Horseshoe Bay's diving is concentrated within Whytecliff Park, where shore-entry sites span shallow reefs and kelp forests through to deeper walls. The majority of sites suit beginners, with a handful stepping up to intermediate level. Freshwater options at Alouette Lake and Buntzen Lake add variety, the latter serving as a training ground when coastal conditions are unfavourable. Harbor Seal, Dungeness Crab, and a rich nudibranch community define the marine life here.

Monthly water temperature across Horseshoe Bay's sites, from satellite sea-surface data corrected for depth. The band shows the site-to-site spread.
Water temperatures are cold through winter and early spring, warming gradually to their peak in midsummer before cooling again through autumn. The transition months of April and October are flagged as particularly rewarding, likely balancing cleaner visibility with acceptable thermal conditions. A drysuit or thick wetsuit is advisable year-round given the cool baseline.
