In Avaldsnes you will find a fun family activity. An old barn has been rebuild into a two-story minigolf. You work your way into the barn at one side, and down one floor inside the barn. Animal figures has been put up several places, some even making sounds when you hit different targets.
There are also other tracks, equally well designed and a small cafeteria and restrooms. There is a regular golf course adjacent to the minigolf. So if you are a real golfer, you may have a swing at it here while the rest of the family do the mini version.
