Hike Mastodon Peak
What to Expect
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
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.
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.
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.
