Telegraph Peak, Mountain summit in San Gabriel Mountains, California, United States.
Telegraph Peak rises to 8,985 feet in elevation, featuring steep ridges and trails that wind through diverse mountain landscapes of the Cucamonga Wilderness.
The mountain received its current name in the 1890s, replacing its previous designation as Heliograph Hill, reflecting the evolution of communication methods.
The peak forms part of the Three Tees trail system, connecting with Timber Mountain and Thunder Mountain for a traditional hiking circuit.

The mountain offers direct views of the Lytle Creek Drainage, Cajon Pass, Mount Baldy, and Mount Harwood from its elevated position.
