A group of guests walk along a dry arroyo on the island of El Carmen, in Baja California Sur, Mexico. The vegetation consists mostly of cacti, plus some riverine trees, like palo verde and palo blanco.

Winter rains have not come to the region yet, probably due to the "Ni¤a," following the "Ni¤o" of winter 1998-1999. El Carmen has quite a few endemic plants and animals, among them the El Carmen giant barrel cactus.
