A walk on the ramparts or a cruise by an electric whisper-boat is recommended. You can eat, shop (Het Arsenaal and little boutiques) and enjoy culture at the galleries and the various museums (including the fortress museum). Special is the painted wooden ceiling of the St. Vitus Church (14th-15th century). Every year, on Good Friday, there is a performance of the Matthäus Passion, attended by members of the Dutch government and celebrities. You can find the statue of Comenius, the Czech philosopher, in front of the church. The beautiful preserved town hall (1601) is a good example of Dutch Renaissance style.
For over a 100 years the Naardermeer is a unique nature reserve, famous for a great variety of birds. You can visit the area by taking a boat trip with a forester, a walk around the lake or a bike ride on quiet roads.
