What to Expect

You'll start from the Cottonwood Spring Oasis parking lot on the park's quieter southern end, where most of the Joshua Tree crowds never bother to venture. The trail shares its opening stretch with the Lost Palms Oasis route before splitting left onto the Mastodon Peak loop. The terrain is classic high desert — sandy and rocky underfoot, fully exposed, with ocotillo and cholla cactus lining the path. The elevation gain is gentle enough that you'll barely notice it until the final push, where an optional scramble up jagged granite boulders rewards you with panoramic views stretching south toward the Salton Sea and the Chocolate Mountains. You'll also pass the ruins of the old Mastodon Gold Mine, a relic from the 1930s that most hikers walk right past. This is the perfect trail for someone who wants a real desert summit experience without committing to an all-day sufferfest.

Safety Advisory

The summit scramble involves exposed granite with real fall potential — skip it if the rock is wet or if you're not comfortable with hands-on-rock scrambling. There's no railing and the drop-off is unforgiving.

There is zero shade on this entire loop. Desert sun reflects off the rock and sand, making the heat feel worse than the thermometer reads. In anything above 85 degrees, this trail becomes genuinely dangerous without adequate water and sun protection.

Pro Tips

Trail Tip

Start at the Cottonwood Spring trailhead rather than the campground — the parking lot is larger and puts you on the trail faster. Cottonwood is about 25 miles south of the main park entrance, so you'll dodge the Twentynine Palms and Hidden Valley crowds entirely.

Trail Tip

Do the loop counterclockwise to hit the peak scramble while your legs are still fresh. The scramble is optional but worth it — it's a short Class 2 boulder move, no ropes needed, and the 360-degree view from the top is the whole point of this hike.

Trail Tip

Pause at the Mastodon Gold Mine ruins on the descent — there's a visible mine shaft opening and scattered tailings that photograph well in low-angle morning light. Pair this hike with a quick detour to Cottonwood Spring itself, a genuine desert oasis with fan palms just steps from the parking lot.
