Dirk · FamilyNLNetherlands

The price was reasonable at €10.00 per person. Since the island was incredibly busy, we opted for a short visit. A text message was enough to get picked up again 10 minutes later. Other boats have a more extensive program with sightseeing stops and swimming stops. If you want more freedom, the boat taxi is a great option.
