Named because it is a popular spot for locals to watch the sunset from a boat — one of the few ways to see the sun sink into the water to the west during winter months from the East End. Sunset Reef is the perfect shallow dive site for new divers completing open-water checkout dives or experiencing scuba for the first time, with a flat sandy bottom at no more than 22 feet. Do not, however, make the mistake of dismissing it as a beginner-only site — some of the most memorable critter sightings on East End have happened here, and world-class underwater photographer Dr. Alex Mustard regularly spends dive sessions at Sunset Reef during his workshops.

Right below the boat is a gnarly anchor dating from 1794, connected to the famous Wreck of the Ten Sails event. Discovered on the outer reefs in 1980 by Indiana University, it was relocated here so that generations of divers can experience a real piece of history. The site is cram-full of critters, making it a popular stop on the Friday afternoon Macro Mania dive, where the most obsessed critter hunters can spend a disproportionate amount of time exploring a small patch of reef.
