Some of the smallest monkeys you've ever seen are on show in this zoo and aquarium inside Skansen. Bright orange tamarins and pygmy marmosets hang from trees behind glass, and you can walk up the steps of a giant tree house where more than three dozen striped lemurs hop around while chewing on fresh vegetables. The less friendly-looking baboons crawl around a steep hill in another exhibit, complete with a crashed jungle jeep hanging from a branch. You can even pet a boa constrictor and a tarantula. There's lots to see - snakes, a nocturnal room full of bats, and two crocodiles (given by Fidel Castro to a Russian cosmonaut before ending up here). If you don't want to pay the separate entrance fee, you can watch the baboons and lemurs from outside.
Young children might find the old buildings a bit dull, but the animals are always a hit. The regular zoo (feeding time 2pm daily) specialises in Nordic animals, among them brown bears and wolves. At the children's zoo, Lill-Skansen, kids can pet Swedish farm animals. Adventurous kids can also pet snakes and spiders in the small aquarium (Akvariet; separate entrance fee). The charming Galejan amusement park has rides dating back to the 19th century. Every Wednesday from May to September is children's day, and kids get to ride two for the price of one. Other diversions include guided pony rides, horse and carriage rides and a mini-train ride. Some sights are only open during the summer.
