Aquaria Vattenmuseum, Stockholm

The entrance to this water museum is under a cascade of water. Inside there is an artificial jungle with showers, piranhas and mud skippers. The children's favorites are the frogs that almost look like candy in all different colors, and the enormous sharks swimming in the glimmering water. The museum offers a unique real adventure to crawl into the shark aquarium and look up at the awesome creatures. Outside you can watch the salmon, jumping into the artificial streams. Check the website for opening times, as it varies for each season.
