Tanner Trail via Lipan Point
This is a difficult one way trail in Grand Canyon National Park. It is perhaps the most secluded trail to access the Colorado River from the South Rim within the national park.
The first mile going down from the top is especially difficult as you descend with big steps over large rocks. Trekking poles are a must if you have any weight on your back.
Enjoy a variety of landscapes as you descend.
Tanner Beach (the end of the trail) is frequently used by river raft groups, so you may have company at the campgrounds. There is a vault toilet and there are many established sites to set up a tent. Lots of little sites would allow seclusion even with lots of other people around. The sound of the rapids would drown out any noise.
Park at Lipan Point and hike back about a hundred yards toward the highway. The trail head will be on the left (east) side of the road.
This is a strenuous hike, but it's not especially dangerous. There are many risks of slipping where the surface is loose while traversing the side of a steep hill, but there is little risk of a substantial fall. This trail is challenging for even athletic adults. This trip should only be attempted with children if they have extensive hiking experience.
