Punta Albemarle, located at the northern tip of Isabela Island, offers a challenging combination of reef, wall, and drift diving. The topography features a wall that descends from 25 to 100 metres, requiring careful depth management and advanced certification. Divers encounter moderate currents that can shift quickly, often accompanied by cold upwellings from the Cromwell current. Visibility typically ranges between 10 and 30 metres. Due to the deep nature of the site, strong currents, and the presence of sharks, this location is suited for intermediate to advanced divers. A surface marker buoy is essential for all entries, which are conducted by boat.

Trash Point is a reef dive site located off the Isabela and Fernandina Islands. Divers typically experience an average depth of 11 metres during 45-minute dives. Access to this site requires a boat. Conditions at the site are variable, with visibility ranging from 6 to 30 metres and water temperatures fluctuating between 21C and 26C throughout the year. The site is suited for intermediate divers due to the presence of moderate currents, surge, and the potential for cold water and low visibility. As a marine reef environment, the site offers a typical underwater topography for the region.

Punta Vicente Roca is situated on the northwestern nose of Isabela Island, Ecuador. This site features steep volcanic walls and sea caves that provide a complex topography for snorkellers. Access is exclusively by boat due to the distance from shore. The site is subject to strong currents and variable visibility ranging from 8 to 33 metres. Water temperatures fluctuate between 21C and 26C throughout the year. Given the challenging current conditions, this site is best suited for intermediate-level snorkellers. The nutrient-rich waters are influenced by cold-water upwellings, creating a dynamic marine environment.

Roca Redonda is an isolated volcanic pinnacle located in the northern Galapagos. This site features wall diving that extends from the surface to a depth of 35 metres, with an average depth of 18 metres. Divers must be prepared for strong currents and surge, which are common due to upwellings from the Humboldt Current. Visibility is highly variable, ranging from 5 to 30 metres. Given the challenging conditions, including cold water and boat traffic, this site is strictly for advanced divers. Boat access is required, and the use of a surface marker buoy is essential for safety. Proper buoyancy control and careful monitoring of dive profiles are necessary at all times.

Tagus Cove is a historic deep-water bay located on the west coast of Isabela and Fernandina Islands. This site features a combination of reef and wall topography, with steep cliffs dropping into the water. Snorkellers can explore depths ranging from 8 to 30 metres, with an average depth of 24 metres. Access is strictly by boat due to the distance from shore. Conditions at this site vary, with visibility ranging from 6 to 30 metres and currents that can be strong. Given these environmental factors, the site is best suited for intermediate snorkellers.

Tagus Cove is a sheltered bay located on the western coast of Isabela Island, situated below Darwin Lake. This site offers a varied underwater topography featuring reefs and walls suitable for intermediate divers. Access is exclusively by boat. Divers should be prepared for moderate currents and surge, with depths typically ranging between 20 and 40 metres. Visibility fluctuates between 10 and 25 metres. Water temperatures generally range from 18 to 23C, though significant drops are common due to upwelling from the Cromwell Current and frequent thermoclines. Hazards include cold water, strong currents, and surge. The site is also suitable for snorkelling.

Punta Espinoza, located on Fernandina Island, is a reef site accessible only by boat. The topography supports a variety of marine life, including very common wrasses and sea stars, alongside common cardinalfish and grunts. Divers and snorkellers may also encounter uncommon species such as California sea lions, horn sharks, king angelfish, groupers, blue-barred parrotfish, scorpionfish, pufferfish, Sally Lightfoot crabs, Panamic cushion stars, and sea hares. The site is known for its marine iguana colony, with individuals occasionally observed feeding underwater. Depths range from 6 to 24 metres, averaging 18 metres. Conditions include moderate currents, surge, and visibility between 8 and 30 metres. Cold upwelling from the Cromwell Current can cause significant temperature drops.
