This place is world famous and I stop here everytime I drive through the Keys. Located at mile marker 79.5, Robbie's Marina is home to a resident school of a hundred or more tarpon and some of them are world record size. This spectacle started out as one injured tarpon that hung around the charter boats in the 70's eating the fish scraps and over the decades hundreds more have joined the party. Most Keys marinas have a school of resident tarpon but none are as impressive or tame as the ones at Robbie's. They charge you $1 to go out on the dock and $2 for a bucket of bait and that's a bargain, especially if you're heading to Key West to go fishing for the silver king.You can really see how these fish feed up close and personal Also, the food at the Hungry Tarpon restaurant at Robbie's is excellent.
