Overview
Starting from Cottonwood Spring, along the Lost Palms Oasis Trail, Mastadon Peak is another fantastic, relatively short, family friendly hike within Joshua Tree National Park. Although the hike is short rounding out at between 2.5 and 3 miles, it is just long enough to get a good workout in and really make it feel like an actual hike. While Mastadon Peak still gets a lot of traffic it is not nearly on the level of the trails along the Park Boulevard road. Early morning hikes here usually result in a fairly large amount of solitude. For those looking for a bit more of an adventure they can extend their hike, following the trail to Lost Palms Oasis, making for a nearly 8 mile hike.
Along the Mastadon Peak trail visitors will encounter phenomenal boulders and rock structures as the trail winds through them towards the summit of Mastadon Peak and then a short distance to the old Mastadon Mine. A short scramble leads, that may not be for everyone, leads to the top of Mastadon Peak. Exceptional views of the lesser visited southern portion of the park present themselves here. For those not willing to scramble up to the summit, don’t hesitate to explore the other areas along the nearby rock faces that also offer fabulous views. Many will decide to hike this trail as a loop but as I find the section of trail just before the Mastadon Peak Summit the most, I prefer to do it as an out and back to revisit what I consider the best portions of the trail.
Trail Description and My Story
My wife and I were super excited to hit the trails in Joshua Tree National Park over a few days. The Mastadon Peak Trail was one that had consistently been closed over the years when we had visited and subsequently we had never had the opportunity to enjoy it. We were anxious to finally hike it on this day. We didn’t get our typical early morning start but were still able to set off from the trailhead by about 10 AM with few other hikers in sight.
This would be the perfect trail for us on this day, as my wife, Ryan, was nearing her sixth month of pregnancy. We didn’t want to do a super short hike, so the approximately 2.5 mile trail seemed just right for this morning and would get us ramped up for the longer Willow Hole trail that we would be treking the following day.
Parking Area to the Junction With the Mastadon Peak Trail
Leaving the parking area we immediately (.1 mile) arrived at Cottonwood Spring. Although a small area, this is a beautiful section of the trail, filled with California fan palms and cottonwood trees.

After the Oasis the trail turned sandy and a wide and obvious trail. The trail is rather flat here and we enjoyed this leisurely section. After reaching a sign stating that the Mastadon Peak Trail was .7 miles away, we began a mild climb with some stairs. Ryan was doing exceptionally well and our pace was remaining fairly quick. Following the trail arrows we reached the signed trail junction for Mastadon Peak.
Making a left at the trail junction and leaving the Lost Palms Oasis Trail, we now began a steady climb towards Mastadon Peak. This was our favorite section of the trail as the hike now proceeded through the rock formations. An excellent section with stairs carved into the rock is a defining spot along the trail.


The trail began to circle back and forth before flattening out just before the peak.
Reaching Mastadon Peak and Visiting the Mastadon Mine
As Ryan made her way towards Mastadon Peak, I elected to head right and up the separate rock structure. Hikers should make sure to explore the area around the peak, as there are some sections just as worthy of visiting as the actual summit of Mastadon Peak.

After a bit, Ryan joined me and we descended and continued a very short distance to the Mastadon Mine. There are two areas of the mine and they are rather neat to visit. The main mine shaft goes down 50 feet and has been caged off to prevent people from entering.


For those wishing to finish the loop, which most do, they can merely follow the well marked path back towards the start of the trail. On this day, we choose to retrace our steps and revisit our favorite sections of the trail. This is a great trail with minimal effort but still offers just enough to get a reasonable workout.
