About
Man made lake. Fresh water. Very deep. At the recreation beach less deep. The lake is still an active sand win. Good place to safely train. When wind is strong enough there may be windsurfers and kites.
Location
Getting there
By car, bicycle there is a large parking. A bus between Wassenaar and Leiden stops at the entrance
Accessibility
From the beach is easy. There is a jetty at the other side (not preferable to use). Inside the allocated swimming area is undeep. Most experienced swimmers stay just outside the line.

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.
