The Other Side of Bahía Concepción

The first influx of travelers to Baja California followed World War II, thanks
to the creation of the civilian Jeep, the Willys station wagon and pickup, as well as
the Dodge Power Wagon and other four-wheel drive vehicles. Many, if not all the
dirt roads of Baja were soon traveled which opened up the backcountry that
most of Baja was at the time.
Howard Gulick, an engineer with the City of Glendale took it upon himself to
travel and document all the roads and make professional, hand-drawn road maps
of the peninsula. Those logs and maps were published and updated in four
editions and two additional printings of the Lower California Guidebook from
1956 to 1970.
Sadly, Howard’s original, large-scale maps were edited to fit the book, and many
lesser used roads were not included in the published work. Still, Mr. Gulick’s
guidebook maps were the finest maps of the peninsula for many decades, even
though paved roads began to erase the mystery of what was out there.
In 1966, world famous mystery author and the creator of Perry Mason, Erle
Stanley Gardner, was exploring Baja California with a group of associates using
four-wheel drive vehicle, custom made dune buggies, and ATVs. Gardner loved
the desert and Baja California. It offered him an escape from the demands of
Hollywood TV producers. He also utilized helicopters and airplanes to explore and
to shuttle TV scripts back and forth between his Baja camps and Hollywood.

Gardner enjoyed camping on Bahía Concepción and looked across to the other
side asking anyone he could, “what is over there?” He got shrugged shoulders.
That was just no good, he had to find out! The maps of the 1960s showed no road
on the on the 30-mile-long peninsula that creates the bay.
However, if one read all of the Lower California Guidebook, in the chapter called
Places Reached by Sea, Gulick writes: “There is an old road, no longer used, on the
east shore of the bay running out to Punta Concepción, where there is an
abandoned manganese mine.”
Erle Stanley Gardner did not mention the mine but did show the petroglyphs of
Arroyo los Pintados as well as the landing strip his team made so Captain
Francisco Muñoz could land his plane over there and ferry TV scripts and supplies
while Erle and his team were exploring.
The next mention of the other side of Bahía Concepción comes in the 1977
guidebook by Jim Hunter named Offbeat Baja in which he details the 34-mile road
to the manganese mine, which is on the east side of the peninsula, opposite the
entrance of the big bay.
An excellent article by Bob Vinton appears in the November 1991 edition of the
Baja Explorer magazine in which he provides details and color photos of the trip
out to the Gavilanes manganese mine, which employed nearly 7,000 people until
it closed in 1948.
In the 1996 off road guide to central Baja California, Backroad Baja, by Patti and
Tom Higginbotham, the 34-mile road to the tip and mine is detailed. The mystery
would seem to have been solved? Not quite the case! No amount of writing or
photographs and maps can relay the experience of actually driving little used
roads in the wilds of Baja California.
The Baja Extreme Tour at Bahia Asuncion.
In September of 2016, four off road vehicles attempted to reach the end of the
road and here is the story:
Jesse Hansen is an executive chef at a major hotel and oversees the activities of
dozens of people in his kitchen. This requires no lack of skills and planning on a
daily basis. Jesse owns two four-wheel drive vehicles and off roading is a way for
him to unwind and have fun. The Baja Extreme Tour of 2016 had been planned for
months and with several modifications to the original route, which I suggested to
get the maximum fun over the 11-day adventure, going to the end of the
Concepción Bay peninsula was one of the activities planned by Jesse that would
The Concepción peninsula road, southbound.
Riding with Jesse in his Toyota Land Cruiser wagon was Hollywood actor and
model Marland Burke. Three more vehicles were part of the Baja Extreme
caravan. A Toyota 4Runner with Nick Helton an engineer and Christine Joy a
physician assistant, a Toyota FJ Cruiser with ‘Ham’ an electronics genius and his
sister Jerry, and my Toyota Tacoma with Pat Malone a real estate investor and I,
as the tour guide.
On Day 5 of the 11 day Baja Extreme tour, we drove from San Ignacio to Bahía
Concepción and check in with Mark, Olivia, and Nathan at Playa Buenaventura to
hear of any reports from the other side. Mark suggests we avoid the mud beds on
the first access road (Km. 76) and go another mile south (nearly to Km. 74) for a
dry road to the other side. We enjoyed a fabulous meal created by Olivia and
head on down the road. Once off the highway, we deflate our tires about 30% for
improved traction and reduce possible rock punctures.
While we did not reach the point that evening, what we saw and experienced the
two days we were on the other side, left a lifelong memory for us of how extreme
Baja can be! The following road log describes the road we took exploring the
other side of Concepción Bay:
The road along the east shore of Bahia Concepción.
0.0 Highway One near Km. 74. Well used road goes east and northeast.
0.4 Pass to the right of a ranch, continue northeast.
1.0 Junction with pre-1970 main road between Tijuana and La Paz. Road heads
3.7 Fork, leave old Baja main road and take left branch going northeast.
4.7 Junction with mud road from Km. 76. Head east.
5.5 Fork, go left (north) to head up the Concepción peninsula.
6.3 Come alongside the shore of the bay.
7.2 Mudflat. The route from/to Arroyo Tres Marías (3 miles) is to the right, near
the base of a hill. Road to Punta Concepción continues north. Curve around to the
right of any water or deep mud. The 4Runner got stuck here going straight, the
rest of us easily went around and pulled him out.
9.8 Three cardón cactus stand side-by- side, next to the road, marking the south
bank of Arroyo los Pintados. The access to the painted cliffs (about 1.6 miles) and
our route to Arroyo Tres Marías 4x4 trail (see below) is here.
15.2 Road heads uphill and away from coast. Fence gate (if closed, keep it closed
Driving through arroyo Tres Marías.
16.8 Road turns downhill and returns towards coast.
19.7 Road nears flat area of Punta Amolares (where we set up camp at midnight).
The road on north becomes less traveled and is overgrown by thorny bushes and
trees. Only motorcycles recommended beyond here.
25.6 End of road for us, deep gully washout ahead.
Arroyo Los Pintados/ Tres Marías side trip from Mile 9.8, above:
0.0 Drive east in sandy arroyo, away from coast.
0.7 Fork. Los Pintados is left fork and the canyon entrance is a mile away. We take
the right fork and soon find an old road leaving the arroyo to the right.
1.4 After a difficult gully crossing, the old road drops into Arroyo Tres Marías and
we turn left to follow it. Eventually coming to running water, we are encouraged
to follow it further.
1.9 An old road to the right (hidden by brush) is how we left the area and avoided
the gully crossing. It is 3 miles to the coast road junction at Mile 7.2.
3.6 End of road, former Rancho Tres Marías ruins. Spring ahead and to right in
side ravine with fence along right side.
