Fun and ecology – what’s not to like? This no-snow-required bobsled in leafy Langenbruck outside Basel incorporates one kilometre of hair-raising slide, a 540-degree helter-skelter – and a solar-powered lift to carry visitors back to the top. Thanks to this photovoltaic technology, you can stay put in your bob for the entire round trip. Race down at full speed if you choose, but there is also a brake to help regulate speed. If you pay attention to the information panels at the valley station, you’ll know that the solar power can be stored, meaning SolarBob is also open on cloudy days. In case of bad weather, check the website for opening times.
