Wilderness Landscape & Natural Heritage
Tumon Bay Marine Preserve encompasses the sheltered waters of Tumon Bay, located on the western coast of Guam, the largest island in the Mariana archipelago. The preserve features an extensive coral reef system and seagrass beds, providing critical habitat for a wide array of marine species including reef fish, sea turtles, and various invertebrates. The bay’s shallow waters and calm conditions create an ideal environment for both conservation and recreation. Established to maintain the health and biodiversity of Guam’s coastal ecosystems, the preserve supports efforts to curb overfishing, habitat degradation, and water pollution. Historically, Tumon Bay has been vital to local Chamorro culture as a source of sustenance and a community gathering place. Today, it remains a favorite spot for locals and tourists alike, offering easy access to snorkeling, scuba diving, paddleboarding, and eco-tours. Notable landmarks include the vibrant coral bommies and the underwater caves near Matapang Beach, as well as the nearby Tumon Bay beach park that offers family-friendly facilities. Visitor appeal lies not only in the abundant marine life visible just beneath the water’s surface but also in the scenic beauty and warm tropical climate year-round. The preserve plays an important role in Guam’s marine conservation efforts, promoting sustainable tourism and environmental education.
