This is the country's largest water park, drawing families from all over Norway during the summer. More than 100 different activities await you here, including a kids' water park (ideal for small children) and Bøverstranda ("the Beach"), along with water slides and Sommarlandelva, a 250m-long (820-ft.) artificial river. Near the entrance is the scenic lake, Steinjønn, where you can borrow a canoe for a ride. The Flow Rider is for those who love skateboarding, snowboarding, and surfing. Of course, the waves here are artificial, but they are said to be the best of their kind in the world. You can also experience Europe's first roller-coaster flume.

The latest draw is the Space Ball, a centrifugal slide that creates the illusion of being in a whirlpool. The attraction begins as visitors enter a dark tunnel before being thrown into the Space Ball, which spirals down toward the center and drops visitors into a deep pool. There's also a big amusement area, Las Bøgas, with a Ferris wheel, an amusement arcade, merry-go-rounds, and lots of games. Family-friendly entertainment, from clown shows to band performances, is also presented daily. The park lies 50km (31 miles) from Skien and 25km (16 miles) from Notodden.
