Fish Eye Marine Park
818 N Marine Corps Drive, Piti, Guam 96915-5524
Fish Eye Marine Park is Guam’s best-known underwater observatory experience, offering a dry-view window into Piti Bay’s reef life. The official listing emphasises its observatory as the only facility of its kind in Micronesia, along with the pier, upper deck and marine views that make it appealing even for non-swimmers. It works especially well as a family-friendly stop because the main experience does not require getting into the water. Beyond the observatory, the park’s setting beside the marine preserve gives it a sense of place that is both scenic and educational. It is an easy fit for half-day itineraries and a good counterpoint to Guam’s more land-based heritage sites.
