The extraordinary prehistoric rock art of the Sierra de San Francisco is a UNESCO World Heritage Site featuring thousands of paintings depicting humans, deer, fish, and abstract forms in vivid red, black, and yellow. The caves are reached by guided horseback or hiking expeditions from San Ignacio. These 7,500-year-old paintings by the ancient 'Painters' culture are among the finest in the Americas.
The rock art of the Sierra de San Francisco occupies a range of volcanic mesas and deep barrancas in northern Baja California Sur, inland from the oasis town of San Ignacio. Inscribed on the UNESCO World Heritage list in 1993, the site holds several hundred painted shelters attributed to the culture the Spanish missionaries called the Painters, with the oldest work dated to several thousand years before the present. The paintings are executed in red, black, white and ochre on high cave ceilings and overhangs, and depict life-size and larger human figures with raised arms, deer, bighorn sheep, rabbits, whales, turtles and fish, often overlapped in successive layers.
Cueva del Ratón, close to the village of San Francisco de la Sierra, is the most accessible site and can be seen on a half-day outing. The major galleries — Cueva Pintada, Cueva de las Flechas and Boca de San Julio in the Cañón de Santa Teresa — require descending into the canyon by mule or on foot and are visited on one- to three-day expeditions with pack animals, camping at the canyon floor. Cueva Pintada in particular runs for more than a hundred metres of painted rock face beneath a single overhang, and the scale is the thing photographs fail to convey.
Visits are tightly controlled. Every group must be accompanied by a guide registered with INAH, the national anthropology institute, and permits are issued at the INAH office in San Ignacio or through the community in San Francisco de la Sierra. Independent access is not permitted. Tours cost roughly $60-120 USD per person depending on length, with mules, guide, permits and camp meals arranged locally. Touching the paintings and using flash are prohibited.
The approach is a two-hour drive from San Ignacio on a road that climbs steeply onto the mesa, and canyon descents are steep and hot. October through April offers workable temperatures; summer in the barrancas is dangerous. Morning light reaches the overhangs best, and guides time descents accordingly.

When to visit
October through April gives workable temperatures, while summer heat in the barrancas is severe and expeditions are generally not run then. Guides time canyon descents for the morning, when light reaches into the overhangs and the walking is coolest.
Accessibility
The sites are reached by a steep unpaved mountain road from San Ignacio requiring a high-clearance vehicle, and access to the paintings themselves is on foot or by mule down rocky canyon trails. There are no adapted facilities, paths or toilets anywhere in the sierra, and the visit is not possible for wheelchair users or those with significant mobility limitations. Even Cueva del Ratón involves a short uneven walk from the road.
Frequently asked questions
How long does a visit take?
Cueva del Ratón can be seen in a half day from San Francisco de la Sierra. Reaching the major galleries in the Cañón de Santa Teresa requires a one- to three-day expedition with mules and canyon camping.
Can the caves be visited independently?
No. Every visit must be accompanied by a guide registered with INAH, the national anthropology institute, and permits are issued in San Ignacio or through the community at San Francisco de la Sierra. Unaccompanied access is prohibited.
Is photography allowed?
Photography without flash is generally permitted at the sites, and guides will indicate any restrictions. Touching the painted surfaces is strictly forbidden, as skin oils damage the pigment.
Is it worth it for kids?
The short Cueva del Ratón visit works for older children. The multi-day canyon expeditions involve long mule rides, steep descents and rough camping, and are unsuitable for young children.
