Description

Newly built in 2011, this beautifully made trail connects Fourmile Canyon Road to the Betasso Trail system. This particular stretch of trail is not a destination by itself, but it's a great addition to the Betasso system and gives you more options when planning a ride in the area.

There is one short section of stone stairs that almost everyone will have to walk.
