Wild Swimming On Pen Yr Ole Wen, Eryri National Park (Snowdonia)

If you want a wild swim with a view, then they don’t get much better than the this spot on Pen Yr Ole Wen overlooking the mighty Tryfan in the Ogwen Valley. With a relatively short route up but with BIG views, its no surprise this is a go to of ours when were in the Ogwen Valley.

What to expect

You’ll leave the Ogwen valley and head up the quieter side of the mountains past Llyn Ogwen before you start the climb up Pen Yr Ole Wen. The path is quite tricky to follow in places and not always obvious but as long as you keep the river in your sight you can’t go too far wrong.

There may be times you have to cross calmer sections of the falls on stepping stones, so its not the easiest walk but the views back down the valley towards the lake and Tryfan are breathtaking.

Tips & what to bring

Good walking boots, always. Even in summer the path can be wet in places and you need solid footwear with good grip to cross the falls as the rocks here can be slippy. Be sure to also pack swimwear, a towel, swimming shoes, as well as extra layers and a hot drink for after your swim.

Eat & drink nearby

Betws Y Coed. Llanberis and Caernarfon are all within a 30 minute drive for post swim refreshments. There is also a little cafe at the visitor centre at the main car park in the Ogwen Valley.
