Lake near Tan-y-Bwlch roughly 50m in length several access points including a gentle wade in point at the south end at the end of the wall. Deep enough for a proper swim. Squishy underfoot so shoes are reccomeded
Location
Getting there
Parking at the forestry off the b4410. Follow the path up the hill the head left into the wood to the lake roughly 15 min walk.

Frequently asked questions
Is this lake safe for swimming?
Check the Conditions tab for surface state and wind conditions. Review the Quality tab if this is a designated bathing water. Always read recent community reports for local advice.
How cold is the water?
Check the Temperature tab for the current estimate and 7-day trend. Lakes hold heat longer than rivers but can develop a thermocline. The water below the surface can be dramatically colder.
What should I bring?
A tow float for visibility (especially important where boats operate), warm layers for after, and consider a wetsuit in colder months. Check for designated swimming areas.
