Heart Trail No. 103


The Heart trail begins in the Sandy Seep area just north of Flagstaff at approximately 7200 feet, and climbs the east slope of Mt. Elden to connect with the Sunset Trail in Sunset Park. As the trail climbs, it winds through the remnants of a large mixed conifer forest which was destroyed by the Radio fire in 1977. The area is well into regeneration, with gamble oak and various grasses and shrubs growing strong.

The Heart Trail can be accessed from a number of trails: Little Elden Trail, Sandy Seep Trail, and Sunset Trail. (The Google Map shown below shows Sandy Seep Trailhead.)
