#1 Runaway beavers
If you’re lucky, you may spot a cute beaver on your Aare rafting tour. Beavers are now at home here due to a storm that passed through Switzerland about 20 years ago. Torrential downpours and large amounts of melting snow flooded the Aare with a massive 620m3/s of water. The flood reached the nearby Dählhölzli zoo. Most of the animals were able to be rescued from the flood, but a kangaroo, a guinea pig, three flamingo chicks and numerous young beavers were swept away by the floodwaters. The beavers enjoyed their newfound freedom and started reproducing. Their great-great-great-great-great grandchildren can be observed at Belp and other locations along the Aare. By the way, beavers are a protected species in Switzerland, just like wolves.
