Our cruise ship the Norwegian Jewel stopped here in February, 2015. We arranged ahead of time for a snorkeling trip with Loes and Cozumel H2O. The big difference with this company is personal attention! I have been on snorkel trips where 50 people jumped into the water at the same time and people were crawling over each other to see the best sights. There were only 4 of us with H2O Cozumel and Loes gave us individual attention with any equipment issues and then we followed her as our guide to see the best marine and coral life. We went to four different snorkel locations and saw starfish, a small nurse shark, a huge spotted eagle ray, turtle, barracuda, and a wide variety of fish. Loes even went through a picture guide of the types of fish we would possibly see as we traveled to our fist snorkel sight. Plenty of water, snacks, and wonderful fruit were also provided on board. The length of our trip was about 4 hours which is much longer than most snorkel trips I have been on. I highly recommend Loes and H2O for a memorable snorkeling trip in Cozumel! Everything was first class!
