You dream of most islands because of their beautiful beaches, relaxing resorts, and laid-back vibe. But others are fascinating because they offer few if any of those things—yet. Here are five undeveloped islands to keep an eye on in the future.

Kahoʻolawe: Though Hawaii is considered a bucket-list destination, few people have visited—or even heard of—all eight of its main islands. Barren Kaho’olawe is about to be brought back to life.

Aves Island: You may think you know all of the best snorkeling spots in the Caribbean, but few people have even heard of this rock near Montserrat and Dominica.

Kerkennah Islands: Seven islands off the coast of Tunisia are known for their sheltered bays and little villages, colorful boats and long-established fishing methods. Plus their simpler way of life.

Tromelin Island: An island in the Indian Ocean keeps popping up in the news, but you’re more focused on its large sandbank, boobie nesting sites, and giant sea turtles than the investigation into a missing airplane.

Kamaran Island: The islands in the Red Sea are famous for their two moons. But until pirates, smugglers, and even worse leave the area alone, you’ll have to keep dreaming about visiting Yemen.
