Islas San Benito

The group consists of three barren islands, with a total area of 3.899 km2, and is surrounded by rocks and patches of kelp.

Rocas Pinaculo, two steep-to rocks, lie 1.6 km west of Benito del Oeste.

Benito del Centro is low and flat with a hill 82 ft (25 m) high rising near its eastern end.

The vegetation consists mainly of low shrubs and herbs as well as some large cacti (Cylindropuntia prolifera, C. ramosissima[3]).

Birds are moderately abundant due to the islands' barrenness, but Cassin's auklet is rather plentiful at breeding time.
