Punta Maria is a high-energy wall and reef site located 500 metres off Cocos Island. This advanced dive features depths ranging from 20 to 36 metres, with an average depth of 25 metres. Divers encounter strong currents, surge, and variable visibility between 15 and 30 metres. Thermoclines frequently cause temperature drops within the 25 to 28C range. Due to the exposed nature of the site and unpredictable current shifts, boat entry is required. Divers must possess advanced certification and strong buoyancy control skills to navigate this remote environment. Always confirm conditions with your liveaboard crew and maintain a surface marker buoy for safety during drift dives.

Isla Cascara is a reef site located within the Cocos Island marine reserve, accessible only by boat. The site features a reef and cave system with an average depth of 25 metres. Water temperatures are warm, typically ranging between 27 and 30 degrees Celsius, though thermoclines can cause temporary drops. Visibility fluctuates between 10 and 30 metres, and divers should be prepared for variable conditions. While currents are generally mild, the site is subject to surge and swell.

Big Dos Amigos is a deep pinnacle and reef site located off Cocos Island, Costa Rica. Designed for advanced divers, the site features depths between 20 and 40 metres with an average of 25 metres. Strong currents and surge are defining characteristics, requiring confident drift technique and buoyancy control. Visibility varies from 10 to 30 metres. Access is strictly by boat, and the site is not suitable for snorkelling. Divers must be prepared for deep water conditions and potential cold thermoclines. Always carry a surface marker buoy, as currents can displace divers from the boat during ascent.

Small Dos Amigos is an exposed drift dive located off Cocos Island, Costa Rica, characterised by strong currents and open ocean conditions. The site features a reef topography ranging from 23 to 50 metres, with an average depth of 25 metres. Due to the significant surge, swell, and current, this site is strictly for advanced divers who possess solid buoyancy control. Visibility fluctuates between 10 and 30 metres. Access is exclusively by boat, and divers must remain alert for heavy boat traffic in the area. A surface marker buoy is essential for all dives at this location to ensure safety in the open water.

Manuelita Garden is a reef site located off Cocos Island, Costa Rica, offering diving at depths between 15 and 25 metres. With an average depth of 18 metres and mild currents, the site is suitable for intermediate divers. Visibility typically ranges from 20 to 35 metres, though it can occasionally drop to 5 metres. Access is by boat only, and the site is well-suited for night dives. Water temperatures remain between 27 and 29 degrees Celsius. Divers should be aware of the presence of sharks and maintain close proximity to their guide during dives.

Chatan Bay is a pinnacle and reef site located off Cocos Island, Costa Rica. The site features a consistent depth of 13 metres and is accessible only by boat. Divers should be prepared for moderate currents and surge, which can influence the experience. Visibility at the site typically ranges between 15 and 30 metres. Given the environmental conditions and the nature of the location, this site is suited for intermediate divers. Typical dive times are approximately 40 minutes. Hazards to be aware of include sharks, strong currents, and surge.

Submerged Rock is a deep offshore pinnacle located 1600 metres from the shore of Cocos Island. The site topography features a mix of open-water pinnacle diving and cave sections, with depths ranging from 20 to 42 metres. Divers must be prepared for moderate currents, surge, and overhead environments. Visibility typically fluctuates between 10 and 30 metres. Due to the depth and conditions, this site is strictly for advanced divers with deep certification. Boat entry is required, and divers should remain aware of potential entanglement risks within the structure. Water temperatures generally range from 24 to 27C, though occasional thermoclines can cause temperatures to drop into the low 20s.
