This short but steep hike yields some panoramic views of north San Diego County and southern Riverside County. The hike sadly loses points due to graffiti (particularly on the summit) and trash, but the scramble up the rocks to the summit is still worth doing if you’re in the area. Expect to use your hands as much as your feet and allow extra time for the descent.
From the parking lot, follow the signed trail up a wooden staircase. The first half of the hike is fairly easy going as the trail winds around the base of Rock Mountain. There are no shade trees but the slope faces west, so if you get off to an early start the sun will be blocked out.
At about a quarter mile, stay straight as a trail branches off to the right. Soon after, take a hairpin left turn and head west, soon arriving at a clearing (about 0.4 miles from the start) where an abandoned car sits.
From here, the hike becomes challenging. Head straight, climbing up a loose, rutted slope and continue your steep ascent for another tenth of a mile. The trail, sometimes faint but usually pretty obvious, appears to dip downhill and fade out at this point. Look for a use trail on the right, heading straight up through the sage scrub, soon arriving at a saddle where you get some striking aerial views of the landscape below. You also see the summit of Rock Mountain on your left.
Head left and follow a thin ridge toward the peak and then pick your way up over the boulders to the summit. Your exact route may vary but you will generally stay on the south side of the peak, keeping it on your left.
On the top, you can sit on any of the jumble of boulders and enjoy an excellent view which on clear days may include the Palomar Mountains and the ocean. You also get a bird’s eye look at Sandia Creek Road, winding its way through the hills below. When you’re done enjoying the view head back down, respecting the steep and loose terrain on the descent.
