Key Largo question....

If you can get into John Pennekamp that would be the best bang for the buck.
If not try Key Largo Campground.

As far as snorkeling goes, there is no good snorkeling along the shore line of any of the Keys, and that includes what has been posted above. All you will see are hand full of small fish.
You need to take a dive boat out to the reef for the good snorkeling.
Don't take the ones in the state parks. They are like cattle cars.
Take a private one like Quiescence. They only take six people per boat, and will move from one reef to another to make sure you have the best experience and give you individual attention.

We have been wintering in the Keys for the past fifteen years, so I speak from experience.
With that said, Bahia Honda has the best beaches.

At Bahia Honda, we have snorkled off of Loggerhead Beach. All kinds of cool things in the sea grass. Star Fish, and baby tropical fish.

If you can't get into Pennekamp try Point of View

Nicest private place on the key, and brand new!

John Pennecamp in nice but you need to make your reservations now. They book up fast for high season, Nov-May. Also, there are a few private CGs that you can find on woodalls.com

There wasn't anything to see along the shore. We took the boat through the sate park, I think it was about $30 each and approx 10 mile boat ride to the Looe Key National Marine Sanctuary. For us, it was amazing.

Interesting, Bahia Honda is a place i always thought was poor snorkelling but i would love to try it there. Can you access from shore or from boat only?

We stayed at John Pennenkamp Coral Reef State Park - http://pennekamppark.com/. in Key Largo We walked to the snorkeling area. Further down the Keys, we stayed at Bahia Honda State Park and thoroughly enjoyed the snorkeling there. Both state parks offered snorkeling and the snorkeling at Bahia Honda was less crowded with an incredible reef. Either way you will enjoy your time in the Keys.
