Trail Overview

Imperial Gulch is an epic top-tier single track for incredible views and a smooth fast and flowy trail through meadows full of wildflowers. There are only a couple of sections with some embedded small rocks and a couple roots, but it's mostly smooth dirt the whole way. It's a narrow trail with wide sweeping switchbacks, gradual climbs, side-hilling on an exposed mountainside full of flowers, and a windy fun trail through flat meadows. There's hardly any shade as it mostly goes through grassy meadows full of wildflowers and only goes through a couple of tree sections. This is a really popular one for mountain bikers and hikers since it's close to the Greenhorn trailhead, so you have to watch for oncoming traffic.


Easier single track with fast and flowy sections, wide switch backs, and little rock.

Access Description

The Greenhorn Trails are an extensive trail system south of Ketchum Idaho that gets a high amount of use from various recreational users including mountain bikers and horses and hiking in addition to dirt biking. There's a decent-sized parking lot at the staging area for Greenhorn Trails, that can accommodate trailers, but doesn't allow camping, and gets full even on weekdays. The trails can also be accessed off of Warm Springs Road to the north and Deer Creek Road to the south, which both have places to camp. It's an extensive system with trails of varying difficulty from easy to advanced. This area can get really hot in the summer and doesn't have much shade. This area is very well signed and maintained, but most of the area doesn't have cell service, so download your maps ahead of time.
