   HIKING @ JOSHUA TREE NATIONAL PARK: 
SKULL ROCK-JUMBO ROCKS LOOP

WEDNESDAY, MARCH 23

 
"It began long ago when rain drops accumulated in tiny depressions and started
to erode the granite.  As more rock eroded, more water accumulated, leading 
to more erosion until, as time passed, two hollowed-out eye sockets
formed and the rock began to resemble a skull. ."

This was my seventh of eleven different trails to hike at Joshua Tree this week and it ended up being my third or fourth favorite.

I hiked it solo on Wednesday and went back a second time the next day with Jim because I knew he'd like the unusual "skull" and the undulating trail through some spectacular rock scenery. Photos in this entry are from both hikes.

This is a very popular trail, particularly right at Skull Rock, which is just a few yards off busy Park Boulevard, the main east-west route through the national park.

The skull is at the NE end of the loop. The area stays congested and by the middle of the morning, it can be difficult to find a parking spot. I took the next shot from across the road the second time I hiked the trail:

It's hard to see if you're looking at this picture on a small screen but at least a dozen people were around the skull right then.

Fortunately, many people just hop out of their vehicles and stay only a few minutes to take pictures of Skull Rock, then leave. If you want to hike all or part of the trail, you can also access the trail from two places in or across the road from Jumbo Rocks Campground, through which this loop passes. Just don't park in someone's camp site.

Here's a diagram of the trail from one of several signs along the loop:

I added the red dot to indicate the place I parked both times I hiked the trail, right near Skull Rock.

If you're looking at this entry on a small phone or tablet screen and can't read the trail description or distances on that sign, here's the scoop:

The undulating, well-marked trail loop is 1.7 miles long. There are three segments: 1) a half-mile nature trail with signs about the flora and fauna between Skull Rock and Jumbo Rocks Campground on the south side of Park Boulevard; 2) half a mile through the campground itself on paved roads; 3) 7/10ths of a mile on the other (north) side of Park Boulevard, which was the most interesting segment of the trail to me.


Part of the Skull Rock nature trail on the south side of the park road

On my solo hike on Wednesday I arrived at the parking area closest to Skull Rock about 9 AM and hiked the whole loop in the clockwise direction.

On that hike I ended up with 2.2 miles because of deliberately going off into some gullies and up on rocks to explore further. My GPS recorded 716 feet of elevation gain and loss at 4,123 to 4,278 feet altitude.


An easy part of the trail on the north side of the park road

The next morning Jim and I stopped at Skull Rock fairly early so we could see it and take pictures with few to no other people there. Then we drove farther west to hike the loops at Barker Dam and Hidden Valley.

On our way back east on the park road we stopped to do the section of the Skull Rock loop I liked the best through the boulders, slots, and washes -- the northern part of the trail across from Skull Rock and the campground. It was less crowded at that time of day than the trail between the skull and the campground.


Fun with narrow slots to slither through

Jim began his hike across from the campground entrance and hiked 7/10ths of a mile NE toward Skull Rock, the same direction I hiked it the previous day. I drove ahead to Skull Rock, parked (lucked out on that!), and walked back along the trail toward Jim. When we met, I turned around and walked back to the car with him.

There weren't a lot of people on the northern section of the trail either afternoon even though Skull Rock itself had plenty of company both times.

The Park Service rates this trail as easy, and I agree with that but I'm surprised, based on some of its other ratings, that it considers this trail easier than the very flat Wall Street Mill Trail.

The Skull Rock loop undulates through some soft sandy washes and narrow slots between boulders on the north side of the road. There are also some rocks, roots, and rock steps. It's not wheelchair or stroller accessible except on the paved roads through Jumbo Rocks Campground.

SKULL ROCK TO JUMBO ROCKS CAMPGROUND

These are some other photos I took in this segment of the loop on my first hike, all on the south side of the park road, going clockwise, starting at Skull Rock and ending in the campground. (See trail diagram above.)

Let's start with some other photos of the eponymous Skull Rock taken at different times of day:

 


Here's an unknown person to give some perspective re: the size of Skull Rock.

The skull is a little creepier the closer you get:

 

 

OK, let's hike, heading southwest toward the campground.

I consider this section to be more of a nature trail because of all the signs re: the desert ecosystem. Although it's undulating, this half mile is significantly easier to negotiate than the trail on the other side of the road.


The trail sometimes goes through soft sand in washes on both sides of the road.

 


Me and my shadow;  the sign describes the delicate balance of the ecosystem, describing how the 
California Juniper tree and desert wildlife are dependent on each other for their mutual survival.

 


This is the only place in the park where I remember seeing this kind of
unusual rock "stripe" between the boulders. I don't know how it was formed.


Here's another conundrum:  Why are the boulders
on the left rounded and the ones on the right pointed?


Desert Paintbrush:  you can't miss the bright red in
an otherwise relatively colorless desert setting!

Just before half a mile the trail makes a wide S-turn on the ridge above the Jumbo Rocks Campground and drops down past a clump of Mojave yucca in bloom to the paved road going through the campground:

 

 

It's another half mile on the campground road past the small but attractive campsites set among the boulders, some restrooms if you need them, and out the other side to the main park road:

Above and below:  This campground has about 100 sites and they were full all week.

After walking through the campground you'll come to a trail that crosses the main park road. The Skull Rock loop continues on the other side:

THE NORTHERN SEGMENT OF THE TRAIL

Ah. Now we're over to the part of this loop that I like the best because it's less traveled, more wild . . .  and therefore more interesting to me.

Let's head 7/10ths of a mile northeast, back to the skull. Get ready for some awesome rock formations, narrow slots, wide panoramas, deeper washes, and higher ridges. Here are some  representative pictures in addition to those shown earlier, in order going clockwise on the loop:

 

 

There are a lot of rock steps on this side of the loop:

 

When the trail is on the ridge in the next two photos, you can see the park road for a little while.

I didn't even notice it while hiking because I was too busy looking at the fabulous scenery and watching my footing!

 

Most of the time, rocks and hillsides block the view of the road and the trail feels remote.

There are so many cool boulders, big rock formations, and massive areas of bedrock along this trail, like in the next photo, that would be really fun to explore off-trail for hikers with more time than I had. That's one good reason to stay in a nearby campground rather than outside the park.

The trail repeatedly roller-coasters down into washes or gullies and back up to ridges:

 

 

 

In the last quarter mile the trail goes through a soft, wide wash and comes to a fun part of the loop with a slot canyon with several boulders to maneuver through. I showed Jim going through the most narrow one farther up in this entry.

 

 

 


"X" marks the spot.

View across the road (can't see it here) to Skull Rock from the last ridge; I gave the skull a red dot.

See why I like that trail so much???

And that's only a few of the scenes along the way. There's a lot to enjoy along this part of the loop, even if you don't explore and climb the rocks.

Next entrythe Split Rock Loop Trail with a side trip to Face Rock (hmmm . . . Skull Rock and now Face Rock??)

Happy trails,
