The Klosters Overlook travels mostly through a dense forest on forest road, so you won't actually have much of a view of Klosters or much else except for the occasional break in the trees.
It's nothing special compared to the other trails in the area, but it's a useful connector as part of the Durannapass
loop. It does have some steep climbs and descents, but none of these are particularly long and the route is a forest road so they also aren't particularly difficult either.
When you get to the Cavadürli train station about three miles into this segment, you'll begin a 150 m (500 ft) climb to the Davos-Laret station. Or you can take the road from Cavadürli station down into Klosters if you are headed that way. Past Cavadürli, the trail parallels the train tracks most of the way into Davos-Laret station, so you may have the train to keep you company.
