Close to the city center, De Oeverlanden has been a popular cruising area for men for decades. The city of Amsterdam tried several times to get rid of the men looking for sex with other men. This never worked, so finally the city decided to allow cruising in a designated area. Other parts of the area were developed with beaches and a restaurant. Signs at the entrances indicate (in pink) the cruising area.
During warm sunny days this area is full of naked men, so that is why I decided to list it here. So it has nothing to do with naturism, but you can be naked here. It is close to the motorway and airport. Easy to get here, but it is noisy.
It is possible to swim in the lake De Nieuwe Meer. After the Second World War, a lot of debris was dumped here. The bottom of the lake contains dangerous obstacles. So protect your feet well when you go swimming. The lake is very deep, so the water does not heat up too quickly in summer. But blue-green algae can develop here as well. So be careful.
