Het Twiske is a large recreational area north of Amsterdam.

The official naturist beach, named Baaiegatstrand, is situated on a small island. There are toilets and drinking water. It is easy to get here by bike or car from Amsterdam.
It is mostly mixed naturists in this nice and quiet area. And a concentration of gays in the (small) west part of the island.
The water is good for a swim.
Cruising is almost impossible on this island. Some guys walk about 20 minutes to the north east. There is an island where you only find men...
