11 Mile Reef
This reef is about 300 by 100 yards and can be one of the most exciting dives on Guam. More than 11 miles east of Agat, the 80 – 90 foot upper reef gradually slopes to the sea floor at about 900 feet.
There is a good probability of seeing sharks, barracuda, rays and large schooling fish on this dive. Medium to strong upper reef currents and swells can make this a challenging dive, however, and divers should be experienced and thoroughly briefed.
Pilot whales and spinner dolphins are frequently seen on the way to this site. It can be a rocky boat ride even on the best of days, however, so divers that have a tendency to get sea sick, be prepared!
