Going north to south, Baja California reveals an unexpected face of Mexico: a nature that is wild and untouched, endless beaches of fine sand, a succession of blue water inlets and lagoons, vast tracts of desert punctuated by giant cacti, rugged sierras and dizzying canyons. By way of the highest mountains on the peninsula, this is a journey over a California that is too Mexican to be American, a California that is wild and authentic.
