Cast your line directly from your camping pitch. You can... at Wedderbergen. All you need is your National Angling Card for a great vacation. Or try fishing for carp in the nearby Weddermeer. This where the big boys live; 30 kilo plus, looking to bite. You need to purchase a carp fishing permit at the Restaurant on Weddermeer (avoid disappointment, book in advance!).
During the Bouwvak [Construction Industry] vacation period the campsite organizes fishing contests twice a week for all ages.
