First few minutes of footage are from El Cedral (where we saw several nurse Sharks and reef sharks) and Palancar Bricks.
Night dive was called "Francisco" I believe. Many octopus, lobsters.
Middles dives at Columbia Reef, Columbia Bricks, Tormentos, Yucab Reef. Turtles, occasional nurse shark, some macro stuff I couldn't capture with a GoPro.
Punta Sur and Columbia caves had the most dramatic reef structures, "skyscrapers" and swim throughs.
I am a mere novice as far as Cozumel goes, most of the people I dived with had 200+ dives in Cozumel alone.
Thanks for the information. Got my feet wet diving Columbia and Palancar. They were really nice dives
