If you come to Guam for tourism, you must come to the northernmost nature reserve of Guam. Although the road is hard, you have to test your driving skills to avoid water puddles. It was a long-range communication radar station of the U.S. Navy during the Cold War, near Anderson Air Force Base, and now it is the front position of the U.S. to encircle China. After the abandonment of the radar station, the U.S. Army surrendered part of its land to set up a nature reserve, but it is still owned by the U.S. Army, and warning signs are seen everywhere. Because of the long period of military control, there are also green turtles, hats and other cherished animals, unfortunately, bad luck, can not see, only the migrant crabs running all over the ground.
