Many locals consider this to be the best shore dive on Guam. It's a sandy beach at the North end of the main tourist town (Tumon). An old WW2 gun is tucked away at one corner. There's a shallow reef extending out from the beach for about 100 meters before it drops off. This reef is very shallow and unless it's dead calm, it can be dangerous to try and swim across it. In the middle of the beach there's a slightly-deeper channel with some small metal pipes running out to the drop-off. This is the entry/exit point. We swam out above the pipes, but some people walk out for most of the way on the pipes. As the water deepened, we descended to a slope of hard corals going down to over 100 feet deep. I went down to about 110 feet deep and the end of the reef seemed to be about 130 feet deep. Visibility was about 100 feet. A white-tip reef shark swam past in the distance. There was a good variety of smaller fish. I'm not a local expert so I didn't know most of their names. There was a mild current running along the slope. I don't know how strong it can get.
