About this site
Quast Rock sits just off San Diego's coast in the Pacific Ocean, offering divers a vibrant underwater experience. The site features rocky reefs teeming with colorful marine life, including garibaldi, calico bass, and occasional leopard sharks. Visibility varies but often reaches 30 feet, with mild currents making it suitable for all skill levels. The rocky formations create swim-throughs and crevices to explore, while sandy patches host bat rays and halibut. Water temperatures range from 55-70°F depending on season. This easily accessible shore dive provides a great introduction to Southern California's coastal ecosystem.
