The coastal trails in San Diego get all the attention. Torrey Pines. Sunset Cliffs. The Bayside Trail in Cabrillo. But if you want elevation gain, solitude, and scenery that feels more like the Sierras than Southern California, head east. Lakeside and Alpine sit at the edge of some of the best hiking in the county, and on most weekdays, you''ll have the trails to yourself.
El Cajon Mountain (El Capitan)
El Cajon Mountain, also called El Capitan, draws 1,900 monthly Google searches and earns every one of them. The trail is roughly 11 miles round trip with about 3,600 feet of elevation gain. The first couple miles are moderate, rolling through chaparral and oak woodland. Then the trail gets steep. Really steep. The final push to the 3,675-foot summit involves scrambling over boulders, grabbing onto rock, and wondering why you didn''t just go to Torrey Pines.
But the views from the top are the payoff. You can see the Pacific Ocean to the west, the Cuyamaca Mountains to the east, and the entire San Diego urban sprawl laid out below. Bring more water than you think you''ll need. Start early. And don''t do this one in July.
The trailhead is off El Monte Road in Lakeside. Parking is limited, so weekday mornings are your best bet.
Lake Jennings Loop
If El Cajon Mountain is the hard hike, the Lake Jennings loop is the easy one. Five miles around the lake on a well-maintained trail with gentle elevation changes. Several overlook points give you views of the water, the surrounding hills, and the campground below. It''s a good morning walk for families, dog walkers, and people who want exercise without suffering.
The trailhead is at Lake Jennings Campground on Bass Road. Trail maps are available at the entrance kiosk. No dogs near the lake itself, since it''s a drinking water reservoir, but leashed dogs are allowed on the trails.
Cleveland National Forest
Cleveland National Forest borders Alpine to the east and covers over 460,000 acres of mountains, canyons, and wilderness. From Alpine, you can access trailheads along Alpine Boulevard east and Japatul Valley Road. Three Sisters Falls is one of the most popular destinations. The Lions Tigers & Bears sanctuary is right on the edge of the forest, and several trails in the area pass through oak woodland and grassland that feels nothing like the rest of San Diego.
Louis Stelzer County Park and El Monte Park
Louis Stelzer County Park on Wildcat Canyon Road, south of Barona Resort, draws 1,000 monthly searches. It''s a quieter park with picnic areas and short trails through chaparral. El Monte Park, on El Monte Road near the San Diego River, is another local option with easy walking trails and picnic facilities.
Before You Go
East County trails are hotter than coastal trails. Ten to fifteen degrees hotter in the summer. Bring extra water, wear sun protection, and check fire conditions before heading into Cleveland National Forest during wildfire season. Cafe 67 on Mapleview Street in Lakeside and Janet''s Montana Cafe on Alpine Boulevard are both solid post-hike breakfast spots.
