Wall Beach

Wall Beach is a shore dive located at the end of Seahaven Road, just off Wall Beach Road, in Nanoose Bay near Nanaimo, British Columbia. The site's defining feature is a long, low sandstone shelf — more of a gradual shelf than a dramatic drop-off — that extends in both directions once reached, flanked by sculpted sandstone ledges, cracks, and pockets in the shallows, mid-depth rock formations, and a rocky rubble field with scattered boulders to the right. Depths range from about 3 m (10 ft) in the shallows to beyond 24 m (80 ft), though most of the site's interest lies above 18 m (60 ft), and the bottom transitions from sandstone flats and shelves to boulders and rubble at depth.

Entry is from shore across a sloping flat sandstone shoreline, which becomes very slippery at low tide; planning the dive around higher water levels makes for safer footing. From the entry point, divers swim straight out for roughly 8 to 10 minutes to reach the main sandstone shelf. Navigation is straightforward, and the simple bottom contours suit both casual exploration and wildlife-focused dives.

The site holds a solid variety of marine life. Giant Pacific octopus and wolf eels are found tucked into the boulder piles and right-hand rubble field, while large schools of perch frequent the shallows. Rockfish, kelp greenling, lingcod, and sculpins are present throughout, along with nudibranchs and other invertebrates. A nearby sea lion colony brings sea lions into the site, particularly from November through March, when they make swift, close passes before moving on — exciting but potentially startling for newer divers.
