A Caribbean native shares the under-the-radar islands you should visit if you're trying to avoid tourists

Celestina moved to St. Martin 19 years ago.

"It feels more like home than any other place I've been to," she said.

It's compromised of two countries: the northern French side, Saint Martin, and the southern Dutch side, Saint Maarten. Celestina said traveling to the opposite side of the island is like visiting an entirely different country.

"If I want to get away, I can easily just drive over to the French side and feel like I'm somewhere else," she said. "It's a gem in the Caribbean."

Celestina noted that in recent years, the island has become more popular with tourists and cruise ships. However, there are still lesser-known places across the island that visitors can discover.

She suggested skipping places like Mulley Bay Beach or Orient Beach and opting for lesser-known beaches, such as Petite Plage Beach, or hiking to Happy Bay Beach.

Tintamarre Island is a remote island off the coast of St. Martin.

While you won't find any hotels, restaurants, or shops, it's the ideal remote day trip.

The island is just two miles away from St. Martin's coast. Visitors can snorkel with sea turtles, explore the island's red rock cliffs, or enjoy its sandy beaches.

Celestina recommended packing a picnic because there aren't spots to buy food or drinks on the island, but visitors will be welcomed by wind, sandy, and a serene environment.

From the coast of St. Maarten, Celestina can spot Anguilla, and it's been calling her name ever since the territory closed its borders in March.

The British overseas territory is filled with remote beaches. Since the island doesn't cater to mass tourism, it's much less crowded than some of its neighboring islands.

The entire coast of the award-winning island is public land, and since few travelers journey to the island, you almost always have the beach to yourself, Celestina said.

"Especially in the summer, it would be normal for you to be on one of the top beaches in the world by yourself," she said. "It is an absolutely gorgeous place, the people are nice, and it's never crowded."

The island of Saba topped Celestina's list of lesser-known Caribbean destinations.

"Saba is one of those islands that's quickly overlooked because it doesn't have beaches, but its underwater world is famous," she said.

The island gets its nickname, the "unspoiled queen," from its pristine nature. It's home to rainforests, coral reefs, and the dormant Mount Scenery volcano.

Celestina said that Aibonito is filled with "waterfalls, rainforests, and a little bit of chilly weather."

Inland Puerto Rico is much more isolated than nearby towns like Old San Juan, but visitors still get the best of both worlds.

From Aibonito, beaches are still only an hour away. The area is known as Puerto Rico's horticultural hub, where local businesses sell an array of beautiful flowers, plants, and fruit trees.

In Aibonito, a trip to Cañón de San Cristóbal is a must. It's a 5.6-mile canyon teeming with waterfalls, springs, and a diverse range of plants and flowers.

Celestina said that visitors looking for remote areas in the Caribbean should head to Curaçao's western side.

Curaçao is known as a city island of the region, so it can get pretty crowded, but on the western side, visitors will feel like they're in a more isolated place.

This area known as Banda Abou has breathtaking beaches, as well as churches, museums, and historic architecture.

Or you can head to Little Curaçao, which is a tiny sandbank off the coast of Curaçao.

It's a quaint island with a lighthouse, which makes it ideal for a remote day trip or overnight camping excursion.

While its sister island, St. Kitts, is more well-known, Nevis is home to many beautiful spots.

The island contains more than resorts. Sprinkled throughout the tropical land are dozens of waterfalls and volcanic beaches.

"I don't think people realize how much you can do on Nevis," Celestina said. "It's a quiet little place that's really beautiful."

While most visitors flock to Nevis during the winter to escape the cold, consider visiting during the off-season, when hotels and Airbnb rentals often offer lower accommodation rates.

The island is filled with centuries-old sugar mills and other spots teeming with history. Celestina added that she has never had a bad meal on the island and that all the locals were extremely welcoming.

"It's not one of the first islands you think about when you say 'Caribbean,'" Celestina said.

Dominica is known as the Island of Nature because it's filled with rainforests and picturesque waterfalls.

It's a destination that's perfect for people who love adventure, and it's not as popular as some of the nearby islands.

While you might not spend your vacation on Dominica lounging on white sandy beaches, visitors can fill their itineraries with diving, hiking, and relaxing hot springs, all without crowds of tourists.

St. Barts, also called St. Barthélemy, is a French-speaking Caribbean island.

It's known for being a luxurious destination, but Celestina said that in less-popular travel times, it can be a more approachable place to visit.

"When it's out of season, it's more accessible to everybody," she said. "And a lot of people tend to forget that."

If you're not there during high season, restaurants and shops might be closed, but you'll have the island to yourself, Celestina said. All 14 of the island's beaches are open to the public, and they'll likely be empty during the off-season months.

According to US News, the best times to visit the island are between April and June, when fewer tourists are there but the weather is still calm.

"You really get to see the island," Celestina said.
