Vaca Key is a huge nature filled island just off the coast of Marathon, next to boot key harbor. If you are going to do some boating or fishing in the area, then this will one of the place you will likely go. Because the island is not populated, the wildlife and nature vegetation flourishes. We go here to get our bait fish before heading off shore to chase the Yellowtail Snapper and Mahi-Dolphin Fish.
Between Vaca Key and Boot Key is the coolest boating waterway named Sister Creek. This area is really excellent to cruise around in a small or medium sized boat, so you can get into the skinny little side canals and tidal flows.
The boat ramp over at Vaca Cut is the top spot to launch your boat on the upper end of the island. In the middle, go to the 33rd Street Boat Ramp to drop in. Both of the main Boat Ramps are on the bayside, so you have to buzz around to get oceanside.
