Analysing terrain data
The exposure grade describes the potential consequences of falling or slipping off the path.
Low Exposure: The path is on completely flat land and potential injury is limited to falling over.
Medium Exposure: The trail contains some obstacles such as outcroppings and rock which could cause injury.
High Exposure: Some trail sections have exposed ledges or steep ascents/descents where falling could cause serious injury.
Extreme Exposure: Some trail sections are extremely exposed where falling will almost certainly result in serious injury or death.
This tour from Lenzerheide to Arosa and back via the Furcletta and Welschtobel Trails is truly epic, ridiculously challenging, and quite possibly one of the most beautiful trails in the world. From the top of the Rothorn lift, you'll drop down into a stunning alpine bowl via an ultra-rocky, very technical singletrack trail.
Once into the bottom of the bowl, the trail climbs steeply up to the first pass via a roughly 1-hour hike-a-bike.
Drink in the views from the pass, as the traverse down and up to the second pass is also quite difficult.
But once on top of the pass above the stunning Welschtobel Valley, it's all gravy! The descent down the valley is absolutely stunning.
The singletrack flows down scree-filled singletrack, crosses alpine streams, and batters the rider through rock gardens.
It's difficult to keep your eyes on the trail, though, with stunning mountain peaks surrounding you in every direction and an absolutely beautiful valley dropping away in front of you.
Don't ride too fast—enjoy every minute of it! Once down in Arosa (a great halfway lunch stop), a two-lift combination brings you back up the mountain.
The ride isn't over yet, though: a difficulty traverse through a high alpine valley is required to reach the final ultra-steep descent down through the Rothorn zone and back to Lenzerheide.
