Four hundred kilometres off Baja California, Isla Guadalupe sits in cold Pacific upwelling that draws adult great white sharks with near-certain regularity each autumn on multi-day liveaboard cage expeditions. Crystal visibility often exceeds thirty metres, and individual sharks return year after year, giving divers named-animal encounters rare anywhere else on Earth. September and October mark the apex of the season when the largest females dominate the submersible cages.

Up to 98% sighting chance in Isla Guadalupe (Mexico). Best months: September, October, August.
The liveaboard season typically runs August through November, with September and October offering the highest shark activity and the largest females around the submersible cages.
Five-day liveaboard cage diving packages generally run 55,000 to 82,000 MXN per person (2026 prices), roughly 3,000 to 4,500 USD excluding flights to Ensenada and biosphere park fees.
All diving is from liveaboard cages: surface cages for snorkelers and hookah divers, plus submersible cages lowered to roughly 9 to 12 metres. No open-water diving without a cage is permitted.
Boats depart Ensenada, Baja California for the 400 kilometre passage to Isla Guadalupe Biosphere Reserve. Mexican regulations cap visitor numbers, ban chumming near cages, and require licensed operators only.
No advanced certification is needed for surface cages. Submersible cage dives may use hookah air or scuba depending on operator, but open water certification is sufficient for most programs.
