Yesterday, while rejoining the trail down to Little Round Valley at 10,300' after a cross-country hike to Folly Peak, we encountered two men walking down the trail. We asked them where they were heading and they said the Tram Station. Neither had a map and didn't realize they were headed in the wrong direction. (They had gotten separated from a third member of their party who was their "navigator.") We took out our map and showed them where they were at and the correct turn to take once they hiked back up to the trail junction.
The State Park website has a good map of the San Jacinto Wilderness on its website, with mileage distances between points. It can be found at:
