Though its height of 1,644 feet might not turn any heads, Double Peak offers excellent views on clear days, making it a popular destination among local hikers. The peak can be reached via Discovery Lake or by the short though adventurous route described below. (It can also be reached by driving, but what fun is that?)

Begin by following the Lakeview Trail from the parking lot. The trail heads slightly downhill, following the ridge and providing views of San Marcos. If visibility is good, the Palmoar Mountains can be seen in the distance. Despite the nearby road and houses, this stretch of the trail is pleasantly quiet. The trail weaves in and out of some oak chaparral before reaching an unsigned junction with a use trail 0.6 mile from the start.

Now comes the challenging portion of the hike. The use trail climbs steeply, gaining about 100 feet in 0.1 mile to reach a paved road. Turn left and follow the paved road a few yards to another unsigned use trail, this one gaining 250 feet in 0.3 mile to Double Peak Park. A use trail leads to the smaller, eastern summit while a more established trail gets you to the western peak. Here, you can sit at a picnic table and enjoy a 360-degree view which, given good visibility, can extend to the ocean to the west and the Cuyamacas to the east. Also prominent in the east are Iron Mountain and Mt. Woodson and, much closer, Frank’s Peak and the KOWF-FM radio towers.

After enjoying the view, retrace your steps, exercising caution on the steep and loose descent.

  1. I stopped off to check out this park on my way to a meeting in La Jolla. It’s easy to get to from the freeway, has free parking right outside the gate (gate closes at 8 PM this time of year), nice playground, clean restrooms. All of the trailheads are marked “Hiking Trail.” Duh. Friendly ranger gave me a map. Worth a visit if you’re in the area.
