Marine protected area — one of the world’s most celebrated community-managed marine sanctuaries, established in 1982 through a community-led conservation effort (with support from marine biologists including Dr. Angel Alcala and Silliman University’s Marine Laboratory) that turned an overfished reef into one of the most-cited success stories in marine conservation globally. A no-take zone with a fringing reef extending roughly 500m offshore. Roughly 7km off the southeastern tip of Negros, about a 40-minute boat ride from Zamboanguita or Malatapay Port. CURRENT STATUS (time-sensitive): at least one 2026-dated source reports the core sanctuary zone is under rehabilitation with diving and snorkeling temporarily prohibited there — confirm current access status before publishing specific snorkeling/diving claims, since the rest of the island’s dive sites remain accessible even if this is accurate. Island itself has only 3 hours of electricity nightly (traditionally 7-10pm) and very limited WiFi — worth setting expectations for visitors.
