Underworld Tulum - Cozumel
Underworld Tulum in Cozumel leans into the island's famous drift diving. We've found their operation slick, focusing on small groups which really helps when you're trying to spot a shy toadfish in the current, or just want some space on the reef. If you’re looking to get certified, they offer courses, but we’d pick them for their guided fun dives, especially if you want to explore the deeper walls without feeling rushed. They know the good spots to catch a current, making for some effortless flying along the reefs.
