Part of Guam's Territorial Seashore Park, the overlook provides a window into the island's volcanic origins. From this vantage point, visitors can observe the unique rock formations, including the pillow lava of Attelong Acho (Black Rock) to the north, formed by ancient underwater eruptions. In the distance to the south, Cocos Island is visible off the coast of Merizo village. The coastal area around Cetti Bay has a rich history, inhabited by Chamorros for approximately 3,000 years. Latte stones and pottery shards found in the area serve as evidence of this ancient civilization. The Spanish later established a road system that passed through Cetti Bay, connecting Hagåtña to Umatac. Today, Cetti Bay Overlook is easily accessible and requires no extensive hiking, making it a favorite for tourists and locals seeking a quick immersion in nature. The slopes surrounding the bay are covered in grassland, savanna, and coconut trees, with a ravine forest concealing Cetti Falls.
