Whether you want true seclusion, eco-adventure, or authentic local flavor, these 12 hidden islands are worth adding to your travel bucket list right now.
Carriacou
A peaceful gem north of Grenada, Carriacou is where life slows to a crawl. With uncrowded beaches, traditional boat building, and rich cultural festivals, it’s perfect for travelers who want a slice of authentic island life. Snorkeling off Sandy Island is incredible and you won’t find large crowds here. It’s a great pick for anyone looking to disconnect from noise and connect with the sea.
Union Island
Part of Saint Vincent and the Grenadines, Union Island stuns with its jagged silhouette and warm island hospitality. A favorite among sailors, it’s also a great place for hiking, kitesurfing, and discovering tucked-away beaches. You’ll get a local vibe without the frills or crowds of bigger islands. The clear waters and lush hills make every photo look like a postcard.
Basse Terre
Located in Guadeloupe, Basse-Terre is a paradise for nature lovers. It’s home to the Guadeloupe National Park, the majestic La Soufriere volcano, and endless waterfalls. Unlike resort-heavy islands, this one gives you hiking trails, scenic drives, and raw beauty. You’ll find fewer tourists here, making it feel like your own private rainforest retreat beside the sea.
Martinique
French Caribbean flair meets laid-back island charm in Martinique. You can sip locally made rum, wander through colorful towns, and relax on quiet beaches. The island blends European style with Caribbean warmth. It’s not on most bucket lists, which makes it even more appealing for travelers who want good food, great views, and an uncrowded cultural experience.
Dominica
Known as the Nature Island, Dominica skips the tourist traps and focuses on raw, untamed beauty. Expect boiling lakes, natural hot springs, dense jungle hikes, and towering waterfalls. If you’re looking to dive or snorkel, the marine life here is outstanding. It’s ideal for eco-adventurers who want a challenge and reward without the commercial fluff.
St. Vincent
Often overshadowed by its glitzier neighbors, St. Vincent offers volcanic landscapes, black sand beaches, and friendly local towns. It’s also the gateway to the untouched Grenadine islands. Hike La Soufriere volcano or snorkel the reefs near Young Island. You’ll find authenticity, adventure, and room to breathe. Come for the nature, stay for the quiet.
St. Barthelemy
Often called St. Barts, this French island blends luxury with low-key charm. While it’s known for glam, many miss its peaceful, hidden coves and friendly cafés. The beaches are stunning, the roads scenic, and the shopping optional. Off-season, it becomes a quiet haven that feels more village than jet-set. It’s elegant, but never overwhelming.
St. Martin
Shared by the French and Dutch, St. Martin is rich in culture and diversity. Skip the busy beaches and explore the lesser-known coves, local markets, and fusion cuisine. The dual nationality gives the island a unique rhythm. You can relax on the French side, party on the Dutch side, or find somewhere in between that’s all your own.
Anguilla
If you love beaches but not crowds, Anguilla is your spot. It’s home to some of the Caribbean’s finest stretches of sand, with a calm, polished feel. You won’t find mega resorts, but you’ll find refined boutique stays and local BBQ shacks. It’s quiet, safe, and peaceful. Anguilla is the kind of place where time slows down and your mind clears.
Grenada
More than just beaches, Grenada is bursting with spice plantations, waterfalls, and rainforest hikes. Visit the chocolate factory, explore Fort George, or dive to the underwater sculpture park. The island feels alive with color, sound, and stories. Despite its appeal, it’s still often overlooked. That means more room for you to explore and enjoy.
Antigua
Antigua has 365 beaches, one for each day of the year, but few people know how easy it is to escape the resort bubble. Beyond the popular spots, you’ll find untouched coves, historical forts, and fishing villages. The island’s rhythm is calm, with just enough energy to keep it interesting. For sun, history, and sailing, Antigua quietly delivers.
Barbuda
Barbuda is the sleepy sister of Antigua, and that’s a good thing. With pink sand beaches and almost no crowds, it feels like your own private island. Visit the frigate bird sanctuary, snorkel untouched reefs, or simply do nothing. There’s no rush here, just long walks, calm waves, and starlit nights. For true escape, Barbuda is the answer.
