The locks of IJmuiden give access to the sea.
Amsterdam is close, so are the beaches of IJmuiden or Wijk aan Zee.
Go visit Haarlem (also known as small Amsterdam) for a great shopping experience or walk through the narrow streets of Spaarndam. Beautifully located at the waterfront.
Lots of nature to be explored in the dunes and parks nearby.
For a quick intro we made this gallery. Enjoy !
