Southeast of Salt Lake City and Spanish Fork in the Unita National Forest, the Fifth Water Trail (#015) is a 9.3 mile hiking route through a sage brush canyon. The route is divided into two sections: the lower section and the upper section. The lower trail is 4.7 miles and is shared with hikers, mountain bikers and horseback riders. Although, it is very popular with hikers using the trail to access hot springs at the two mile point from the southern end. The upper trail section is 4.6 miles and is shared by hikers, mountain bikers, horseback riders and dirt bikers. Although, this section is pretty much used exclusively by mountain bikers and dirt bikers.
The southern end of the lower section is accessed by the Three Forks Trailhead. The northern end of the lower section and the southern end of the upper section (i.e. mid-point of the entire trail) is accessed by the Fifth Water Trailhead.
