Overview
Cetti Bay, located near Umatac on the southwestern coast of Guam, is a captivating blend of natural beauty and historical significance. This oceanic bay is part of Guam's Territorial Seashore Park and is listed on the National Register of Historic Places. The name applies both to the bay itself and the surrounding historical site.Archaeological evidence suggests that the coastal area around Cetti Bay has been inhabited by Chamorros for approximately 3,000 years. The ancient Chamorro village of Jati once stood near the bay's north shore, leaving behind latte stones and pottery shards. These remnants offer a tangible connection to Guam's pre-colonial past. The Spanish later created a road system that passed through Cetti Bay, connecting Hagåtña with Humåtak.Today, Cetti Bay is a popular destination for those seeking both natural beauty and a connection to Guam's history. The bay offers opportunities for hiking, snorkeling, and fishing. The surrounding area features grassland, savanna, coconut trees, and a ravine forest that hides Cetti Falls. The twin hills north of the bay, known as Attelong Acho or Black Rock, are pillow lava formations from ancient volcanic eruptions, adding to the geological interest of the area.To access the bay by land requires a hike along the shore north from Humåtak or south from Sella Bay. Cetti Bay Overlook provides panoramic views of the bay and surrounding landscape.
