Diving Guide to Ritidian Point

About Ritidian Point

Ritidian Point at the far northern tip of Guam is a pristine marine reserve offering some of the clearest water and healthiest coral ecosystems on the island. The protected status of the reserve has created an underwater sanctuary with crystal-clear visibility frequently exceeding 40 metres, extensive coral gardens featuring giant clams, abundant sea turtles, and dense populations of reef fish. The outer wall provides advanced diving with strong currents attracting larger pelagics, while the calm inner lagoon is ideal for beginners and snorkellers. The Ritidian area is part of the Guam National Wildlife Refuge, ensuring strict environmental protections that have preserved one of the most biodiverse marine environments in the western Pacific. Above water, the dramatic limestone cliffs and pristine white sand beaches create a stunning backdrop for the diving experience. The relative remoteness from the main tourist areas means fewer divers and a more exclusive underwater encounter. Ritidian Point represents the pinnacle of Guam's marine conservation efforts and offers divers a window into what healthy Pacific coral reefs looked like before widespread development.
