Round trips by small and shallow ditches and Vaartjes National Park De Weerribben with the purpose-built barge canal boat Sylvia. Sylvia started off from the covered boathouse (always dry and egress) to the De Weerribben Nature Activity of State Forest in Ossenzijl. From that point, people quickly into the water only accessible part of the nature reserve.
The Sylvia to places similar or larger tour boats may not or can come and sail across the reedbeds, meadows and swamps. If the weather conditions, however, leave to be desired, the boat is windproof and waterproof and, if necessary, heated.
