Antofagasta offers a varied mix of reef, wall, kelp forest, cave and wreck diving across a range of skill levels. Kelp-draped walls and drop-offs define many sites, while the Maria Elizabeth Wreck and Vapor Lima add wreck diving to the roster. Green Sea Turtle and Seahorse are reliably observed across many sites, and Eagle Ray, Bottlenose Dolphin and occasional Whale Shark appearances raise the stakes on deeper dives. Water stays cool year-round, so exposure protection is always worth planning carefully. Shore entries suit beginners, while boat-access sites like El Buey and Pared Sur reward more experienced divers.

Green Sea Turtle and Seahorse are observed across the majority of sites and are the species you are most likely to encounter. Eagle Ray and Bottlenose Dolphin are also commonly sighted, while Grey Reef Shark and Whale Shark appear on occasion. Hermit Crab, Sea Urchin, Anchovy and Sponge are found at virtually every site and form the backbone of the reef community.
Several sites are rated beginner-friendly, including The beach, The Abyss, The Moai Trail and Colin's Double Strike. Most of these are shore-entry dives, which removes the added complexity of boat access. The Vapor Lima wreck is also beginner-rated and sits very shallow, making it a good introductory wreck experience.
Shore-entry sites such as Anemone Wall and Jardines de Copeton are generally more accessible and cover a good range of terrain including walls, reefs and kelp forest. Boat-access sites like El Buey, Pared Sur and El Acuario de Santa Maria tend to sit deeper and are rated intermediate or advanced, rewarding divers who make the trip offshore with more dramatic topography and a greater chance of pelagic encounters.
There are several dive operators active in the region, including Centro de Buceo Océano, Buceo Oceano, Escuela de Buceo Sub-Aqua and Escuela de Buceo Magallanes. Between them they cover both shore and boat diving, so it is worth contacting a local operator to match your skill level and target sites before you arrive.
