Hiidenlinna Park Resort & Sisumetsä Adventure Park

Hiidenlinna Park Resort sits in Somerniemi about 20 km from central Somero. The site is centred on a stone castle and the Sisumetsä adventure park. The park has ten rope courses of varying difficulty, with the three easiest open to children from age 2 with an adult, and a black-graded tenth course challenging experienced climbers with a Tarzan jump. A single area ticket covers the zoo with alpacas, reindeer, sheep and ponies, plus a Troll Forest, a bouncy castle world, trampolines, a pumptrack, skate ramps and an artificial-turf football pitch. Standout features include a 15-metre Giant viewpoint, a Lapland zone with Santa's workshop and the K.I.T.T. car from Knight Rider. Buggy karting costs extra, but children aged 2–5 have their own free track. Two restaurants and a grill café serve on site.
