Southwest of Sun Valley, the Red Warrior Creek route is an eight mile route with 1,700 feet of elevation change. The route runs through beautiful pine and aspen forest. The wildflowers are amazing during mid-June.
While this trail can be ridden as an out-and-back from Warm Springs Road, the upper end of the trail ends at the intersection with the Greenhorn Gulch Trail. Therefore, many local riders drop a car and ride up Greenhorn (6 miles / 2,100 feet) or Mahoney (6.2 miles / 2,100') and then descent the eight miles down Red Warrior to Warm Springs Road. The bonus is that the Frenchmans Hot Springs is located 0.5 miles east of the Red Warrior trailhead on Warm Springs Road.
To reach the Greenhorn Gulch trailhead from Ketchum, head south on SR75 for 5.5 miles. Turn right heading west on Greenhorn Gulch Road for 3.5 miles to the trailhead parking area.
To reach the Red Warrior Trailhead from Ketchum, head west on Warm Springs Road for 12 miles.
