17 Best Places to Travel in 2026 That Aren't Completely Overrun With Tourists

3. Raja Ampat, Indonesia: The Crown Jewel of Marine Biodiversity

Raja Ampat, meaning "Four Kings" in Indonesian, represents the epicenter of global marine biodiversity and offers some of the world's most pristine diving and snorkeling experiences without the crowds that plague other tropical destinations. Located off the northwest tip of Indonesia's West Papua province, this remote archipelago encompasses over 1,500 small islands and harbors an astounding 75% of all known coral species and more than 1,400 species of fish. The region's isolation and the Indonesian government's commitment to marine conservation have created a sanctuary where travelers can witness healthy coral reefs, manta ray cleaning stations, and schools of fish so dense they block out sunlight. Local communities have embraced sustainable tourism through the "sasi" traditional conservation system, where certain areas are periodically closed to fishing and tourism to allow marine ecosystems to regenerate. Visitors can stay in eco-friendly resorts run by local communities, participate in coral restoration projects, and explore hidden lagoons accessible only by traditional boats guided by indigenous Papuan navigators. The region's limited infrastructure and requirement for specialized diving certifications naturally control visitor numbers, ensuring that this underwater paradise remains pristine for future generations while providing local communities with sustainable income alternatives to fishing and logging.
