How should you choose an area?
Amstel at Amsterdam includes two distinct areas, Amstel and Berlagebrug. Compare them before booking canoeing, kayak, paddleboarding, because access and conditions may differ.
Amstel / Berlagebrug is a geographical reference for planning a visit, not a guaranteed launch point. Permission for each activity and the exact launch remains to be confirmed with the relevant authority. A beach, car park or tourism offer does not establish that permission.
