David Yoder, 43, Ryan Shankles, 41, and Miguel De La Torre, all of Oceanside, Calif., were located by a San Bernardino County sheriff's helicopter Tuesday morning near the Mineshaft Campground, a sheriff's news release said.
The three appeared to be in good condition, authorities said.
The men had set out on an all-day hike Saturday with a fourth friend, who decided to turn back after several hours. When the trip didn't return Saturday night, the fourth member of their party notified police, KTLA-TV, Los Angeles, said.
About 40 search-and-rescue personnel, involving a search dog, riders on horseback, Citizen Patrol units and a sheriff's helicopter were involved in the search, the sheriff's department said.
