The Hike

This trail traverses some rugged volcanic terrain with good views. From the trailhead, follow the trail past the information sign and through a gate. Turn left (northwest) at the first signed junction at 0.2 mile; this is the start of the Fatmans Loop. You will return on the trail that forks to the right. The trail climbs northwest toward the imposing east face of Elden Mountain. It passes through another gate where an unsigned trail joins from the right. At 0.4 mile, you’ll pass the Pipeline Trail, which goes left (southwest). Continue on the Fatmans Loop as it turns north and climbs the lower slopes of the mountain through Gambel oak and ponderosa pine forest.

At the high point of the loop, the Elden Mountain Trail goes left (west) at 0.8 mile. Stay right on the Fatmans Loop as it continues north, then abruptly turns southeast and starts to descend, winding through huge volcanic boulders.

As it comes out onto the lower, gentler slopes, the trail meets the Christmas Tree Trail, which joins on the left (northeast) at 1.6 miles. Continue to the right (south) to the Fatmans Loop junction at 2 miles, then turn left (southeast) to return to the trailhead.
