If you are tired of taking the usual tour, you can take a walk to the Oude Kerk at the Red Light District, which is an old church of the Gothic-Renaissance era. You can also go to the Dam Square which is the center of Amsterdam, and is the site of a lot of important events in Dutch history.
For a little bit of peace and quiet, visit the Begijnhof which is a narrow passageway that leads to a garden for the Beguine nuns and the oldest abode in Amsterdam. Then, you can take the canal tour back to the hotel to experience the beauty in Amsterdam.
