Historic shipwrecks. Colorful coral reefs. Amazing marine wildlife. NOAA's national marine sanctuaries and estuarine research reserves offer all this and more to diving enthusiasts in coastal U.S. states and territories.
NOAA sanctuaries and reserves are protected areas that help us conserve these special coastal and marine places for future generations, while still enjoying all they have to offer today. Diving is just one of many recreational opportunities available at our these sites.
A few tips to help you safely enjoy your diving adventure:
- Don't collect underwater souvenirs. Leave these behind for others to enjoy.
- Enjoy viewing marine mammals and wildlife from a safe distance.
- If you see corals, please don't touch. Keep your fins, gear, and hands away from coral reefs, as this contact can hurt you and will damage delicate coral animals.
