Längenegg Pass

Nice tour
With the e-bike I would go up via Klöntalersee. You can ride anything there, except maybe one or two short steep sections where you can lose grip depending on the road conditions. From the Obersee you have to carry the bike up the last 200 meters to the pass. Pushing is not so easy. The path is too rough and too narrow.
To all e-bike riders (I now ride an e-bike myself and it's fun:-)) the route is listed as 304 by Switzerland Mobil and is described as technically difficult. I have seen some e-bike riders who pushed sections where I also ride with a normal bike. All I'm saying is that you should have a bit of MTB technique (up and down). I don't mean any harm, but I just felt a bit sorry for the people and I wouldn't have had any fun like that.

Finally up. View into both valleys, but not to Klöntalersee. This one does not see the whole descent over, first down at the Klöntalerstrasse. Coarse gravel with toxic ramps, if you come from the alp "Ober Längenegg". Coming from the north, from the "Ober Lachenalp", then should be announced push (with us also downhill). But we also saw a Frenchwoman (?), Who carried her e-bike up there.

Absolute experience, both scenic and botanical! From the Obersee side the bike has to be pushed for about 20 minutes, from the Klöntaler side you can drive up on a steep gravel road.
