Snorkeling and Scuba Diving at Piti Bomb Holes Preserve

At the end of the pier is a round, hollow building, with windows UNDER WATER. Entry into this building is not free, but is the ideal chance for non-swimmers to watch & photograph you while you're diving. Entry is via the beach, and a long walk in shallow water alongside the pier. Around 3/4 of the way out, the bottom becomes sandy and filled with pleasant finger corals. Light is abundant, and depths reach no more than 30'. You are more than welcome to "buzz" the windows of the manmade underwater building, and look at the displays set up on "windowsills" there. Excellent for non-divers, snorkelers, night diving...anything. Aside from the long walk through shallow water, this is a nearly perfect, utterly tame and safe, relaxing dive. Drive South-East from Tumon Bay. Pass Hagatna (the capitol city) and continue until you pass MDA, a large red barn like dive shop on the left side of the road. You'll see a looooong manmade pier on the right, and a large SCUBA/restaurant/wedding resort across the street from the pier. Along the beach adjacent to this pier is a ribbon like parking lot, adequate for 60 cars. There're pavilions with benches, and a stinky bathroom.

This is probably the most accessible 'safe' dive site on Guam other than Gab Gab on the Naval base. Nice public park with outdoor showers and restrooms. The walk over the shallow reef is long and somewhat tedious (and hot)...the bomb holes are more accurately called bomb craters. There are hundreds of large bomb craters starting just a few feet beneath the surface, with the deepest ending at the base of the Aquarium around 30 feet deep or so and the shallowest only a few feet deep. Judging by the size of the craters (and my experience with WWII-era ordnance on Kaho`olawe, Hawaii), I'd say that the majority of craters were made by at least 1,000-pound bombs or more than one 500-pound bomb. It is my understanding that these craters were created during the U.S.-lead liberation of Guam from Japanese occupying forces during WWII. Many of the beaches along Guam still contain ordnance and ordnance-related remnants. [If you like your fingers and toes, refrain from picking up anything metal from the water.] The shallow craters are somewhat annoying (up, into, then up and over). The best crater is the largest, at the Aquarium. Anemones, jack, clownfish, and lots of others (including people in the aquarium) make this the most interesting part of the dive. I tried to make it past the barrier reef, but it's very far out, and I tired long before reaching deeper waters. Recommended for beginners through advanced divers who are in relatively good shape and need a good workout!
