If you’re coming to Amsterdam in Summer, you should definitely visit De Oeverlanden park. Either if it’s sunny to relax naked on the open field and take a nap in the middle of your visit. Or to enjoy one of the world’s unique official gay cruising area. It’s actually official as authorities have dedicated a part of the park to cruising (they even indicate with some signs where you can cruise). And cruising is strictly limited to this area. It’s mostly gay guys coming here, but you occasionally have some straight people too. The area works both at day and at night. In summer you may also find a bus where you can do some free STD tests. Always good to know.
