Port Hardy sits within Browning Pass, a single sub-area that contains all of the region's sites. The diving ranges from intermediate wall and drift dives to expert-only tidal runs, with Nakwakto Rapids among the fastest-current sites around. Snorkelling is also available at shallower spots. Invertebrate life dominates: Mottled Star, Sea Anemone, Plumose Anemone, King Crab and nudibranchs such as White-lined Dirona are observed across virtually every site. Harbor Seal is frequently encountered, with Humpback Whale, Orca and Steller Sea Lion appearing occasionally.

Water is cold year-round, warming slightly through summer before dropping again into autumn. The warmer months from late spring through early autumn bring conditions most divers find comfortable and coincide with the peak of logged visits. Currents can be extreme at sites like Nakwakto Rapids, so timing dives to tidal windows is essential regardless of season.

Browning Wall is accessible to intermediate divers comfortable with drift diving, while Nakwakto Rapids is strictly for experts due to extremely powerful tidal currents. Beginners would be better served building experience elsewhere before visiting. The snorkelling sites offer a gentler entry point to the area's marine life.
Both of the featured dive sites, Browning Wall and Nakwakto Rapids, require boat access. There are currently no listed dive operators based in the region, so visiting divers should arrange a liveaboard or charter before arriving. Shore-access snorkelling options exist within Browning Pass alongside the boat-access sites.
Browning Pass is the single sub-area containing all of Port Hardy's sites, and it offers a range of underwater terrain. Wall dives, reef dives and drift dives are all represented. Browning Wall offers a vertical reef face with manageable drift for intermediate divers, while Nakwakto Rapids delivers an intense high-current experience for experts only. Shallower reef sites serve snorkellers and less experienced divers.
