About
Lovely spot near Snowdon Ranger Path Car Park. It’s very short walk along a shingle path to the shore, also shingle. It’s very shallow to begin with so you need to wade out quite far tp swim. The water is very clear so easy to see some of the larger rocks to avoid
Location
Getting there
There is a car park off the A4085 Snowdon Rangers Path car park. It’s cost £3 for 4 hours. The shore is 2 min walk from there.

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.
