On the quayside at the southern end of Windermere, this excellent aquarium has wildlife and waterside exhibits. One highlight is an underwater tunnel walk along a re-created lake bed, complete with diving ducks and Asian short-clawed otters. Piranhas, rays, and tropical frogs also have their fans, and there are some unexpected treats such as marmosets, a caiman, and Cinder the boa constrictor. A friendly, knowledgeable staff is eager to talk about the animals. Animal handling takes place daily at 12:45 in the rain-forest areas. Tickets may be cheaper if booked in advance online.
