    Site Overview

    Dente de Cao is a advanced pinnacle dive site located off the Boa Vista coastline in Cape Verde, offering an extraordinary combination of volcanic underwater landscapes and rich Atlantic marine biodiversity. The site is accessed by boat from Sal Rei, typically 24 to 20 minutes depending on sea conditions. Dente de Cao reaches a maximum depth of 30 meters with the most productive diving occurring between five and 25 meters where the volcanic walls and reef structures provide shelter and feeding grounds for diverse marine species. The underwater topography features dramatic volcanic formations including vertical walls, overhangs, coral-encrusted pinnacles, and sandy channels that create a mosaic of distinct ecological zones. Marine life encounters commonly include Barracuda, Yellowfin Tuna, Parrotfish, Common Octopus, along with numerous smaller reef species that inhabit the volcanic substrate. The water temperature ranges from 21 degrees in winter to 27 degrees in late summer, with visibility typically between 15 and 30 meters during the calmer months from May through November. Seasonal visitors including humpback whales from February to May and whale sharks from July to October add an extraordinary dimension to dives in this region. The site's position in the eastern Atlantic means it benefits from nutrient-rich upwellings that sustain prolific coral growth and attract large pelagic species year-round. Boa Vista is increasingly recognized as one of Cape Verde's premier diving destinations, offering uncrowded conditions and authentic Atlantic diving experiences that remain largely undiscovered by the broader diving community. The challenging conditions including strong currents, significant depth, and exposure to open Atlantic conditions demand experienced divers with appropriate certifications.

    Dive Briefing

    "The descent begins from the dive boat moored above the reef structure after your guide assesses current direction and strength. The dive profile typically begins with a gradual descent along the reef wall to approximately 17 meters where the current-facing side offers the best marine life encounters. Barracuda are frequently observed patrolling the wall at 14 to 22 meters, while Yellowfin Tuna inhabit the coral gardens and overhangs throughout the mid-section of the dive. The volcanic substrate between 12 and 25 meters is encrusted with colorful sponges, gorgonian fans, and endemic Cape Verde corals that provide excellent macro photography opportunities between the larger species encounters. Parrotfish can be found in crevices and ledges throughout the site. Your guide leads you progressively shallower along the reef contour, ensuring adequate bottom time for the safety stop at five meters. The final portion of the dive is spent exploring the shallow reef flat at three to eight meters where coral diversity is highest and sunlight creates ideal conditions for wide-angle photography. The safety stop is conducted along the upper reef before surfacing and returning to the boat for a total dive time of approximately 50 to 60 minutes."

    Traveler Notes

    Who is this for?

    Dente de Cao is intended for experienced Advanced Open Water certified divers with at least fifty logged dives and proven competence in strong currents, deep profiles, and challenging Atlantic conditions. The site demands excellent buoyancy control, disciplined air management, and the ability to maintain group cohesion in potentially demanding conditions at depths reaching 30 meters. Divers must be comfortable with drift diving techniques, negative entries, and SMB deployment in open water. The site rewards advanced practitioners with spectacular pelagic encounters including sharks, large schools of trevally and barracuda, and seasonal visits from whale sharks and manta rays. Technical photographers will appreciate the dramatic volcanic topography and the opportunity to capture wide-angle images of large marine life against the deep blue Atlantic backdrop.
