About
Serena is a water park in Lahnus, northern Espoo, with an indoor hall and an outdoor park that opens June to August. Slides include the Tornado, Black Hole, Hurricane, an 80-meter slide and a free fall, plus tube rivers and a wave pool.
Younger kids get their own kids' land with small slides, indoors and out, and adults have jacuzzies and saunas.
