1. Hot Springs Mountain (6,533 ft)
Hot Springs Mountain is the tallest peak in San Diego County and one of the most rewarding hikes you can take locally. Located near Warner Springs on land managed by the Los Coyotes Indian Reservation, this hike requires a permit and some planning, which helps keep crowds low.
The most common route is about 10 miles round trip with steady elevation gain. The trail starts in forested terrain and gradually climbs through ridges with wide-open views. While there aren’t many dramatic features along the way, the sense of scale and isolation makes this hike feel like a true mountain adventure.
Cooler months are ideal for tackling Hot Springs Mountain, as shade is limited in some sections. The summit delivers sweeping 360-degree views and a huge sense of accomplishment.
2. Cuyamaca Peak (6,512 ft)
Cuyamaca Peak is the second-highest point in the county and one of the most accessible tall peaks to hike. Located in Cuyamaca Rancho State Park, this summit is popular thanks to well-maintained trails and a relatively gradual climb.
Several routes lead to the top, with the most common being around 7 to 8 miles round trip. The trail winds through oak and pine forest, making it one of the shadier and more comfortable summit hikes in San Diego. In winter, snow is possible, which adds a rare alpine feel.
The summit is marked by a stone monument and offers panoramic views across the mountains, desert, and even the coast on clear days.
3. Palomar High Point (6,140 ft)
Palomar High Point is the highest elevation on Palomar Mountain and one of the more demanding hikes on this list due to its length. Located within Palomar Mountain State Park, this hike feels more like a backcountry trek than a typical day hike.
Depending on the route, hikers can expect a long out-and-back (~13 miles) with significant elevation gain spread over many miles. The trail passes through forested terrain and quiet stretches that see far fewer hikers than popular Palomar spots.
This hike is best suited for experienced hikers looking for an all-day adventure. Cooler temperatures at elevation make it a good option even when lower-elevation hikes feel too warm.
4. Stonewall Peak (5,730 ft)
Stonewall Peak is one of the most popular summit hikes in Cuyamaca Rancho State Park — and for good reason. Located near Paso Picacho Campground, this hike packs a big payoff into a relatively short distance.
The trail is about 4 miles round trip and climbs steadily through rocky terrain with expanding views as you gain elevation. While shorter than other peaks on this list, the elevation gain makes it feel challenging, especially on warm days.
At the summit, hikers are rewarded with dramatic views over the surrounding mountains, desert, and Lake Cuyamaca. It’s a great option if you want a true summit experience without committing to an all-day hike.
5. Villager Peak (≈5,771 ft)
Villager Peak is a remote and rugged summit located in Anza-Borrego Desert State Park. This is not a casual hike — routes vary, navigation skills are required, and conditions can be extreme depending on the season.
Hikes to Villager Peak often involve desert terrain, steep climbs, and long distances with little shade. Because of this, it’s best tackled in cooler months and only by experienced hikers comfortable with route-finding.
The reward is a rarely visited summit with expansive desert views and a strong sense of solitude. Villager Peak is ideal for hikers looking to explore San Diego County’s wildest and least-traveled terrain.
Final Thoughts
The tallest peaks in San Diego County prove there’s much more to the region than coastal hikes. Whether you’re chasing summits, training for endurance, or working through hiking challenges like the 6 Pack of Peaks, these mountains offer some of the most rewarding experiences in Southern California.
As always, plan ahead, check conditions, and hike responsibly — these peaks demand respect, but they give back in unforgettable views and serious accomplishment.
