A trail that leads to Mount Wilson Observatory which was founded in 1904, the trail is the site to the second oldest race in California. Immediate destinations include First Water and Orchard Camp (the old camp used by Mr. Wilson himself).

As the trail moves into the Sierra Madre Historical Wilderness Area, a 1.5 miles gradual climb, largely front country, leads to First Water. Access to streamside rest at First Water. The next 2 miles to Orchard Camp have more shade and heavy timber. For advanced hikers, it is another 4 miles to Mt. Wilson through heavy timber and difficult switchbacks.
