If you do not like to be packed on a canal tour with a bunch of other people, you can also rent a water bike.

For the lazy between us, a organized canal tour is the best. For the ones who do not fear a little working, renting a water bike is a fun way to cruise the canals of Amsterdam. You are not packed on a canal boat, you can decide your own route and you can decide your own pace. Especially with good weather this renting a water bike is fun to do.
But watch out, the canal tour captains are not really careful. You will not be the first one to be hit by a canal boat.
