Gray's Reef
National Marine Sanctuary

Gray's Reef National Marine Sanctuary is an ocean park teeming with life. The natural live-bottom habitats of the sanctuary are representative of others across the region. The sanctuary provides year-round opportunities for sport fishing, recreational diving, and boating. The research area within the sanctuary hosts one of the only designated no-take zones in the region, which makes Gray's Reef a catalyst for scientific research studying water quality, ocean noise, hurricane prediction, and climate change.
