Sheep Mountain Wilderness

The United States Congress designated the Sheep Mountain Wilderness (map) in 1984 and it now has a total of 43,182 acres. All of this wilderness is located in California and is managed by the Forest Service. The Sheep Mountain Wilderness is bordered by the San Gabriel Wilderness to the east.


In 1984, the 44,000 acre Sheep Mountain Wilderness was set aside as one of the Nation's truly unique wild areas. With elevations ranging from 2,400 ft. to over 10,000 ft., this area offers something for everyone. Whether you're a novice hiker, an experienced backpacker, a fisherman or just interested in the "great outdoors", this rugged terrain provides a variety of opportunities for all. We are also proud to mention that the Sheep Mountain Wilderness is also now within the newly designated San Gabriel Mountains National Monument, which was designated on October 14, 2015. A Wilderness Permit is required for entry into the Sheep Mountain Wilderness from the East Fork Trailhead only. This area traditionally receives heavy water-related recreational use. The Permit system allows the Forest Service to make decisions to ensure better protection of the wilderness resources. When entering from the East Fork Trailhead please observe the following Permit rules: Keep party size small (under 25people) to minimize impacts. Obtain a Wilderness Permit at the self service box at the East Fork Parking lot, or along your hike in at Heaton Flat Campground. Permits requested by mail must be received two weeks prior to the date of entry. Any activities associated with mining which include, but are not limited to: prospecting, location, digging, and sluicing are prohibited in and around the Sheep Mountain Wilderness. See Wilderness regulations for more details. Trails that go through this wilderness include: - Vincent Gulch/Mine Gulch - East Fork Trail to The Narrows - East Fork Trail to Iron Fork/Fish Fork - Alison Mine - Fish Forks - Dawson Peak - Mt. Baldy - Heaton Flats to Iron Mountain - Big Horn Mine
