Best places for wild swimming in Eryri | Snowdonia!
Here then are my favourite spots for wild swimming - let me know yours in the comments below!
Llyn Geirionydd
This lake is the nearest location to our B&B for wild swimming and it is a serene and picturesque location where wild swimming and other watersports are permitted.
You will find Llyn Geirionydd just above the village of Trefriw, near Betws-y-Coed.
A tarmac road hugs the western shore of the lake from which there are various access points, and at the end there is a car park with toilets and a ‘launch’ platform.
Bhoys in the water mark a useful wild swimming course!
We love it there as the still waters of Llyn Geirionydd reflect the changing seasons in the surrounding forests, with vibrant hues in spring and summer giving way to a kaleidoscope of autumnal colors.

Llyn Padarn
One of the most popular wild and open water swimming spots in Eryri | Snowdonia is Llyn Padarn, a glacially formed lake nestled amidst breathtaking scenery.
With its clear, emerald waters and the majestic backdrop of Yr Wyddfa | Snowdon, Llyn Padarn provides the perfect setting for a refreshing swim, and is also a great place for stand-up paddle boarding (SUP)!
The lake offers various entry points along the southern shoreline, making it easily accessible for swimmers of all abilities.
After a swim, you can bask in the sun on the pebbled shores or explore the nearby woodland trails.
Llanberis is a pleasant village also on Llyn Padarn and you will find there shops and cafes.

Llyn Gwynant and Llyn Dinas
Llyn Gwynant, nestled in the heart of Eryri | Snowdonia, near Beddgelert, is another gem for wild swimmers - the tranquil waters of this lake are ideal for leisurely swims and peaceful relaxation.
Surrounded by lush greenery and overlooked by the towering peak of Yr Wyddfa | Snowdon itself, Llyn Gwynant provides a serene and rejuvenating wild swimming experience.
You can spend the day swimming, picnicking, or simply soaking in the natural splendor of this idyllic location.
There are a few parking spots and access points at various points on the A498 road which goes along the eastern shore of the lake, with further parking (pre-booking only) at Llyn Gwynant campsite.
Nearby Llyn Dinas is another lake where wild swimming is permitted - there are some ‘beach’ areas at the southern end where you can enter the water, but I have found it to be a little reedy in places!
Beddgelert is close to both lakes and is a very scenic Welsh village with shops, cafes and restaurants.
The Fairy Glen
Situated just outside the pretty alpine village of Betws-y-Coed, the Fairy Glen is another fantastic location in Eryri | Snowdonia for wild swimming.
This picturesque, narrow gorge surrounded by trees is suitable for river swimming, with some large rocks to sit on.
It really is a magical place that will leave you invigorated and inspired!
(NB: access to The Fairy Glen is via private land and a small charge is applicable - cash only. The entrance has a small sign on the A470, just south of Betws-y-Coed.
You can reach it on foot from Betws-y-Coed by walking on the forest back road past Betws Motors - approx. 2 miles)
Llynnau Mymbyr
These two lakes (in reality it is one!) lie just beyond Capel Curig not far from Betws-y-Coed, and are a wonderful place to swim due to the expansive views of the Yr Wyddfa | Snowdon horseshoe mountain range.
You can park in the lay-by just after the Plas-y-Brenin outdoor centre, then walk down to the lake and go over the bridge to access a small ‘beach’ where you can access the water.
Wild swimming in Eryri | Snowdonia doesn’t really get much better when it comes to the awe-inspiring views all around you!

Safety and Considerations
Whilst wild swimming in Eryri | Snowdonia offers a unique and immersive experience in nature, it is essential to prioritise safety.
Always assess the potential risks of swimming in natural bodies of water and always be mindful of factors such as water temperature, currents, and hidden hazards.
Familiarise yourself with the area - especially if it is new to you - and ensure you have appropriate swimwear and gear such as swimming shoes and a float.
Once ready, acclimatise first to avoid ‘cold water shock’ by slowly entering the water, and have some warm clothes or a dry robe ready for when you exit the water!
Embrace the adventure!
Hopefully this will give you ideas and inspiration for your wild swimming adventure in Eryri | Snowdonia.
