This loop trail system includes a 3/4-mile trail designed for maximum accessibility (grade and slope) from the trailhead down to the Big Lost River. For those wanting a more arduous hike and a spectacular view of Mt. Caleb, a side trail, also 3/4-mile hike, provides the second half of the loop.
Approximately 1 mile northwest of Mackay, Idaho along the Big Lost River. Northwest of the River Park Golf Course in Mackay. Head due west off of Beverland Road.
