This route can be done as an out and back starting from either end. Both trailheads are at within 100 feet of each other in elevation. This route is particularly special because it can be accessed from either side of the Sierras. The mammoth trailhead, funnily  enough, being accessed from the west side off Beasore road out of Bass Lake. And the other starting point being the shuttle parking lot of Devils Post Pile national monument outside of Mammoth. So within15 relatively easy mile you can cross from a car on one side of the Sierras to a car on the other side. Starting from the East side you get on the trail heading towards devils post pile and at the Soda Springs bridge cross the river and get on the pack trail. Very shortly you will cross over the JMT and stay on the pack trail. You stay on that trail all the way to corral meadow going just below the granite stairway. At corral meadow many maps no longer show the trail but continue heading south west. The trail is still very evident. You continue through snake meadow to the North Fork of the San Joaquin River at Sheep’s crossing. The climb all the way up to the Mammoth trailhead. Then return the same way. Everything reversed if starting from the west side


Heading out to do this tomorrow morning! Hoping to go around 7 hours
