The Piz Scalottas zone lies on the western side of the Lenzerheide valley and is accessible via a two-lift system. Notably, big hit bikes with over 160mm of fork travel, full face helmets, and full body armor (compression suits) are not allowed on this side of the valley. You need to be riding an enduro or trail bike in order to ride over here.
The trails fit with that restriction, though. All of the singletrack on this side is old school hiking trails--don't expect to find a fast DH track!
