We open 13 May (if the water temperature is above 12 degrees) until 26 September 2021. It is possible to book kayaks between 9.30-18.30 every day. If you want to be out later in the evening, put it in the message in the booking and pay the difference on the spot.
When you book, you first choose which kayak / canoe you want late dates. Then you choose what time you want to start and what time you are back. Then you get the price of your booking. You then go ahead and pay for your booking.
