The Seeteufel zoo and adventure park is located in the south-east of Biel. Covering an area of seven hectares, it is home to 40 animal species and, above all, a wide range of play opportunities for children. In addition to an aqua park, a train around the lake, swing games and climbing areas, there is also an adventure trail. In the afternoon, there are show feedings of calicoes, otters, nutrias and caimans. Children can ride ponies or get up close to the animals on the petting meadow. A mini train takes young and old around a pond in the old Aare nature reserve.
