Alden Gulch (#144): If you couldn’t tell by the “trailhead,” Alden Gulch does not see a lot of traffic. On a 1915 map of the Sawtooth National Forest, the trail is shown linking over Warm Springs Ridge down Thompson Creek and is highlighted as an “Area of Scenic Interest.” The thickly wooded, north-facing drainage offers a cool hike in the heat of mid-summer. It provides access to the Warm Springs Ridge Trail (142) and makes a perfect mountain bike loop descent from the East Fork of the Baker Creek Road.
Directions: Drive north on Highway 75 to Baker Creek Road (15.4 mi). Turn left and follow the main dirt road to campsite #30, a non-descript pull-out on the right that can accommodate long trailers (3.2 mi). The trail starts in the woods on the opposite side of the road.
