Green Gardens is a coastal site in Canada featuring a volcanic shoreline with sea stacks and underwater caves. Snorkellers access the water from the shore after a 4.5km hike and a steep 86-step staircase. The site consists of reef and kelp forest habitats at depths ranging from 1 to 10 metres, with an average of 5 metres. Visibility varies between 10 and 25 metres. Conditions include moderate currents, surge, and surf. The environment is cold, with temperatures ranging from -1°C to 17°C, often remaining near 4°C. Due to the cold water, entanglement risks, and overhead environments, this site is suited for advanced snorkellers. Drysuits are recommended for comfort.

Gadd's Wall is a marine wall dive site located on the West Coast of Canada. The site features deep fjord topography that brings cold-water conditions close to the surface. Divers can expect visibility ranging from 15 to 30 metres with mild currents. Water temperatures fluctuate significantly throughout the year, ranging from -1C in late winter to 17C in August. Access to the site is via the shore. Due to the nature of the wall and the variable cold-water conditions, this site is best suited for intermediate divers. Snorkelling is also possible at this location.
