Generally known as 'Camping Amsterdamse Bos', this campsite is located in the large park / man-made forest Amsterdamse Bos. Despite the name, it is actually located in the municipality of Amstelveen, which could be relevant for navigating the address of the campsite.
Practically speaking, the campsite is rather far away from the center of Amsterdam, but there are various ways of getting there by public transport. Cycling would be about 13 km to Dam Square, about 9 or 10 km to the Vondelpark.
The site is not only for tents, but also for RV's. There is a variety of hiker's cabin chalets (sold under the name 'hostel'). From November through March the chalets can also be booked for temporary housing.
