This one is going to stay in your memory:
You can park at the Söllereck Nord parking ground.

First, ascend the Fellhorn. Especially at night, you can enjoy a spectacular view over Oberstdorf. Then you follow the ridge and stay at the east side. If you are there at the right time you can see an amazing sunrise. The first really good point to fill up your flasks/eat something ect. is at the Mindelheimer hut.

Spanning two of Vermont’s premier trail systems, this route combines the Westmore Challenge and Kingdom Heritage Trail into one incredible adventure! Reaching 11 peaks in total and covering nearly 50 miles, it is the longest route of its kind within Vermont’s Northeast Kingdom. The Kingdom Heritage Trail is already an FKT route, but the addition of the Westmore Challenge route makes it twice as long and adds several more peaks and incredible landscape.
