Campbell River's diving centres on tidal reef systems, walls, kelp forests, and the decommissioned naval vessel HMCS Columbia, which functions as an artificial reef. Quadra Island, within the Discovery Passage, offers the widest variety of site types, including drift diving driven by strong tidal flow. Marine life is notably rich in echinoderms, nudibranchs, and large invertebrates: Giant Pacific Octopus, Wolf-eel, Dungeness Crab, and Puget Sound King Crab are all observed regularly. Most diving is boat-access and suited to intermediate divers, though some beginner-friendly reef sites exist.
