A hike through the beautiful Kaltbrunnental feels like stepping back in time. Archaeological findings show that ancient humans lived here as hunter gatherers more than 12000 years ago. Along the trail you will come across several caves and it is believed that some of them were once used as shelters by early humans. Many of these caves still exist today and can be explored during the hike.
As you walk through the valley especially in spring the landscape comes alive with fresh greenery. Wild garlic covers the forest floor and fills the air with its distinct scent. The hike usually starts from Grellingen and for the best experience and views continues up to Kloster Beinwil.
