Otay Mountain

Otay Mountain is a summit in the San Ysidro Mountains standing at 3,566 feet (1,087 meters) with sheer canyon walls and sharp ridges across the landscape. The terrain features diverse topography with significant elevation changes that make hiking physically demanding.

The Otay Mountain Wilderness gained protected status in 1999 when President Bill Clinton signed legislation to preserve this wild region. This protection ensured the landscape would remain undeveloped and accessible for future generations.

The name comes from the Kumeyaay word 'otai', linking this place to the indigenous peoples who lived in the San Diego region long ago. Walking through the landscape, you encounter this heritage woven into the terrain itself.

Several trails climb to the summit through the wilderness area, offering different route options for hikers. Prepare well for this remote location by bringing plenty of water and sturdy footwear, as services are sparse.

The mountain slopes hold the largest concentration of Tecate cypress trees found anywhere in the world. This forest is home to plant species that survive in few other places globally.
