Although the man-made Gaasperplas lies in a heavily populated area, this beautiful lake is still a perfect example of peace and tranquillity. The Gaasperplas recreation area consists of a large lake, several manicured gardens, children's playgrounds and plenty of lounge areas. The northern part was constructed in 1982 to host Floriade, the International Horticultural Exhibition. Only sail boats, row boats, windsurfers and fishermen can disrupt the peace here, as motorboats are prohibited. Over 165 acres of park land is available with broad lanes, unique vegetation, rose gardens and dune landscapes. You can easily spend a day in this area, but don't expect any flashy beach houses or food stalls, as in some of Amsterdam's other parks. You'll have to bring your own food for a pinic at the Gaasperplas. The swimming is great, but some people fear its great depth, which can reach over 35 metres. There's even a small nude beach on the northern side. Boats and canoes can also be rented and the park also hosts some great dance parties like Open Air and Gaasper Pleasure.
