Overview

The Heaton Flat Trail and the south ridge is the most common way to reach Iron Mountain, a round trip by this route is about 14 miles and 7,200 feet of elevation gain. Check the weather before attempting this route. Do not attempt during this summer as this route gets little shade!

Getting Started

From Interstate 210, take the Azusa Avenue (SR 39) exit and go north winding up San Gabriel Canyon about 12 miles to where the East Fork Bridge intersects SR 39. Turn right, go across the bridge, and continue straight. In about 5 miles, you will come to a point where the road starts to curve very sharply right and uphill. Right at this curve, you will see a road straight ahead of you. Continue straight onto this road and in less than a mile you will come to the large paved parking lot at the end of the road overlooking the East Fork of the San Gabriel River. Park here. The trailhead is at 2,030 feet elevation and you need to get to 8,007 feet.

You will need an Adventure Pass to park at the trailhead.

    Recommended that you do this hike on a cool weather day. No water sources on this trail you have to carry all your water with you. It was 85° and i carried 6L and it was barely enough. Drank 1L the 1st 3 miles stashed 2L at the saddle for the way back kept 3L with me. The uphill is steep and the downhill feels steeper. Pants and boots reccomend you might be able to get away with trail runners. Definitely a Very Strenuous Advanced hike.
