National Geographic's journalists, explorers, scientists and photographers have scaled the world's highest peaks, probed the depths of our oceans, and explored just about every country in the world. Each week, they share their adventures and their insights during a fascinating hour of radio conversation. Whether they're in Antarctica, Tibet, Afghanistan—or just around the corner—we bring you their best stories and most compelling observations.

Join host Patty Kim each week for provocative interviews that will fire your imagination and transport you to new heights.
