The Netherlands is hardly known for its hot summers, but when the mercury does rise for a few days or perhaps even a week, you can forsake the heat and the stagnant canals of the city centre and visit the De Oeverlanden Nature Reserve. Over 40 species of birds call this small piece of wilderness home, which is great for ornithologists, but the reserve also borders a big lake that's perfect for swimming. Three small beaches are also available for sunbathing and relaxing, but you can forget about tanning your nether regions as De Oeverlanden is very popular with families and local teenagers. If you get hungry, decent food is available at Pavilion Aquarius and cheaper meals can be had at a snack stand. Take tram No.2 to the Slotervaart hospital and walk south for roughly 10 minutes.
