Imrie Island, located off the coast of Victoria, Canada, features a shallow reef and kelp forest environment. Divers can explore depths ranging from 3 to 10 metres, with visibility typically between 5 and 10 metres. The site is accessible only by boat, and due to water temperatures consistently between 8 and 12 degrees Celsius, a drysuit is strongly recommended. The area is suitable for beginners building cold-water experience, though divers must remain aware of potential entanglement risks within the kelp. Proper buoyancy control is essential to navigate the reef structure safely while avoiding surf and entanglement hazards near the surface.

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.

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.

Sheep Island is a demanding reef and wall dive located 1000 metres off the coast of Victoria, Canada. The site features depths ranging from 9 to 40 metres, with an average depth of 20 metres. Divers must contend with strong currents that can shift unexpectedly, making this an advanced site requiring drift diving experience. Visibility is variable, typically between 4 and 15 metres. Water temperatures remain cold year-round, fluctuating between 8 and 11 degrees Celsius, necessitating the use of a drysuit and hood. Access is strictly by boat, and divers should plan entries around slack water to manage the challenging current conditions.

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.

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.

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.

Forest Island features a reef structure extending from 3 to 30 metres, providing a range of depths suitable for beginners building experience in cold Pacific waters. Visibility typically ranges between 5 and 10 metres. While currents are generally mild, divers must remain prepared for stronger surges and monitor local boat traffic before entry. Water temperatures remain between 8 and 11 degrees Celsius throughout the year, making a drysuit essential for comfort. Species recorded around this area include harbour seals, East Pacific red octopus, various nudibranchs such as Monterey dorid and Hermissenda, as well as lingcod and toadfish. Boat access is required for this site.
