Edam is famous for its cheese. And as tiny and round these cheese are likewise is the little port town that produces them. It received its city rights in 1357. An old sea lock connects it to the Marker Lake. During high season you can visit the cheese markets and discover the surrounding by a whisper boat.
A village like this is definitely worth a visit, although a visit of 1.5 to 3 hours is mostly enough. For a fully day program do the Waterland auto route, or visit several villages in this region.
