Legacy Journeys

Europe’s Western Balkans

Take in dream-like rivers, stunning natural beauty and the rich cultural heritage of Croatia and Bosnia and Herzegovina.

September 5-12, 2026 

Water leads the way in the Western Balkans. During this debut Legacy Journey to Croatia and over the border into Bosnia and Herzegovina, we’ll explore scenic countrysides and quaint towns that are largely a secret to the rest of the world. Hear from TNC experts working on the ground to protect the region’s most ecologically significant natural landscapes and some of Europe’s last free-flowing rivers. From waterfalls to underground streams and vast wetlands, you’ll learn about environmental challenges and opportunities, as well as the ways that TNC can play a role in safeguarding these global hot spots for unique plants and animals.

Highlights

  • Float along the sparkling Kupa River in a traditional Žitna lađa boat to enjoy a unique perspective of Croatia’s forests, monasteries and local wildlife.
  • Venture into Plitvice Lakes National Park to see unique tufa formations of hollow, porous rock that, over millennia, have created natural barriers to form the park’s globally significant system of lakes.
  • Immerse yourself in the natural beauty and cultural heritage of the Japod Valley as you explore its cascading waterfalls and medieval fortresses.
