South of Cancun and Puerto Morelos, the snorkeling at Inna is known for a spur and groove reef formation. The access to this dive site is from the shore or by boat. It is a shallow, protected dive site with waters from shallow down to 35 feet deep. Close to shore, the visibility can be variable as the fresh water from the nearby cenote mixes with the saltwater.
After a long day of snorkeling, try heading to the Mamitas Beach Club or the Canibal Royal Club in North Playa del Carmen.
To reach the snorkeling in Inna 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 Inna. 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 Inna.
Overall, Inna is the 27th most popular snorkel dive spot of all 40 snorkeling dives in Mexico.
