Sechelt Inlet is a deep saltwater fjord on British Columbia's Sunshine Coast, connected to the Strait of Georgia. The water is cold throughout the year, reaching its warmest in summer at around fifteen degrees Celsius and dropping to seven degrees in winter. The defining site is the HMCS Chaudiere, a decommissioned Royal Canadian Navy destroyer scuttled as an artificial reef, accessible by boat and suited to intermediate divers. Shore-entry sites at Tuwanek Beach, Coopers Green, and Sargeant Bay Provincial Park offer rocky walls, kelp forests, and seagrass beds for beginners. Tidal currents in the inlet require careful timing. Species recorded include California sea lion, harbour seal, Pacific electric ray, dogfish, and several nudibranch species.

Water temperature stays cold all year, ranging from around seven degrees in winter to fifteen degrees in summer, making a drysuit or a well-configured thick wetsuit appropriate for most of the year. Tidal currents run through the inlet and require divers to plan entries around the tide, particularly at the Chaudiere wreck and similar exposed sites.
