Today, easter Monday I did one of my favorite tours for race bike. It is quite a fast tour but has more than 1000 meters difference in heigt.
You go from Einsiedeln down to lake Zürichsee, from there to Siebnen, a small village a little off the lake and at the foot of the mountains. From there it goes up to the small lake Wäggitalersee. A few kilometers before you reach the lake, there is Vorderthal from where it goes more up the hill, to Sattelegg.
Up on Sattelegg, you just can go down to Sihlsee lake and from there it is just a few kilometers back to Einsiedeln. Very nice round. I had 2 hours and 2 minutes. Very nice tour!
