Punta Sur, in the Sea of Cortez, offers a solid dive for those looking to explore the region's usual suspects. We've often spotted playful sea lions here, along with schools of jacks zipping past the rocky reefs. It's a straightforward dive, good for knocking out a tank in between longer journeys and suits divers comfortable with typical Cortez conditions. Expect decent visibility, though currents can pick up sometimes.
