Dive sites in Costa Rica

Bajo del Diablo is an expansive submerged volcanic rock formation characterized by dramatic underwater pinnacles, massive boulders, and deep canyons. Positioned offshore in the Pacific waters of Costa Rica, currents wash past the rocky ridges, attracting dense schools of pelagic fish and resting reef predators in the cuts between stone towers.

Bajo del Diablo stands out as one of the hallmark submerged rock formations off Isla del Caño. A sprawling network of basalt peaks, boulders, and valleys rises from the sea floor, creating dramatic canyons and corridors where pelagic species congregate. Divers drift past rock walls while massive schools of fish swirl in the blue above, frequently joined by passing elasmobranchs cruising the oceanic currents.

Situated off the coast of Manuel Antonio, this site features rugged volcanic rock formations cut through by distinct sand channels and rocky canyons. Divers follow the natural corridors where marine animals rest out of current, exploring boulder crevices and small overhangs.

Located off the coast of Manuel Antonio, El Acuario is a volcanic rock formation surrounded by sand flats and scattered boulders. Divers navigate rocky channels and swim-throughs where Pacific reef species shelter from the surge. Schools of grunts and snappers circle the high points of the reef, while resting whitetip reef sharks and rays are frequently discovered along the sandy bottom.

El Toro is an exposed rocky reef system situated off the coast of Manuel Antonio. Massive volcanic boulders and fragmented rock slabs create a rugged underwater landscape characterized by narrow cuts, swim-throughs, and sandy channels. Divers frequently encounter resting bottom-dwellers tucked beneath ledges, while pelagic species cruise through the open water column around the formation.

Situated off the coast of Manuel Antonio, this submerged volcanic rock formation features an undulating underwater ridge flanked by rocky boulders, crevices, and sandy patches. Divers drift along the structure watching for bottom-dwelling predators and pelagic visitors sweeping in from open water.

Situated within the volcanic archipelago of the Catalina Islands off Guanacaste, this site features sprawling rock formations interspersed with sandy channels and rubble plateaus. Pacific currents bring nutrient-rich waters that fuel pelagic encounters along the deeper edges of the boulders. Divers typically navigate between large submerged outcrops while scanning the blue for passing rays and inspecting crevices for sleeping sharks.

Located in the northern sector of the volcanic archipelago off Guanacaste, this offshore site features steep volcanic rock pinnacles, boulders, and rubble channels exposed to the open Pacific. Divers drift past rock walls and over submerged plateaus where pelagic animals gather in the nutrient-rich currents. Surge and strong thermoclines are common around the outer rock edges.

Located off the coast of Isla del Caño Biological Reserve in the Pacific waters of the Osa Peninsula, Paradise is a volcanic rock reef and pinnacle formation. Divers descend along submerged rock ridges where pelagic fish congregate in strong numbers alongside Pacific reef species.

Located off the central Pacific coast of Costa Rica near Manuel Antonio, this site features submerged volcanic boulders and rocky shelves layered with sea fans. Schools of pelagic fish patrol the open water above the rocky outcroppings, while crevices and overhangs provide shelter for benthic marine life. Surge can build along the exposed point, though conditions remain accessible during the calm dry-season mornings.

Situated within the protected waters of Caño Island Biological Reserve off the Osa Peninsula, this dive centers around a volcanic cavern carved into the reef. Divers hover outside the wide entrance to watch whitetip reef sharks resting on the sand floor inside. Surrounding volcanic boulders and rocky ridges host dense aggregations of pelagic fish and patrolling stingrays, while surge gently pushes through the channels.

Situated along the rocky coast of Manuel Antonio, Starfish Garden is characterized by volcanic rock formations that slope gradually into sandy plains. The seabed features scattered boulders encrusted with barnacles, hard corals, and sea fans. This sheltered site serves as a frequent spot for open water training and relaxed second dives, offering easy navigation along the reef edge.

El Ancla, or The Anchor, is situated off the protected waters of Isla del Caño Biological Reserve. The site gets its name from a historic ship anchor resting along the rocky substrate and sandy channels. Volcanic boulders, soft corals, and scattered rocky ledges create shelter for resting reef sharks, foraging sea turtles, and large schools of coastal pelagics sweeping in from open water.

Located off Isla del Caño in the Pacific waters of southern Costa Rica, The Arch features a distinctive volcanic rock formation shaped like a doorway. Divers frequently encounter whitetip reef sharks resting on the sandy floor beneath the rock overhangs, while large schools of grunts and snappers circle the structure. The surrounding hard coral gardens and scattered boulders provide shelter for moray eels and sea turtles moving along the current.

Situated along the protected slopes of Isla del Caño, The Garden features rocky volcanic structures intertwined with patches of hard coral and white sand channels. The shallower depths allow ambient light to illuminate schools of reef fish congregating over massive boulder formations. Whitetip reef sharks regularly rest along the sandy margins, while turtles graze on algae-covered volcanic shelves.

Situated off Isla del Caño on Costa Rica's Pacific coast, The Lighthouse (El Faro) features a seabed of massive volcanic boulders, rocky terraces, and hard coral outcroppings. Currents sweep past this exposed point, attracting large pelagics and schooling fish. Divers descend along the rock slope to observe sharks resting on sandy patches between the volcanic formations.
