To reach the snorkeling in Aquario by air, you will need to fly into Cancun International Airport (Aeropuerto de Cancun - CUN). Some of the hotels provide shuttle vans or there are shuttle vans to be hired down to Aquario. Renting a car to drive around can be hazardous do to the potential for unwarranted police stops resulting in required immediate cash payments. An alternative airport option is to fly into Aeropuerto Internacional de Cozumel (CZM) and take the ferry from Cozumel to Playa del Carmen. From there, you can take a much shorter shuttle van down to Aquario.
Overall, Aquario is the 29th most popular snorkel dive spot of all 39 snorkeling dives in Mexico.
