Saona Island lies twenty-two kilometres south of the mainland Dominican Republic, a seven-thousand-hectare wedge of coral sand and mangrove lagoon enclosed within Cotubanamá National Park since 1975. No permanent settlement exists on the island; a rotating crew of park rangers and a single beachside restaurant operate under strict conservation protocols. The absence of roads, hotels, and commercial development preserves conditions that vanished from neighbouring coasts decades ago: water clarity exceeding thirty metres, nesting grounds for hawksbill and loggerhead turtles, and a shallow sandbar—locally called Piscina Natural—that stretches two hundred metres into the Caribbean at knee depth. The island entered popular awareness in the 1980s when location scouts selected its eastern shore for a rum advertisement, but mass tourism arrived only in the early 2000s with the expansion of Punta Cana resorts. Today, approximately three hundred thousand visitors per year cross the Mona Passage by catamaran or speedboat, making Saona the most-visited natural site in the Dominican Republic. The five-dollar conservation fee, introduced in 2018, funds patrol vessels and turtle monitoring programs administered by the Ministry of Environment. A Saona Island private boat tour departs between 07:00 and 09:00 to avoid the midday influx of group tours. Most charters follow a two-stop itinerary: first the natural pool, where passengers wade among starfish in water that remains translucent even at midday, then the main beach at Playa Palmilla or Playa Canto de la Playa, where the sand holds a fine talc texture rarely found on volcanic islands. The catamarans accommodate eight to fifteen passengers; speedboats carry six to ten and complete the crossing in thirty minutes rather than ninety. Lunch—grilled fish, rice, plantain—is prepared on-site by park-licensed vendors. The marine ecosystem around Saona supports seventy-four species of coral and more than two hundred fish species, mapped in detail by the Dominican Reef Survey between 2012 and 2019. The mangrove channels on the island's western edge serve as nursery habitat for juvenile snappers and barracuda. Seasonal closures during turtle nesting periods—May through October—apply to specific beach sections but do not affect tour access to the primary landing zones. The park's no-take fishing rules and boat speed limits have allowed reef recovery measurable by satellite imagery over the past fifteen years.
