Harney Toe is an artificial reef located in Puget Sound, United States. This shallow site sits at an average depth of 4 metres, with a range of 3 to 5 metres. Access is by boat only. Divers should prepare for cold water temperatures between 8 and 14 degrees Celsius and variable visibility ranging from 5 to 10 metres. Due to the artificial structure, divers must remain aware of entanglement risks and maintain careful buoyancy control. The site is suitable for intermediate divers who should use a torch to inspect the reef structure. A thick exposure suit is recommended to manage the cold conditions.

Lime Kiln Point in Puget Sound features a diverse underwater topography consisting of reefs, kelp forests, and steep walls that drop off into deeper water. The site is suitable for advanced divers due to strong currents, cold water temperatures ranging from 6C to 10C, and potential surf conditions. Depths vary significantly, ranging from 8m to 60m with an average of 9m. Visibility fluctuates between 3m and 18m. Shore access is available, supported by facilities including parking, toilets, showers, a rinse station, and a cafe. Guided tours and a dive shop are located on-site to assist with logistics.

Cooper Reef, located off the coast of Victoria, Canada, offers a temperate marine environment defined by its reef structure and kelp forest. Divers access this site by boat, with depths ranging from 10 to 30 metres. The site is suited for intermediate divers due to the presence of mild currents and occasional surge. Visibility typically spans 10 to 20 metres. Water temperatures remain cool throughout the year, fluctuating between 8C and 11C. A standard dive at this location lasts approximately 45 minutes.

South Cod Reef is a rocky reef structure located in Victoria, Canada, offering depths ranging from 10 to 110 metres. While the shallower sections are accessible to open water certified divers, the deeper areas are reserved for advanced divers. Divers can expect mild currents and visibility between 10 and 15 metres. Water temperatures remain consistently cool, between 8 and 10 degrees Celsius, necessitating the use of a drysuit. Hazards include entanglement risks and sharp coral or rocks on the seabed. Divers should maintain neutral buoyancy to avoid contact with the substrate, where sea urchins are present. Boat access is required to reach this site, and no amenities are available.

Skyline Wall is a marine site in Puget Sound featuring a wall and reef structure that drops from 2 to 27 metres. The topography includes a kelp forest and seagrass beds in shallower sections. Divers encounter Northern Elephant Seals, Harbor Seals, Giant Pacific Octopuses, Wolf-eels, and Kelp Pipefish, alongside various crabs, shrimp, and nudibranchs. Conditions include strong currents and visibility ranging from 5 to 10 metres. Water temperatures remain between 8 and 9 degrees Celsius, requiring thermal protection. Shore entry requires navigating a surf break. Divers should manage entanglement risks within the kelp and time entries around slack water to mitigate the strong currents.

North Cod Reef is a marine site located off the coast of Victoria, Canada. The reef topography spans depths between 5 and 35 metres, with an average depth of 20 metres. Divers should expect cold water temperatures ranging from 8 to 11 degrees Celsius, making drysuits necessary. Visibility typically fluctuates between 5 and 15 metres. Access is by boat only, and the site is suited for intermediate divers due to mild currents and potential hazards including boat traffic and cold water. Species recorded around this area include harbour seals, various nudibranchs, and jellyfish. Divers should deploy a surface marker buoy on ascent and plan surface intervals carefully.

Johnstone Reef is a marine reef site located off Vancouver Island, British Columbia. Divers can explore this area at depths ranging from 7 to 12 metres. The site is accessible via both shore and boat entries, though divers should be prepared for moderate currents and visibility between 5 and 10 metres. Water temperatures remain cold, consistently between 8 and 10 degrees Celsius, making dry suits essential for comfort. Hazards include boat traffic and cold water conditions. Divers should deploy a surface marker buoy before ascending to ensure visibility to passing vessels. The site is suitable for beginners, with typical dives lasting approximately 45 minutes.

Fulford Reef, located off the coast of Victoria, Canada, features a combination of kelp forest and reef topography. The site ranges from 5 to 30 metres in depth, with an average depth of 18 metres. Divers should be prepared for cold water temperatures between 8 and 9 degrees Celsius, necessitating appropriate thermal protection. Visibility typically spans 10 to 20 metres. Access is strictly by boat, and divers must manage surge and swell conditions, which can impact the shallower kelp sections and ascent. The site is suited for intermediate divers, with typical dive times around 45 minutes.
