Explore Guam

Diving in Guam presents a unique blend of natural beauty and historical intrigue, making it an exceptional destination for underwater enthusiasts. As one of the most affordable diving locales in Micronesia, Guam offers pristine reefs and an abundance of marine life due to its limited exposure to mass tourism. Divers of all skill levels can explore Guam's underwater world, with sites ranging from vibrant coral gardens to fascinating historical shipwrecks.

A highlight for many is the opportunity to explore the famous shipwrecks of the German Cormoran and the Japanese Tokai Maru, both sunk during the world wars and now resting side by side at about 30 meters. Beginners can start their adventure with the American Tanker in Apra Harbor, teeming with marine life at a shallow depth of 15 meters. For those seeking thrilling experiences, the Blue Hole offers a dramatic descent starting at 18 meters, where divers can marvel at its depths that extend beyond recreational limits.

Guam's dive sites are primarily concentrated in the south, with Apra Harbor and its outer reefs being key highlights. These areas boast a mix of shipwrecks, hard coral reefs, and dynamic wall sites that can be explored via boat or shore dives. The diverse underwater terrain, coupled with strong currents in certain areas, provides exhilarating drift dives. With its myriad of dive courses available, Guam caters to both novice and advanced divers, ensuring unforgettable experiences in this Pacific paradise.

★★★★☆ Blue Hole - Guam

Blue Hole is a very unusual dive on a natural limestone plateau. A vertical shaft begins at 60’ with a large “window“ opening at 125’. Drift dives are possible. You must be an experienced Deep diver to “shoot the hole“. Great vis and the 30 to 60’ plateau make this a popular site for all divers.

★★★★☆ Barracuda Rock - Guam

This dive site is very popular for our local and visiting divers. Located along the Orote peninsula, an occasional barracuda is seen here, but not as frequent as in the past. Depths range from the very shallow to an average depth of 45’ to over 100’, with an average of about 45’.

★★★★☆ Harley Reef

Harley reef Is a nice and easy dive site for all divers to enjoy! The Harley itself sits in roughly 15 feet of water along the breakwater wall in Apra Harbor. Starting at 15’ with a nice sloping reef down to 110’, it is a great dive site for all levels. Check out the Val Bomber and Barge Reef – both nearby.
