Arco del Oeste is a rock formation in Grand Theft Auto: San Andreas at the northwestern edge of Bone County, San Andreas, just south of Valle Ocultado and west of Las Brujas and El Castillo del Diablo. It juts into Sherman Reservoir, providing pristine views of nearby Sherman Dam to the south, and features a natural arch and a mesa, an abandoned mining facility, wooden shacks to the top, and a small dock on the southwestern side.
Its name translates roughly from Spanish as Arc of the West, apparently taking its name from its natural arch and location towards neighboring Tierra Robada.
Prominent appearances in missions

- It is featured once again in the Las Venturas strand of missions, wherein Carl is tasked yet again by The Truth to rescue two drug addled people, later named as Kent Paul and Maccer.
