12 International Eco-Travel Havens Captivating US Explorers

5. Slovenia’s Triglav National Park

Nestled in the Julian Alps, Slovenia’s Triglav National Park is a European leader in sustainable tourism and conservation. The park’s crystal-clear rivers and forests are home to native chamois, lynx, and golden eagles, creating brilliant opportunities for hiking, cycling, and wildlife spotting. Surrounding communities in the Bled/Bohinj region have crafted award-winning green tourism programs, encouraging travelers to choose eco-friendly stays and local food producers. Triglav promotes rewilding, especially along mountain river corridors, which has earned praise from international conservation groups. Getting to the region from the US typically involves flights to Ljubljana, with trains and affordable buses connecting onward. The best periods for temperate hiking and festivals span from May to September. Practices like “Leave No Trace” and well-marked trails make exploring both easy and ethical, while supporting a proud culture of stewardship and sustainability.
