Podcast with Charlie Walker, “On Thin Ice”

In February 2022, British explorer Charlie Walker flew to Siberia’s Sakha Republic to walk a thousand miles up frozen rivers to the Arctic Ocean, through Earth’s coldest inhabited region. Days later, Russia invaded Ukraine. Tamping down his concerns, he continued on his journey, meeting indigenous people and ice road truckers along the way. Yet his trip ended in fear and confusion, with an arrest and a month in a Yakutsk jail.
The story is told in his new book, On Thin Ice: An Explorer’s Memoir of Siberia, Surveillance and Survival (Duckworth, June 2026), which was reviewed for the ARB by Peter Gordon in June 2026. You can read the full review here.
Charlie is an award-winning explorer, author and international keynote speaker. He has travelled over 60,000 miles by foot, horse, raft, bicycle, ski and dugout canoe, in places as varied as the Tibetan plateau, the Mongolian steppe, the Congolese jungle, the Arctic tundra, the highlands of New Guinea and the Sahara desert. He is an elected Fellow of the Royal Geographical Society, a Scientific Exploration Society Explorer Award winner, and the author of Through Sand & Snow and On Roads That Echo.
