Grand Canyon National Park - Grandview Tonto Loop Extreme Dayhike

The Grandview Trail was originally constructed by a prospector by the name of Peter Berry. Berry operated a copper mine called the "Last Chance Mine" at the end of the trail, out on Horseshoe Mesa. Berry later used some of the profits from the mine to build the Grandview Hotel out on Grandview Point. He operated this for some years and being the only lodging available in the area it proved to be a most successful venture. That is until the Santa Fe Railroad extended its reach up into the Canyon which sparked construction of what is now Grand Canyon Village. That pretty much put an end to Berry's operation.
The trailhead for the Grandview Trail is located out at Grandview Point on the Desert View Drive. Elevations:
Rim - 7400'
Horseshoe Mesa - 4800', 2600' below rim
Miners' Spring - 4400', 3000' below rim
Cottonwood Creek - 3600', 3800' below rim
Round Trip Trail Length: The section of the Tonto Trail is approximately 6 miles. The entire loop is (according to my GPS) is 16.5 miles down the Grandview Trail, across Horseshoe Mesa, down to the Tonto Trail, across the Tonto Trail, up to Horseshoe Mesa via the trail that goes by Page (Miner’s) Spring, and back up the Grandview Trail.
