to serious open water swimmers. Eryri (Snowdonia) is full of scenic lakes, rivers and waterfalls which offer some of the most beautiful swimming locations in the UK.

Wild swimming might not immediately appeal to everyone, but it’s a great way to push yourself out of your comfort zone, it’s also great fun and, even better, it’s completely free. If you fancy giving it a try, then take a look at these magical wild swimming spots…

Llyn Padarn

Llyn Padarn is one of Eryri’s largest natural lakes and a popular spot for wild swimming. Surrounded by majestic mountains, including the famous Yr Wyddfa (Snowdon), its clear, cool waters offer a refreshing swim. There is a designated swimming area, making it a safe choice for families and less experienced swimmers.

Watkins Pools

This series of waterfalls and pools lies just off the Watkins Path, one of several routes up Yr Wyddfa, and makes a magical wild swim spot. Approx 30 mins walk from the car park this is a seriously beautiful spot, with crystal clear waters and shallower and deeper pools ideal for mixed abilities of dippers. To top it off, the views are just awesome. 

Llyn Dinas

Situated near Beddgelert, Llyn Dinas is an easily accessed swim spot. This picturesque, sheltered lake has clear waters and is surrounded by verdant landscape with stunning views of the surrounding hills. Popular with open water swimmers but quieter than some of the main hot spots. 

Nantcol Waterfalls 

Nancol Waterfalls near Llanbedr is a series of three pools ranging from shallow to deep; the deepest is a 15ft pool with an impressive waterfall backdrop. Set in a stunning wooded area Nantcol is great for paddling, jumping or a decent swim in the larger pool. 

The Afon Ddu

For those interested in river swimming, the Afon Ddu, near Betws-y-Coed, provides a series of freshwater pools and waterfalls. It’s a magical place for a dip, with clear pools surrounded by lush forest. The varying depth of the pools makes it suitable for different skill levels. Also a popular spot for gorge walking.

Ceunant Mawr / Llanberis Falls

Ceunant Mawr, also known as Llanberis Falls, is a cascading waterfall which plunges over 100ft in two stages to a huge pool at its base. This refreshing pool is just perfect for a dip or a paddle on a hot day but take care when the water levels are high. 

Rhaeadr Mawddach and Pistyll Cain

These two waterfalls are situated close together in Coed y Brenin Forest Park, near Dolegllau. Rhaeadr Mawddach is the smaller of the two but has a greater water flow, while nearby Pistyll Cain has a large deep plunge pool set among the ruins of a former goldmine. Care should also be taken at both these spots when the water levels are high. 

Tips for Wild Swimming in Eryri

Wild swimming can be great fun, but it’s essential to prioritise safety so make sure you stick to basic guidance. 

• Safety first: Always assess the conditions before taking the plunge, never jump or dive unless you’re sure there are no underwater hazards, be aware of the water temperature, currents and conditions and never swim alone. 
• Local knowledge: Be cautious when swimming in a new area and go with locals if you can. Facebook groups are a good place to connect with local dippers who can offer safety tips and advice on the best local swim spots.
• Be prepared: Mountain lakes and rivers can be very cold, even in summer, so consider wearing a wetsuit, or at the very least water shoes (which will also help protect your feet from any sharp rocks) and a hat. Make sure you have a towel, warm clothes and a flask of tea ready to help you warm up afterwards.
• Check access: Many swimming spots in North Wales and Snowdonia are accessible via hiking trails or short walks from nearby parking areas, however some areas may have restrictions or require permission to access so always check beforehand.

The Outdoor Swimming Society have lots of advice for anyone keen to give wild swimming a go, while Snowdonia National Park have a page dedicated to wild swimming tips, safety and suggested locations.

Wherever you choose to wild swim remember to respect the natural beauty of these areas and avoid disturbing wildlife or habitats by keeping to designated swimming areas where available, following any guidance and being mindful of leaving no trace.
