Location
Alamo Mountain, the Spanish name for the poplar trees found in the area, is the tallest peak in the Cobblestone Complex yet one of the easiest hikes.
Forested Route 1 was damaged in 2006 Day Fire and down trees can present a challenge. Black Oak and Jeffrey Pine forest shade more of Route 2 from Twin Pines Campground. The spur road is less passable than it used to be but most vehicles can park at the junction with Forest Road 7N01.
