Directions: From Interstate 210, take the Azusa Avenue (SR 39) exit and go north for about 12 miles to where the East Fork Bridge intersects SR 39. Turn right and go across the bridge. In about 5 miles, you will come to a point where the road starts to curve very sharply right and uphill. Before the curve, you will see a two way road straight ahead of you signed "Not a through street". Drive straight onto the right hand lane of this road and in less than a mile you will come to the large paved parking lot at the end of the road. We'll meet by the gate.

Adventure Pass is required.

"The 8,007 ft (2,441 m) peak is sometimes referenced as Iron Mountain #1 or Big Iron, was originally called Sheep Mountain by the early miners in San Gabriel Canyon because of the large bands of bighorn sheep ( that roamed the slopes. The United States Geological Survey (, which mapped the San Gabriel Mountains in the 1890s, ignored the local Sheep Mountain designation and gave it its present name. According to Will Thrall, there was once a USFS plan to change the name back to Sheep Mountain in 1940." Source: Wikipedia (

Trekking poles are highly recommended. It is steep and loose throughout the trail. This is a strenuous hike and exposed. You must bring at the minimum 3 liters of water and some type of electrolytes, food, first aid kit, headlamp, and anything else you need to complete the hike safely.

"The most coveted spot to be in the San Gabes."
