Finding Petroglyph Park
Article and photos by David Kier
The Magic Peninsula of Baja California never ceases to amaze with the fun and interesting sites to be
seen and experienced.
Using the Baja Cactus Motel in El Rosario as a base, we made a loop trip in the country to the northeast.
It had been something I wanted to do ever since I learned about a road in 1973 that wasn’t on any of my
maps. The road was used for the 1973 Baja 500 in order to avoid the new highway construction around
El Rosario. It has since been used a few times by SCORE for Baja races.
I opted to run the 105 mile loop counter-clockwise, and it was a perfect way to go. In recent years of
wet weather, the El Socorro side of the road is used more by motorcycles than 4 wheel drives. A high
ground clearance 4WD with locking differential or traction control is recommended for travel beyond
Mile 26 and especially beyond Petroglyph Park.
Top your gas tank in El Rosario and set your trip odometer to 0 at the Pemex. Take Highway 1
southbound for 28.5 miles and turn left at the restaurant between Km. 103 and 104 (may be signed ‘Los
Martires’). Reset odometer to 0 upon leaving Highway 1.
Just north of the restaurant is a long clearing that was once the ‘El Arenoso’ airstrip, used during
highway construction, back in 1973. The military has installed ditches on the runway to discourage its use. The road
passes several copper mine pits for a few miles before crossing a rare desert river! We saw many ducks
there in the summer.
Some of the best boojum (Cirio) forests in Baja are along this road... wonderful scenery! The discovery of
petroglyphs where we parked for lunch was just a great Baja moment. A natural spring starts a creek at
this spot, as well. Beyond Petroglyph Park, the road really deteriorates and may not be passable to
larger vehicles. It is 20 difficult miles from Petroglyph Park to Highway 1 at El Socorro. Simply go back if
the road ahead is gone or if you aren’t sure. A companion vehicle would be wise in this area.
