Our family had a lot of fun staying and playing in Key Colony Beach. The marina is about five minutes on the water to Vaca Cut. I was amazed how nice it is inside the bay, even when the winds pick up in the afternoon. Having the tiki bar here after the boating is nice. It is a nice place to kayak with all the mangroves.
Marathon is Just the Best for sup paddling and boating. I say Marathon, but I mean the area from Big Pine Key up to past Curry Hammock State Park. It is an area of about fifteen miles and there are plenty of bridges except around mile marker 50. From mile marker fifty you have to go about three miles to make it to the Seven Mile Bridge.
