Mount Islip, Mountain peak in Angeles National Forest, California, United States
Mount Islip rises to 8,250 feet within the San Gabriel Mountains and offers views of the Mojave Desert and the Los Angeles Basin. The summit is accessible via multiple hiking routes, including the path from the Islip Saddle parking area.
A steel fire lookout tower was built on the summit in 1927 and housed one of the first two-way radios used by the Forest Service. This installation became instrumental in early fire detection and communication across the region.
The peak serves as a regular stop for long-distance hikers following the Pacific Crest Trail across the western mountains. Many travelers consider it a meaningful waypoint in their multi-week journeys through diverse landscapes.
The hike offers varying difficulty levels and can take anywhere from a few hours to a full day depending on the route chosen. Camping facilities are available nearby, including Little Jimmy Campground, for visitors who wish to stay overnight during extended trips.
Remnants of an old stone cabin sit on the summit, a hidden relic that visitors can discover while reaching the top. This structure tells the story of people who once inhabited this remote location long ago.
