Very cute. There's a protected swimming area for children, and there are flowers on the picnic tables :-))

Very nice guesthouse with lots of small restaurants and cafes. Cozy and nice view of Lake Vänern, lots of seating around the harbor. Opposite is the Ekkuden nature reserve.

Nice harbor along the edge of the lake with great food, drink, and ice cream options. I suggest ordering a generous scoop of your favorite ice cream and enjoying it in the sunshine.

The organ goes back to an instrument built in 1860 by the organ builder Per Larsson Åkerman. Pipe material from this instrument is still available, as well as the magnificent organ case. In 2011 the instrument was reorganized. It has 45 registers on three manual works and pedal. The key action is mechanical (main and swell works are equipped with Baker machines), the stop action is electric.
