Seven Best Mountain Hikes

Explore San Diego's Surprising Mountain Landscapes

These 7 best mountain hikes in San Diego County offer beautiful landscapes, spectacular views, and are just around an hour's drive from the beach.

By: Scott Turner, Co-author of the 5th Edition of Afoot and Afield in San Diego County

Beyond the quaint mountain towns and historic gold mining districts, San Diego County's mountains contain some of its most surprising landscapes. These mountains, known as the Peninsular Ranges due to their association with the Baja Peninsula, rise gently from the inland valleys, attaining heights sufficient to support coniferous forests. The higher peaks offer commanding views across much of Southern California. On the mountains' eastern boundaries, the terrain falls away spectacularly into the arid expanses of Anza-Borrego Desert State Park. Few visitors expect to encounter lush meadows graced by a parade of wildlife or trickling streams under the cool shade of pines and oaks. Yet, you'll find all of that and more an hour's drive from San Diego.

A Note About Mountain Climate

Unlike the rest of San Diego County, the mountains here experience traditional seasons. Snow is known to fall in depths of up to two feet, necessitating chains and also inspiring caravans of curious San Diegans to head up from the lowlands. Winter precipitation is often three times heavier than at the coast, so you will definitely want to check the weather reports before visiting. Fall brings with it golden foliage, while the vibrant wildflowers of spring arrive later (May and June) than along the coast and interior. Summer brings occasional intense thunderstorms, and during those times, lightning can be a concern.
