Saona Island ranks 1st on the list of the most beautiful islands in Dominica. This is a famous island located on the Dominican Republic's southeast coast. This island is hard to top for magnificent natural beauty and crystal-clear seas for snorkeling or simply sunbathing along the coast. The oceans around the island are teeming with biodiversity, with numerous types of birds and tropical marine fish, and there are extensive regions where natural sandbars offshore reduce the depth to only a few feet. Smaller speedboats stop for guests to relax in the waist-deep shallows where they dive and explore the region's starfish farms. Coral reef ecosystems with outstanding marine diversity may be found on and around Saona island, attracting both snorkelers and scuba divers.

Saona has more to offer than most other islands off the coast of the Dominican Republic because it is larger. Palmilla Beach is a beautiful length of the beach with shallow waters ideal for families. If you've had your fill of the sea and sand, head to Cotubanamá National Park. A short stroll will lead you to Cueva del Puente (Bridge Cave), where you can discover old artwork.

Location: La Altagracia province, south-east coast of Dominica.

Catalina Island (Isla Catalina) is a renowned tourist destination off the coast of the Dominican Republic. The island is only 9.6 square kilometers in size and is home to a variety of ecosystems such as sand dunes, mangroves, and reefs. The island is made of coral stone and has three overlapping plateaus. The island's highest point is only 60 feet above sea level.

Cayo Arena, off the northern coast of the Dominican Republic, is a tiny whisper of a Caribbean island that scarcely exists. This sandy dollop emerging from the coral is 2,100 square feet in size—less than a tenth of an acre of beautiful, brilliant white sand. The island itself is underdeveloped, save for a few thatched-roof houses, and snorkeling in the quiet, blue lagoon is a great chance to meet curious Caribbean fish. Cayo Arena, often known as "Paradise Island," is a tropical paradise where sand, sky, and crystal clear water combine to create a Caribbean enclave that appears too lovely to be real.

The beautiful coral reefs that encircle Cayo Arena are more appealing than the golden sand. The calm, turquoise seas around the island frequently allow for visibility of more than 10 meters, allowing snorkelers to explore the wonderful underwater world of brilliant coral, schools of fish, and other sea life.

When you are hungry, there are a few modest beach restaurants on Cayo Arena that serve freshly grilled seafood, such as grilled tuna and octopus. The island is easily accessible because it is located just off the northwestern coast of the Dominican Republic. It entails a trip to the Punta Rucia dock. You can board a boat that will transport you to the island in less than 30 minutes from there.

Cayos Siete Hermanos is one of the Dominican Republic's most remote and least frequented islands. Cayos Siete Hermanos is a group of seven sandy cays located 10 kilometers (six miles) northwest of the Bay of Montecristi: Toruru, Muertos, Ratas, Terrero, Monte Grande, Monte Chico, and Arenas. They are made up of coral sands and offer a world of beaches, underwater exploration, and wildlife. Cacti, iguanas, and crabs can be found on the cayes' coastlines. Underwater, submerged woods, sandy bottoms, and big rocky walls combine to create this location as a one-stop-shop for snorkeling, day or night diving–at only three meters (10 feet), it is accessible to beginners. And, unlike other diving places in Montecristi, you may go diving even on windy days. The seven cayes are also the principal nesting site for boobies in the Dominican Republic (the season spans from late May to early September) and an excellent location for seeing migratory and native species.

Because of its remote position, it is best to book a tour to get to Cayos Siete Hermanos. Be warned that the island has no shade, so plan appropriately — bring a parasol and, at the very least, a hat!
