The Cutthroat Trail is a 5.5 mile trail above the East Fork of Hermosa Creek beginning at the intersection of Relay Creek and Cascade Divide Road. The trail will be built in two phases. Phase one began in 2021 when crews established the initial 3.7 mile alignment from Cascade Divide Road to Sigg Creek Campground. This section is now open. Phase two (2023) will continue from Sigg Creek to the Upper Hermosa Park Trailhead. The trail was designated in 2017 through the Hermosa Special Management Plan, which was a public planning process. Multiple Forest Service-authorized activities occur in the east fork Hermosa area, and the San Juan NF asks trail users to please leave gates closed behind them due to active grazing allotments.

This trail is open to mountain bikers, hikers, trail runners, and Class1 Pedal-Assist e-Mountain bikes (no Class2 or 3, no throttle and no motos or ATV/UTV allowed).
