Home to dolphins, sea lions, walruses and seals which perform in various different shows, the popular Dolfinarium is the largest marine wildlife park in Europe. The park also has a pool where rays are kept (these can be stroked by visitors), as well as a lagoon where underwater life can be admired and, back on land, a 3D film about pirates and the adventures of the SOS Barracuda. Beached dolphins are looked after at Fort Heerewich.
