If you’ve got a few calories to spare, you want all the views, and you wish to unleash the hurt on your quadriceps, I have a great hike for you. The highest point of the Palomar Mountains, dubbed — wait for it — High Point — is a great place to get abundant doses of all of the above. The views here are so good that the Forest Service operates a fire lookout tower that, legend has it, once spotted a fire burning in Santa Barbara County 200 miles away.
High Point occupies a rounded knoll on the eastern edge of the gently rolling range. The route to the top starts from the base of the mountain and wastes no time in climbing. The temps on the east side of the range can be terrifically hot during the summer months, and even though it’s always temperate up top, you probably will want to sit this one out during July and August.
The mountain is also a good spot for backpacking. The Palomar District of Cleveland National Forest recently abandoned their lack of red tape backpacking policies, meaning you now have to fill out a permit request, fax it in to the Palomar District, and wait for your permit. There are a pair of seasonal water sources that might allow refilling, and there are a few different campsites at two spots on the mountain for camping.
From the Oak Grove Fire Station, find and follow the sign indicating the Oak Grove Trail. This trail will cross a seasonal creek and then begin a sharp ascent along a ridge, crossing back and forth over an old fire break. This is the toughest part of the hike, as the Oak Grove Trail gains about 1500 feet over 1.8 miles. Initially, the trail climbs on the sunny side of the slope, which gets warm in a hurry. At 1.5 miles, the trail crosses over onto the north slope, where shade from dense chaparral will provide a bit of relief from the heat.
At 1.8 miles, the trail reaches the Oak Grove Fire Road. East of this spot, the road is gated and enters private property. Turn right to enjoy a more reasonable grade as the road follows a ridge for another 1.5 miles to another junction with High Point Truck Trail. All along this stretch of trail, impressive views over the Inland Empire culminating in the twin giant of Mt. San Gorgonio and Mt. San Jacinto will provide interest and a bit of inspired awe as you work your way uphill.
At 3.4 miles, you’ll pass the junction for High Point Truck Trail, keeping left to continue climbing. Just past the junction, you’ll see a large, solitary pine tree at the base of the ravine. A concrete cistern lies hidden in some shrubs. This cistern is a collecting tank for a nearby spring. You can lift the lid off the top and pull water from within using a pump filter. You will definitely want to filter this water AND treat it chemically, as the water looks very unappealing.
High Point Truck Trail makes a sharp bend to the southeast as it progress toward the headwaters of Cottonwood Creek at Deer Flats. You’ll know you’re close to Deer Flats due to a large grove of bigcone Douglas firs that cluster outside a small gentle valley. This little valley is well-shaded by black oaks and the occasional incense cedar. You’ll be able to see the High Point lookout tower across this valley and atop a rounded hill.
At the 5 mile mark, you reach a junction with the Palomar Divide Truck Trail. Keep right here and follow the trail as it makes a wide switchback through groves of black oak whose golden leaves shimmer in the fall. As the trail begins to bend around the north flank of High Point, you encounter a gated side road leading away on your right at .5 miles. This side road will lead you down to Sourdough Spring, a seasonal water source that may provide enough water to let you tank up. This water also needs to be filtered and treated with chemicals as it becomes stagnant and riddled with algae when the spring does not have a robust flow.
At 6.1 miles, you’ll reach a final gate with a dirt road leading circuitously to the summit. As you wrap around the western face of High Point, the view that has been obscured by the mountain’s bulk finally comes into focus. You will immediately notice the gleaming white domes of the Palomar Observatory. Soon after, you’ll take in the rolling, forested crests and tranquil valleys that dominate the highlands of the Palomar Mountains. The view southeast reveals the sprawling breadth of San Jose de Valle as it spreads out toward the Volcan Mountains.
Finally, a 6.5 miles, you reach the flat summit. The High Point lookout tower dominates the summit, which also includes a few support buildings, a picnic bench, a cabin foundation with some planted sequoias, cypresses, and sugar pines, and a porta-potty. The cluster of rocks just southeast of the lookout is the true summit, and from here you can enjoy the view ranging from southeast to northwest.
From this spot on a clear day, you can test your geography knowledge by attempting to identify as many of the following spots as possible. From the northwest ranging to the southeast: Mt. Baldy, Mt. Baden-Powell, Santiago Peak, Lake Elsinore, Santa Margarita Peak, Agua Tibia Mountain, Boucher Hill, Birch Hill, Mendenhal Valley, Barker Valley, Otay Mountain, El Cajon Mountain, Viejas Mountain, Lyons Peak, Cuyamaca Peak, Middle Peak, Stonewall Peak, North Peak, the Laguna Mountain Escarpment, the tip of Granite Mountain, Whale Peak, Mesa Grande, Volcan Mountains, San Felipe Hills, Pinyon Ridge, Hot Springs Mountain, Dawns Peak, and Toro Peak.
Leave your bouldery perch and stroll over to the eastern side of the summit, and see if you can spot the following, ranging east to northeast: Santa Rosa Mountain, the Desert Divide, Thomas Mountain, Mt. San Jacinto, Cahuilla Mountain, Mt. San Gorgonio, the Rim of the World, before returning finally to Mt. Baldy. It’s not hard to understand why they put a lookout tower here.
The return route re-traces your way up to the top. If you’re backpacking, a nice sheltered spot can be found if you return back to just before the junction of High Point Truck Trail and Palomar Divide Road. A side road heading southeast (a continuation of Palomar Divide Road leading to Barker Valley) will take you through a grove of black oaks to a bare, flat spot that’s perfect for camping.
The Oak Grove Trail is steep, often eroded, and quite the cardio experience. Once you reach the Oak Grove Truck Trail, it's all smooth, well-graded roads for the remainder of the hike.
The nearest campsite is across the street from where you'll park at Oak Grove Campground.
From I-15 in Temecula, exit on Highway 79 South toward Warner Springs. Continue South through Temecula and the village of Aguanga for 23.7 miles to the village of Oak Grove. Turn left into the Oak Grove Fire Station. A small parking lot lies adjacent to the trailhead.
With recent wildfire damage and ongoing waves of COVID-19 infections and restrictions, National Forest, National Park, and other public land closures, restrictions, or social distancing guidelines may be in-effect.
If infection rates are on the rise, please do your best to remain local for your hikes. If you do travel, please be mindful of small gateway communities and avoid as much interaction as you can. Also remember to be extra prepared with supplies so you don't have to stop somewhere outside your local community for gas, food, or anything else.
Please be sure to contact the local land management agency BEFORE you head out, as these conditions are likely to change without enough notice for us to fully stay on top of them. Thanks, and stay safe!
