It's a tour around the island of Texel in North Holland, Netherlands. The idea is to circumnavigate the island as close to the sea as possible (with the exception of the very south end). Along the east shores follow the trail and/or biking paths with view to the sea (on or along the schans/bank/rampart). On the westside it is possible to run on the beach or use the paths that go there. Be careful when passing the river outlet at De Slufter. At the south end shift to Jan Witter paadje/trail and go between the lakes.
