Enjoy quick ocean access and easy Gulf access via Vaca Cut, making this an exceptional setup for anglers and boating enthusiasts alike. The waterside outdoor spaces are designed for entertaining and enjoying the Keys lifestyle, featuring string lighting, solar-lit dock pilings, under-dock fish lights that attract snapper and tarpon, and frequent manatee visits along the canal.
