Cayo Arena offers schools of tropical fish that can also easily be seen in shallow turquoise waters, making this spot a paradise for snorkeling fans; the area boasts some of the most abundant marine life in the DR, with corals and sponges, and schools of tropical fish swimming around your feet.
Sitting 10 kilometers (six miles) northwest of the Bay of Montecristi, Los Siete Hermanos consist of seven sandy cays–Toruru, Muertos, Ratas, Terrero, Monte Grande, Monte Chico, and Arenas. Formed by coral sands, they offer a world of beaches, underwater exploration, and wildlife. Around the cayes’ shores, you’ll spot cacti, iguanas, and crabs. Underwater, submerged forests, sandy bottoms, and large rocky walls make this area a one-stop site for snorkeling, day or night diving–at just three meters (10 feet), making it accessible to beginners. And unlike other diving spots in Montecristi, you can explore on windy days.
The seven cayes are also the DR’s primary nesting site for boobies–the season runs from late May to early September–and are an ideal spot for watching migratory and native birds.
