Gilman Peak Professional Review and Guide
"Gilman Peak’s bald summit, barely poking over lesser ridges, affords a breathtakingly spacious view of Southern California on a clear day. To the southwest lies the wide mouth of Santa Ana Canyon, scored by a broad flood channel carrying runoff that originates far inland amid the San Bernardino Mountains.
Beyond, the vast urban plain of Orange County, resting on a vast sheet of alluvium, slopes gently toward the ocean. Northward, the gaunt San Gabriel Mountains, snow-capped in winter, rise boldly over foreground hills and valleys. In the southeast, the Santa Ana Mountains form a broad, dusky blister on the horizon. **Note that at the time of this writing, the North Ridge Trail is temporarily closed due to severe erosion."
