Jacumba Wilderness

The Jacumba Wilderness covers about 31,000 acres of low desert against the border, roughly thirty miles west of El Centro. It is a land of broad, flat plains broken by hills of stacked granite boulders, drained by Carrizo Creek and framed by the Jacumba and In-Ko-Pah Mountains. Ocotillo whips grow on the flats and native California fan palms cluster in a few hidden seeps, the only real green in an otherwise sun-baked landscape.

The wildlife is the quiet prize. The endangered Peninsular bighorn sheep, a small and shy population, still moves through this rocky country, and golden eagles ride the thermals overhead. Mule deer, jackrabbits, and the odd flat-tailed horned lizard round out the cast. Because the area is protected wilderness, there are no roads, no bikes, and no motors inside it, so anyone who ventures in does so on foot and on the desert's own terms.

The single most famous spot in the Jacumba country is the Valley of the Moon, a natural playground of enormous granite boulders seamed with cracks and stacked into arches, chambers, and passageways. For decades San Diego climbers and scramblers have called it one of the best bouldering grounds in the region, a place to spend a whole day threading between rocks the size of houses.

Getting there is half the adventure. The valley sits a few miles east of Jacumba Hot Springs at the end of a rough, potholed gravel road that punishes ordinary cars, so most people come in a high-clearance or four-wheel-drive vehicle. There are no signs, no rangers, and no facilities, only the boulders and the silence, which is exactly what draws people who love it.

For all its emptiness, this stretch of desert has been the great obstacle three separate generations of travelers had to beat. In the wagon and early auto days, teams strained up the brutal Mountain Springs grade just east of here, where a stage station once helped haul wagons over the divide, and later the Old Highway 80 corridor carried the first road travelers through the boulder gorges.

Then came the railroad. Just north of the wilderness, in Carrizo Gorge, the San Diego and Arizona Railway earned its nickname, the Impossible Railroad, by blasting eleven miles of track through sheer canyon wall, with seventeen tunnels and a string of wooden trestles clinging to the rock. Its golden spike went in during 1919, and for a few decades the line made this remote corner reachable and gave Jacumba its heyday as a hot-springs resort town.

The most recent crossing is the border itself, whose wall and roads now run along the wilderness's southern edge. The town of Jacumba was once one community with Jacume on the Mexican side, split when the border hardened and the local crossing finally closed in the 1990s. Stand out in the boulders today and you can read all three eras at once: the wild desert, the human works that tried to conquer it, and the ways the town rose and faded with each.

The wilderness is reached off Interstate 8 near the In-Ko-Pah and Jacumba Hot Springs exits, with rough dirt roads leading in from the freeway and from County Route S-2 near Ocotillo to the east. None of the approaches are gentle, so a high-clearance vehicle and a full tank are essential, and there are no services once you leave town. Fuel, food, and water are all in Jacumba Hot Springs or Ocotillo, so stock up before you head in.

Come in the cooler half of the year, roughly late fall through early spring, and treat the desert with respect: carry far more water than seems necessary, tell someone your plans, and expect little to no cell signal. Because the area hugs the international border, Border Patrol activity is a normal part of the scene. Do all that, and you get one of the emptiest, strangest, most rewarding corners of California, a place where the desert still wins and the boulders go on and on.
