Key Dive Site Facts
Dive Site Overview
Sharks Cave, known locally as Cueva del Tiburon, gained its name from the consistent presence of sharks within and around its structure. Positioned close to the shore of Isla del Caño, the site features a distinct sandy reef leading to a small hole in the rocks, which opens up to the main cave system.
While divers approach closely to observe, direct entry into the cave is generally not practiced. The dive depth typically ranges between 10 to 15 meters (30 to 50 feet), allowing for extended bottom times. Proximity to shore means visibility here can fluctuate, sometimes being less than open-ocean sites.
The surrounding rocky outcrops also create habitats for a variety of smaller creatures, enriching the overall exploration of this compact yet active dive area. Observing sand eels making homes within encrusting corals offers a different perspective on the localized ecosystem.
Best Time to Dive
Planning a dive at Sharks Cave is best during Costa Rica's dry season, which runs from December to May. During these months, divers generally encounter calmer seas, enhancing the overall experience. Air temperatures during this period average around 27-28°C (81-82°F), with minimal rainfall, typically less than 5 mm. While the rainy season from June to November can bring increased pelagic sightings elsewhere, Sharks Cave's nearshore location and primary draw of resting sharks make the dry season preferable for consistent conditions. Wave heights remain relatively low from December through April, averaging around 1.1 to 1.3 meters. Dive conditions during these months generally receive a 'Good' score in system data, indicating favorable environmental factors.

Dive Experience & Conditions
Exploring Sharks Cave centers around its distinct geological features: a sandy reef transitioning to rocky formations and the cave itself. Divers navigate down to depths between 10 and 15 meters (30 and 50 feet) on average. Visibility at this nearshore site can vary, ranging from around 10 meters (30 feet) up to 25-30 meters (80-98 feet) depending on recent weather and currents. Water temperatures are consistently warm, generally between 26° to 29°C (79° to 84°F), though localized thermoclines can sometimes be present in deeper sections. While strong currents are not consistently reported for this specific site, local conditions always warrant attention. The dive path typically involves observing the cave's opening and exploring the surrounding sandy and rocky terrain, maximizing interactions with the resident marine life.
Dive Difficulty & Safety Guidelines
Approaching Sharks Cave requires careful attention to buoyancy control and situational awareness. Given the presence of a cave, divers must respect the boundary of not entering the interior, as per standard practice at this site. Maintain a comfortable distance from the cave opening, allowing space for marine life and fellow divers. Varying visibility, particularly due to the site's proximity to shore, demands divers stay in close proximity to their buddies and adhere to dive leader instructions. Always monitor air consumption and bottom time, especially when focusing on observing marine life. A thorough pre-dive briefing will cover current conditions and specific protocols for engaging with the site safely.

Marine Life at Sharks Cave
The most immediate draw to Sharks Cave is, predictably, the sharks. Divers often spot white-tip reef sharks resting calmly on the sandy bottom just outside the cave's entrance. Observing these creatures in their natural repose provides a compelling highlight. Beyond the sharks, the rocky outcrops and sandy reef teem with activity. Look for grunts and big eye fish schooling near the cave. Closer inspection reveals creatures like lobsters and moray eels tucked into rock crevices, alongside vibrant butterflyfish fluttering through the shallower sections. Occasionally, divers might encounter manta rays and other pelagic stripes passing through the area, adding a dynamic element to the dive.
