Double Reef (Clownfish Rock area) Located on the Northern sector of Guam. It's kind of a hideaway cove that is protected from the winter winds most of the time. Getting there may be another story, especially coming up the coast from Agana Marina or Apra Harbor. There is a frontal protective reef that lies around the outer edge of this neat little point. This reef lies just below the surface and if you don't know where it is, don't be zooming 90 mph across the water in your boat. At times it's only inches deep. Mooring your boat on the inside of this reef there are many sand patches below. Dropping an anchor in a sand patch is preferable than breaking up the coral. In the middle of the largest sand area (at about 50 feet) is a small reef/rock about the size of a small bedroom and rises about 3 feet from the sand. As you are swimming toward the rock (from the old mooring) you will see a semi overhang on either side of the reefs going South. Within the rock you will find a large sea anemone and it's swamped with hundreds of clownfish. A medium size octopus was also there the last time I visited there. If you're careful and swimming very low in the sand you will come upon a maze of garden eels when approaching clownfish rock from the North. Don't breath excessively as your regulator bubbles will scare the eels back down their holes. Pretend you're a sniper and crawl along the sand until you can get close to the eels for a good camera shot. Going North from the rock along the left side of the large towering reef the slope gradually drops off. Deeper and deeper and soon you will come upon some neat cracks and mini crevices that are home to all kinds of colorful fish. The drop-off is so very gradual that you have to swim several hundred yards to get down to 100 feet. At 100 feet you will come to the end of the reef and look out into a sand covered outerspace. I like it down there and I have seen some big sharks, napoleanfish, grouper, and a stingray. When your deep time is up, head back up the big reef instead of following your previous decent in the sand (Go to the left). The reef is covered with tons of interesting stuff and the incline will bring you up to shallower water faster. When you finally reach the area around the boat don't stop there unless you're very low on air. Instead head East and comb over all the small sand patches and cracks for shells, octopus, nuibranch and small pufferfish. You will come across some unusual white spotted moray eels and maybe even run into dolphins if you're extremely lucky. It's happened to me a few times but I never had my camera with me.
