The longest hike in a while (~2000 m elevation, ~30 km). Midsummer, around 32 °C in the valley, so we had to get up and out. By Adrian's suggestion, we were hiking the UNESCO biosphere Entlebuch (image film below), where you find a lot of hill moors, old forests, and all kinds of cool wildlife (frogs, lizards, birds of prey, etc.). It was even warm enough to do some wild camping. Very fun weekend, two nights under stars!
