12 International Eco-Travel Havens Captivating US Explorers

10. Palau’s Rock Islands

Palau’s Rock Islands are celebrated for exceptional marine biodiversity and rigorous eco-protection measures. As the first country to require a “Palau Pledge” from visitors, travelers agree at entry to uphold conservation values and respectful conduct. The marine sanctuary encompasses vast coral reefs, supporting everything from manta rays to rare clams, making it a wonderland for divers and snorkelers. Eco-friendly tour operators and locally managed lodges ensure tourism benefits both nature and communities. For US travelers, reaching Palau involves connections through Guam or Manila, and the dry season from November to April delivers the best conditions for water activities. The level of marine preservation is matched by the welcoming spirit of Palauan people, many of whom are directly involved in sustainability projects. Visitors leave knowing their trip supports a pioneering national approach to eco-tourism.
