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.

Situated off the southernmost tip of Costa Rica's Osa Peninsula, Matapalo Rock is an isolated volcanic formation battered by open Pacific swells. Submerged boulders and rocky ridges slope down into sandy troughs where pelagic species intersect with reef dwellers. Water movement around the rock can be brisk as tides pull water past the mouth of the Golfo Dulce.

Monkey Head is an eroded volcanic rock pinnacle rising out of the waters of the Gulf of Papagayo, named for its distinctive silhouette above the surface. Submerged, the formation transitions into sprawling volcanic boulders, shelves, and sandy gullies that funnel ocean currents. Divers frequently encounter pelagic visitors passing through open water along the outer edges while bottom-dwellers rest in the sand channels between rocky outcroppings.

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.

Situated within the sheltered waters of the Gulf of Papagayo, Playpen serves as an accessible training ground and macro haven. The site consists of dispersed volcanic rock mounds and sandy patches where divers frequently encounter juvenile reef species seeking shelter.

Located off the coast of the Papagayo peninsula in Guanacaste, Punta Ballena is characterized by rocky volcanic ridges that merge into sandy channels. The bottom structure creates numerous crevices where nocturnal predators rest during the day. Plankton-rich Pacific currents often draw in large schools of pelagic fish and passing rays, while bottom dwellers populate the boulder slopes.

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.

Sorpresa is an offshore submerged rock formation in the Gulf of Papagayo, named for the unexpected encounters that pelagic currents often sweep past the pinnacle. The formation rises from a sandy seabed with no surface marker or shallow top, demanding precise buoyancy and controlled descent in open water. Massive boulders and fissures break up the rock face, harboring resting nurse sharks, morays, and dense clouds of Pacific reef fish.

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.

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.
