Hike to the lake "Nussbaumersee" and back, 3 to 4 hours.
The monks of Ittingen were in possession of the Nussbaumer lakes and obtained fish from them for their meals. The protected area around these lakes is today considered a landscape of national importance due to its history and valuable habitats for rare plant and animal species. A hike in the Seebach valley and around the lakes is an experience in every season. From Kartause Ittingen, the path leads over meadows and fields, past farms and the Helfenberg castle ruins. The hiking time can be halved by taking the post bus to or from the lake area (stops at Hüttwilen, Stutheien or Nussbaumen, Tobelbrunnen).
