Approximately 16-18 mile (roundtrip), 1200 ft. gain hike from the Heaton Flat parking lot to the Bridge to Nowhere, continuing on to the East Fork Narrows and then up Iron Fork past the Iron Fork Camp. Iron Fork is fun because it is beautiful and not many people go up there. Slowpoke paced hike along the wild and beautiful East Fork of the San Gabriel River through the Sheep Mountain Wilderness area. Some boulder hopping, rock scrambling, SWIMMING, and lots of stream crossings. The bridge is 5 miles from the parking lot, and Iron Fork is 2 miles from the bridge. The campground is about a quarter mile from the East Fork, then we will go another mile or two up Iron Fork.

It takes about 30 minutes to drive to the trailhead from the rideshare point we are meeting at in Azusa (directions below).

SATURDAY we will hike past the Bridge to Nowhere to the Iron Fork Campground (or someplace near there) and set up camp. That will take about 5-6 hours. We will then EXPLORE up Iron Fork for about 3-4 hours. The canyon gets narrow and REQUIRES SWIMMING in some spots in order to continue up the canyon. At some point we can abandon our packs in order to continue up the canyon more easily, then pick them up on the way back. YOU MAY WANT TO BRING DRY PACKS OR DRY BAGS OR AT LEAST TRASH COMPACTOR BAGS TO PUT YOUR PACK/STUFF IN.

SUNDAY we will tear down our camp and hike back. We may go the "Troll Route", going back under the bridge off trail (more scenic but also more time consuming and rocky and wet).

Note: You WILL get WET! This is a challenging hike mainly because it is long and some off-trail exploring. You will need energy!

If you think you might want to go faster than the leader and stray from the group, please don't sign up for this hike. For social and safety reasons I would like the group to stay together. Slowpokes only!

BRING: At least 2 quarts water, meals, snacks, change of clothes, warm clothes (especially for night time)(ie. coat, hat, gloves), HIKING SHOES OR BOOTS THAT CAN GET WET, sleeping bag, toiletries, flashlight or headlamp. OPTIONAL BUT HIGHLY RECOMMENDED: bathing suit, dry bags, pad for underneath sleeping bag, bear canister or cord to hang food, clean dry clothes to leave in car for drive home.


You will need an ADVENTURE PASS if you plan on driving to the trailhead from the rideshare point. They can be purchased from Sport Chalet or REI or any ranger station. There is a booth to buy them at in Azusa, but you can't always depend on it being open.
