Status today: Clean · Beach Score 78/100
A palm-lined local favorite in the middle Keys, free to enter and genuinely pretty. Atlantic-facing, it catches seasonal seaweed, and the county rakes on a schedule rather than daily — so timing matters in summer. Off-season, it is one of the nicest free beaches in the Keys.
