Beginning of August we went for a round walk hike in the little town Baar in the canton Zug in Switzerland. It is an easy walk along the Lorze river with lots of shade from the surrounding trees. There are plenty of spots to go for a swim in the river with public BBQ spots. If you have enough time you can relax there and cool off in the fresh mountain water.
Along the round walk you can explore the Höllgrotten caves which is a natural 3000-year-old limestone cave system with stalactites and stalagmites. The Höllgrotten were discovered in the late 19th century and was later turned into a public place to visit after the calcareous spring water was diverted. Today the stone formations are illuminated by colorful LED lights which gives the whole walke through the cave system a fairytale experience. The temperature in the cave is nice and cool, especially when the outside temperature is around 30° Celsius. The tunnels are well connected and signs throughout provide interesting information in German and English.
