On this site you can see when the popular kayaks are already booked. If you want to borrow the kayaks, please contact the people responsible of kayaks by filling the form for lendable items (kajakit = kayaks). The person contacting you will add information of your booking to the calendar when it is confirmed, so other people can see when the kayaks are already booked.
NOTE: it’s up to people responsible of the kayaks whether the bookings are marked on calendar. Therefore you’ll get up-to-date information only when you’re booking the kayaks. So please book them early if possible to avoid surprises. Please also note that people responsible for the kayaks are volunteers, so they may not be able to fulfill your wishes everytime.
