Beemster is in North-Holland.
The anual "Beemsterfeest week", a week in which all sorts of activities will be held.
This can be the "Beemstercross", which is a combination of rally and demolition derby on a slippery muddy parcour. If you sit front row you're guaranteed to go home covered in mud.
Another activity that will be held is the fair, where locals come to every night of the week to drink some beers and talk.
The Beemster is home to several B&B's and some hotels, you can choose to sleep in the countryside or in the city. Many choose to sleep in the counrtyside because it offers a spectaculair view waking up and it's a great place to start your tour through the Beemster.
