Santa Maria Bay is a sheltered Cabo cove with a shallow coral-and-sand bottom, bright tropical fish, and regular ray, turtle, and shark sightings. It works best as a relaxed boat dive or snorkel stop when conditions are calm, with the reef and rocky edges giving it more structure than an open beach. The granite headlands cut down swell and wind, so mornings are usually the calmest and clearest window. It is a strong beginner-friendly option for easy underwater scenery and straightforward photo runs.
