Snorkeling Grecian Rocks is decent but there are better spots around Key Largo. So why mention snorkeling Grecian Rocks at all? Well, when the wind and waves are blowing in from the Atlantic 10-15 knots or more, Grecian Rocks is where almost all the boat companies will take you. It is a bit protected from the wind and waves compared to other reefs nearby. But hey, if it’s windy, you might as well get in the water. You will see some neat stuff.
To snorkel Grecian Rocks we took a boat tour out of Key Largo, but you can also get on one in John Pennekamp Park. It was blowing 15-20 knots, and was a fun and bumpy ride out to the spot. The captain had to be very careful as he approached the reef and it took a few tries to get anchored.
Snorkeling Grecian Rocks was decent given the wavy and windy conditions. There was a fairly strong current we had to swim into to get to the reef from the boat. And the water was pretty cloudy, but not too bad considering the waves and wind. Our pictures did not turn out very good because of the conditions.

What We Saw While Snorkeling Grecian Rocks
The reef was in OK shape, but not great. Much of the hard coral was dead. Although there were a few interesting ones. There was a decent amount of soft corals and sponges. The purple fans looked less healthy than we have seen, and the coral had a lot of algae attached to it. We also noticed a handful of small Branching Fire Coral.
While snorkeling Grecian Rocks we saw a decent amount of fish, but not a lot. We did see a bunch of huge parrotfish. We saw a handful of Hogfish, which are fun to watch change colors (see below).
Snorkeling Sunburns Suck!
Check out the snorkeling rash guards, wetsuits, and reef safe sunscreen we use to protect ourselves and to protect fish and coral from sunscreen chemicals.
We were not able to snorkel over the top of the reef much because it was very shallow and there was surge and waves, so it was not the best time to really see it. We noticed some bigger fish species out over the reef, like a huge grouper. We saw a nice Smooth Trunkfish, barracuda, Blue Tang, goatfish, Porkfish, chub, and some big jacks. We noticed a green parrotfish with another fish cleaning it. We also saw lots of Bluestriped and French Grunts. We noticed the Cleaning Goby and a handful of Bluehead Wrasses.
You can see a conch shell in the picture at right. Even though the keys are called the Conch Republic, there are very few live conch in the waters.
