A Toeristisch Overstappunt - touristic transfer point (TOP) is a place where you can park your car and take a glorious cycling or walking tour through the rural surroundings. From every TOP, you can follow sign-posted or documented routes that take you to the most beautiful locations.
From TOP Hollandse Biesbosch, you can explore Europe's largest freshwater tidal area, with tidal willow groves, meandering brooks, rough paths and open meadows teaming with water birds.
