Rent a kayak in the centre of Karlstad and paddle the Klarälven river, with or without a guide. During June-August, group tours are organised with a leader for 495 SEK/person. We are out about 3 hours including break. See the website for times and dates.
Backwaters kayaks can also be booked with self-service around the clock. Go to https://www.kayakomat.com and select KAYAKOMAT KARLSTAD TEATERPARKEN. You get a code to your mobile phone and can pick up the kayak in the rack at Wermland Opera. Life jackets and paddles are in the cockpit.
