Dolfinarium Harderwijk

General Information
Opened: 1965
Location: Harderwijk, Netherlands
Type: Marine mammal park / zoological garden

Dolfinarium Harderwijk is a marine mammal park in Harderwijk, situated on the shores of the former Zuiderzee. The first plans for the park date to 1955, when brothers Frits and Coen den Herder began developing facilities for marine mammals. The Dolfinarium officially opened to the public in 1965 and became one of Europe's early specialist marine mammal parks.

The collection focuses primarily on marine mammals, particularly dolphins, sea lions and walruses, alongside other aquatic animals. Over its history, the park has also kept a range of other marine species and developed facilities combining animal habitats with educational presentations. Today, the Dolfinarium combines its zoological collection with recreation, education and conservation-oriented activities.
