If you arrive in Amsterdam and the sun is shining you should consider yourself a very very lucky person. Hence forget that you are a tourist and act as an Amsterdammer. How? Just enjoy every sunny second! A good way of doing it is relaxing in the parks:
The famous and central Vondelpark, with its film museum and nice bars on the water:
Westerpark with statues in the lakes and the former Gas-Fabriek: an industial building turned in bar and cinema.
The romantic and old Sarphatipark, in De Pijp.
Oosterpark, close to the Tropen Museum.
Rembrandt Park, more wilde, quite and relaxing.
Erasmuspark, in the West.
Amsterdam Bos: the Amsterdam forest, with its open air theater and its cheese farms.
And don’t forget to have some sex in the parks.
