Sierra de San Francisco: One of the most impressive and unique experiences in Baja California is the cave paintings of the Sierra de San Francisco. This UNESCO World Heritage area concentrates some of the best-preserved and most impressive rock art sites in the world, known as the “great murals.” 400 sites have been recorded in the region and most of the sites remain intact and in good condition. The good condition of the rock art is attributed to the dry climate and remote, inaccessible location. Set in a seies of steep canyons, visitors will find rock cave shelters and huge panels decorated with depictions of human figures as well as marine and land wildlife, painted in red, black, white, and yellow. While the Sierra de San Francisco is home to numerous notable rock art sites, the most impressive site on the whole peninsula is Cueva Pintada. The size of the cave and the durability of the paintings that have survived, make it remarkable. At 100 feet long with more than 40 figures, the site is one of Baja’s best treasures.
