12 International Eco-Travel Havens Captivating US Explorers

9. Azores Archipelago, Portugal

Scattered across the mid-Atlantic, the Azores are Portugal’s premier example of sustainable island living. The archipelago has earned widespread praise for marine conservation, geothermal energy, and responsible whale watching. São Miguel and Pico islands in particular have implemented protected areas for dolphins and sperm whales, with locals guiding tours that fund conservation outcomes. The region is recognized by European green tourism bodies for its low-carbon travel options, such as electric vehicle rentals and eco-friendly accommodation. Travelers from the US typically connect via Lisbon, with mild conditions year-round—spring and early fall bring vibrant wildflowers and fewer visitors. Americans cite the Azores’ warm hospitality and forward-thinking approach as highlights, while robust conservation efforts ensure that future generations can enjoy the same untamed beauty.
