13 Best Puerto Rico Islands

Puerto Rico is not just one island, it’s a few! And if you’ve never been to any of the Puerto Rico islands outside the mainland, you’re missing out big time.

Puerto Rico is an archipelago, composed of the main island and other 143 smaller islands and cays that hide some of the best things to do in Puerto Rico. 

Puerto Ricans (like myself) love taking trips to these hidden tropical paradises. From an island with a bioluminescent bay to the “Galapagos of the Caribbean”, these are the Puerto Rico islands you should visit.

13 Best Puerto Rico Islands

Vieques

But the most popular attraction in Vieques is kayaking Mosquito Bay, the brightest bioluminescent bay in the world. Families can also enjoy horseback riding and cycling in this small Caribbean paradise.

Culebra Island

A Caribbean paradise home to a few of the best beaches in Puerto Rico  

📍 Google Maps

Culebra is the perfect place in the Caribbean Sea to escape the rush of the modern world. This Puerto Rico island, part of what’s known as the Spanish Virgin Islands, doesn’t have any shopping malls, brand stores, or mega-hotels. Instead, it offers a laid-back relaxing atmosphere for true beach lovers. 

Culebra’s beaches sum up to 111 white sand beaches praised for their visibility and breathtaking vistas. Culebra is also that dream destination where you can swim side by side with green sea turtles. Scuba diving enthusiasts shouldn’t miss it, as Culebra’s coasts hide shipwrecks, underwater caves, and coral reefs with colorful wildlife.

Gilligan’s Island

Snorkel in the clearest waters of the Caribbean

📍 Google Maps

The island is a mangrove island with crystal clear waters that lets you see pools of fish swimming with the naked eye. The waters surrounding Gilligan’s Island are so shallow that they are safe for all the family. Adventure seekers can choose to kayak from Guánica or take a water taxi from the city.

Palomino Island

📍 Google Maps

If you’re not staying at El Conquistador, you can reach Palomino through a private boat tour. Palomino is a great alternative to Icacos if you want to visit a cay, without having to carry everything for a beach day trip.

Icacos

Party on the shore of this popular cay

📍 Google Maps

But, Icacos is particularly popular among party lovers. During the weekend, multiple catamarans anchor on Icacos shore simultaneously and all visitors meet up in the water to swim, talk, and dance to the music. 

👉 Staying in San Juan? Icacos is one of the top day trips to take from the capital city. Check out these other awesome day trips to take from San Juan.

Desecheo Island

Discover the underwater world of a forbidden island

📍 Google Maps

As a result, the island itself is forbidden territory, as it’s believed dangerous ammunitions are everywhere. But, if you’re into scuba diving, you can’t miss the underwater caves of Desecheo, where the most colorful marine life comes together. Considered one of the best things to do in Rincón and Mayagüez, you can only visit Desecheo through Taino Divers.

Culebrita

Swim with turtles on the secluded beaches of Culebrita

📍 Google Maps

Playa Tortuga, also known as Culebrita Beach, is a nesting site of endangered sea turtles. It’s said the island got its name from the large population of turtles you could find on its shores and waters. So, if you’re dream is to swim with turtles, you can see it come true at Culebrita. 

Isla de Mona

Camp in the Galapagos Islands of the Caribbean

📍 Google Maps

Isla de Mona is located off the west coast, right between Puerto Rico and the Dominican Republic. This unoccupied nature reserve hosts stunning beaches, coral reefs, and caves with pre-Columbian petroglyphs. It’s a true paradise of natural beauty where you’ll disconnect yourself from civilization.

But, visiting Mona Island is not for the faint of heart. The island doesn’t have facilities or phone signals, and the boat ride from Puerto Rico through the Mona Passage takes about 4 hours. There isn’t potable water, there are venomous plants around the island, and the arid dry weather could dehydrate you quickly. It’s an adventure for outdoor experts only.

Isla Mata La Gata

A beautiful cay with a man-made pool

📍 Google Maps

Mata La Gata is one of the enchanting islands that form La Parguera Nature Reserve, and it’s one of the few Puerto Rico islands with mangrove trees. But, different from many other islands, Mata La Gata sports picnic tables, where you can spend a nice afternoon with your family. 

Caja de Muertos

A coffin-shaped small island with blue flag beaches

📍 Google Maps

Playa Pelicano is the most popular beach on Coffin Island, with calm turquoise waters that make every visitor want to stay there for the rest of the day. Outdoor lovers can also adventure through the island’s hiking trails to reach Caja de Muertos’ lighthouse ruins.

Cayo de Tierra

A small cay easily accessible from Vieques

📍 Google Maps

Cayo Caracoles 

A tiny island on the south coast

📍 Google Maps

Another cay that is part of La Parguera Nature Reserve is Cayo Caracoles. This small cay doesn’t have any shore, beach, or dock. Although you can’t exactly enter the mangrove cay, it’s a popular destination among Puerto Ricans for its shallow crystal clear surroundings. 

Because it doesn’t have any shore, visiting the cay means always being inside the water, whether you’re sitting, sunbathing, or snorkeling. 

Cardona Island

An island with a historical lighthouse and a beautiful beach

📍 Google Maps

Isla Cardona is often outshined by its neighbor, Caja de Muertos. But, visiting Isla Cardona is one of the best things to do in Ponce. This island boasts a historical lighthouse, a crystal clear beach, a green landscape, and a pebbly shore where visitors like to build rock towers. 

Cardona Island has picnic areas, but no facilities, so beach buffs need to bring everything for a day trip. You can only reach it by kayak, or by booking a tour through Waterland Adventure Puerto Rico.
