Reef Dives

1. Plan a tryst with turtles at Agana Bay Dive Site

Agana Bay is a coveted dive site in Guam. It is especially renowned for ‘drift diving,’ a type of scuba diving where tidal currents propel the diver further, allowing them to span longer distances underwater with ease. This diving spot is located across from the AMT Beach House dive shop, and it is lined with both hard and soft corals.

Divers will be delighted to encounter stunning turtles and reef fish, along with a multitude of other marine gems at this site. Although it is known as a boat dive site, one can also engage in shore diving at this bay.

Access to this site can be found near Sheridan Hotel. This site features shallow reef flats, making it accessible and suitable for divers of all calibers. Ornamented with hard and soft corals, it is not only home to turtles, but also to a variety of reef and pelagic fish.

3. Swim with the sharks at 11-Mile Reef

Known as one of the most exhilarating diving experiences on the island, the 11 Mile Reef site is also one of the most arduous dives because of its strong reef currents and erratic swells.

This boat dive is not for the faint-hearted, and access to the site can prove to be rough due to choppy seas. Don’t forget to keep your eyes peeled for pilot whales or spinner dolphins. Once you take the plunge, you will be greeted by a diverse range of marine fauna, such as sharks, turtles, and barracuda and pelagic fish.

On a fateful day in 1943, the Japanese passenger-cargo ship Tokai Maru sunk to Apra Harbor’s depths in Guam. Since then, it has clung to its watery grave beside another war wreck, the SMS Cormoran II, which sunk during World War I. Over the years, this has collectively become one of the most intriguing shipwreck dive sites on the island.

Located about 120 feet (26.5 meters) deep, the Tokai Maru dive site is one of the most enduring vestiges of world war history under the surface of the sea. Its intrigue is further heightened due to the fact that both the Tokai Maru and SMS Cormoran II, wrecks from World War II and World War I respectively, can be sighted here side-by-side.

Owing to its perilous depths that reach up to 140 feet (42.6 meters), the site is only recommended for experienced wreck divers.
