Course Intertidal hiking is crossing the Waddensea by foot during low tide, when parts of the sea bed are dry. It is mountainering in 2 dimensions. Finding your way trough sandbanks, muddy flats and gulley’s . And this whithout losing contact with the bottom. No swimming! In the 1950s a few brave enthousiasts, generally considered as odd daredevils, explored the routes trough the sea for their own pleasure. In the sixties and seventies wadlopen became a hype. In this stream some enthousiast students founded the club Arenicola. In the beginning they were taken under charge of the guides of the Wadloopcentrum Pieterburen but since 1976 Arenicola is a independant organisation with own guides who can guide safely and have a outstanding expertise in this matter. Every year we offer our members en guests a programme of about 20 tours. We try to walk all the destinations and islands of Friesland , Groningen and the Eastfrisian islands in Germany. For instance Ameland and Engelsmanplaat in Friesland and Baltrum and Wangerooge in Germany. Mostly we walk in a small group with 10 to 15 people. We ask from our participants a good health en the capacity to make a robust walk of several hours. Since the interest in wadlopen was partly due to a general increasing interest in ecology and a awareness of environment we appreciate a interested and positive attitude for these aspects of the Waddensea area. For lovers of nature and outdoorsports wadlopen is a delight. Every trip reveals special sights and encounters. You will experience the pleasant companionship of the group, the fresh air and exercize. It is a welcome break from studies. The course starts with an information evening in the sports center. This information evening will take place in 2019 on Tuesday, April 23 from 19: 30-21: 30.
