Discover more about Sella Bay

Sella Bay, located on Guam's southwestern coast in Humåtak, is more than just a scenic spot; it's a place where history and nature intertwine. Originally known as Sidya, this area was a Chamoru village that played a role in the Spanish-Chamoru Wars of the 17th century. Sidya sided with the Spanish against its neighbor Aty (present-day Cetti Bay) and was notable as one of the few villages where the Spanish recognized the power of a female leader, a Maga'håga.During the Spanish colonial era, a road was constructed to connect Humåtak, then a major port, with Hagåtña, the capital. A key feature of this road was the Spanish Bridge at Sella Bay, a testament to the island's history. In the 1970s, Sella Bay was the focus of a campaign against U.S. military plans to build an ammunition wharf there. A coalition of activists successfully opposed the development, preserving the area's historical and natural value.Today, Sella Bay is a natural preserve offering hiking trails with access to both historical sites and natural landscapes. The Sella Bay Trail descends through trees, crosses a stream, and opens to meadows with coastal views. The trail leads to Sella Bay beach, where you can explore the shoreline and see a Spanish bridge. The hike to Sella Bay is considered medium level, with a mix of Chamorro artifacts, Spanish architecture, and diverse scenery.
