This trail isn't called the Panorama Way for nothing; it is just awesome. The singletrack twists in and out along the side of the mountain with views of Davos and the Davosersee Lake as well as the glacier covered peaks to the east.
Unlike some of the other trails in the area, the climbs and descents on this trail are pretty gentle and overall the trail generally hugs the side of the mountain around 2300 m (7500 ft). So it's a pretty easy ride for those who don't want to or can't do a lot of climbing and/or descending. You could really carry some speed on this trail, but it is also very popular with hikers so keep it under control.
This trail starts at the Strelapass, which you can reach either by riding up from Davos or taking the Parsennbahn funicular railway followed by the Parsenn to Strelapass
trail. It ends at the Gotschnargrat summit where the Gotschnaboden cable car connects to the village of Klosters also offering easy access.
From Gotschnargrat summit, you can take the very difficult Gotschnargrat Descent
back towards Davos, but there is not an easy route down to Davos or Klosters from Gotschnargrat. If you're riding it in reverse or doing it as an out-and-back ending at Strelapass, there are lots of easier routes down to Davos.
The most difficult thing regarding the Panoramaweg is trying to decide what to enjoy most: the ride or the views. Just concentrate on the ride enough not to cause any hiker-biker conflicts.
