Are you looking for the best scuba diving in all of Mexico?! I recently visited the island of Cozumel off the coast of the Yucatan near Cancun , and had a wonderful opportunity to scuba dive with Scuba Tony ( https://www.scubatony.com/ ) , Cozumel's #1 Scuba tour operator for 4 days in some of the most incredible scuba diving I've ever experienced.
The guys at Scuba Tony were incredibly nice and professional and would highly recommend them, here's a few pictures I captured. Be sure to check them out for a wonderful time.
