Scandinavia's largest waterpark, Sommarland in Bø, is by far one of Telemark's most visited attractions. The park has more than 20 different pools and slides including "Magasuget" - a freefall water slide, "The Master Blaster" - Europe's only water roller coaster, and "The FlowRider" - Europe's largest artificial surfing wave.
In addition to all the activities the park offers you "weather guarantee": If it rains before 3 pm when you're visiting the park, you get free entrance the following day.
If you're not keen on getting yourself wet you don't have to worry about being bored. You can try out some of the "dry" attactions such as miniature golf, mountain climbing, Tarzan-track, park clown show stage and tivoli with fun fair and show stage. The park is situated in a beautiful forested area, just a few km outside of Bø.
