There are easier routes from Wädenswil at the lake of Zurich to Zug but the one over Gottschalkenberg is the most beautiful. First upward a decent hill to Samstagern. The following elevation to Hütten is steeper but you get rewarded by a fast downhill track. Kilometer 11 is the steepest part leading to the top of the mountain chain through a forrest. There is a nice viewing point at Gottschalkenberg with an amazing view over the region of Zurich. On the way down at the other side you will enjoy a beautiful view over the regions of Zurich and Zug. The highest parts of the route are often above the clouds. Easy and relaxing downhill until the city of Zug via Menzingen.
