Off the northern coast of the Dominican Republic, near the quiet fishing village of Punta Rucia, lies a natural treasure that seems almost too perfect to be real: Cayo Arena, also known as Paradise Island. This tiny sandbar surrounded by crystal-clear waters and vibrant coral reefs is not only a visual paradise—it’s also a key spot to understand the ecological richness of the Dominican Atlantic coast.

📍 Where is Cayo Arena and How Do You Get There?

Cayo Arena is located offshore from Punta Rucia, about 2.5 hours west of Puerto Plata by car. To reach it, you take a speedboat from the docks at Punta Rucia or nearby La Ensenada. The journey is an adventure in itself: you cruise through mangrove channels, over turquoise shallows, and alongside sandbanks teeming with marine life.

What Makes Cayo Arena So Unique?

1. It’s a “floating” island

Unlike fixed landmasses, Cayo Arena is a shifting sandbank, formed by the movement of tides and wind. It has no vegetation or permanent structures, and its shape and size can change depending on weather and sea conditions. Sometimes, it even disappears temporarily.

2. One of the best snorkeling spots in the country

Surrounded by a vibrant live coral reef, Cayo Arena offers ideal snorkeling conditions. Tropical fish, sea urchins, starfish, and other marine creatures can be seen clearly thanks to the excellent water visibility.

3. A dream for photographers

Whether by drone or at sea level, Cayo Arena is incredibly photogenic. The contrast of white sand, layers of turquoise water, and the mountains in the background make it one of the Caribbean’s most Instagrammable locations.

Biodiversity Around the Island

Cayo Arena is part of a protected reef zone, essential for marine biodiversity. Nearby, the mangroves of La Ensenada act as natural nurseries for fish and shelter for both migratory and endemic birds.

During certain times of the year, lucky visitors might even spot dolphins on the way to the island.
