Arachne Reef is a shore-entry site located in Victoria, Canada, offering a reef environment with depths ranging from 5 to 21 metres and an average depth of 10 metres. Divers experience visibility between 10 and 20 metres, with water temperatures fluctuating between 8 and 11 degrees Celsius throughout the year. The site is subject to moderate currents and surface surge, requiring careful timing around slack water for entry and exit. Due to the cool water temperatures, a drysuit or thick wetsuit is necessary for this 60-minute dive. The reef structure supports various invertebrates, including ochre sea stars, leather stars, orange sea cucumbers, and crabs, with occasional sightings of harbour seals.

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.

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.

Rubly Island is a challenging shore-entry reef site located in Victoria, Canada. The topography features a significant drop-off, descending from 8 metres to depths of 120 metres. Due to the strong currents and unpredictable surf at the entry point, this site is strictly for advanced divers. Visibility is typically limited to 4 to 6 metres, requiring precise navigation and buoyancy control. Water temperatures remain between 8 and 10 degrees Celsius throughout the year, necessitating the use of a drysuit. Divers must consult current tables to time their entry with slack water and remain vigilant regarding surface boat traffic and the overhead cave environment.

Graham's Wall is a challenging wall and reef site located in Victoria, Canada. The topography drops from 9 to 40 metres, with an average depth of 25 metres. Divers must contend with strong currents, making it essential to plan dives around slack tide. Visibility typically ranges from 15 to 30 metres. Water temperatures remain cold year-round, between 8 and 11 degrees Celsius, requiring appropriate thermal protection. Access is via a shore entry with on-site parking available. Due to the depth, current, and cold water conditions, this site is suited for intermediate divers with solid buoyancy control. A surface marker buoy is recommended for all dives.

Domville Island is a drift dive site located off the coast of Victoria, Canada. The reef topography ranges from 10 to 27 metres in depth, with an average depth of 20 metres. Due to strong currents, this site is suitable only for advanced divers. Visibility varies between 5 and 20 metres, and water temperatures remain cold, between 8 and 11 degrees Celsius. Access is by boat only, and divers must manage hazards including boat traffic, entanglement risks, and cold water. Species recorded around this area include harbour seals, California sea lions, various nudibranchs, and jellyfish. Divers should time their entry to slack water using local current tables.

Joan Rock is a boat-access reef and pinnacle site located off the coast of Victoria, Canada. The site features a kelp forest and reaches depths between 3 and 16 metres. Conditions are generally calm and current-free, making it suitable for beginner divers. Visibility typically ranges from 5 to 10 metres. Water temperatures are cold, fluctuating between 8 and 12 degrees Celsius throughout the year, necessitating appropriate thermal protection such as a drysuit or a thick wetsuit. Divers should exercise caution regarding the risk of entanglement on any wreckage structures present at the site and maintain proper buoyancy control to avoid protrusions.

Reay Island is a boat-accessible reef and wall dive located off the coast of Victoria, Canada. The site features a vertical profile descending from 8 metres to a maximum depth of 30 metres, with an average depth of 15 metres. Divers should expect strong currents, making precise timing around the slack tide essential for a successful 50-minute dive. Visibility is typically limited to 6 to 9 metres, and water temperatures remain cold, ranging from 8 to 11 degrees Celsius throughout the year. Due to the challenging current conditions and the presence of kelp forests, this site is best suited for intermediate divers with strong buoyancy control and cold-water experience.
