It is also believed that Tanner Canyon was once used as an old horse thief trail where buried gold known as Long Tom's treasure is located.

The trailhead for the Tanner Trail is located near the parking area at Lipan Point, which can be accessed by the Desert View Drive.

At this point the trail makes its second major descent, dropping off the plateau into the lower Tanner Canyon.

This trail is only recommended for seasoned hikers, as it is very steep, rocky, has very little shade, and the only water source is the Colorado River.

The National Park Service recommends boiling, iodine tablets, or filters in order to purify the water.

There are multiple "campsites" along the trail, but the main camp area is located at Tanner Rapids, a spot that is popular to rafters.

The camp area is located at the end of the Trail, situated between the dunes to west and the river to the east.

The sand dunes to west are off-limits to camping and foot-travel, as the Park is attempting to revegetate and stabilize the area .

These include all types of scorpions, snakes, spiders, centipedes, mice, deer, big horn sheep, and mountain lions.

The most dangerous and venomous of these animals are the black widow spider, the Arizona bark scorpion, and the rattlesnake.
