National Parks Traveler Podcast | Polluting Parks With Light

National Parks Traveler Podcast | Polluting Parks With Light

Author: Kurt Repanshek April 12, 2026 Duration: 41:35

You might not entirely appreciate the wonders and majesty of national parks unless you venture out after dark and gaze up at what often is referred to as the other half of the national park system. The view can be quite dazzling, with planets, stars, the Milky Way, and for the lucky, a comet or shooting star.

Sadly, not every park offers such dazzling views. Light pollution reaches more than a few national parks, and can really infringe on your nighttime enjoyment of the parks.

Gavin Heffernan is among those park travelers who are troubled by light pollution. He's a California-based photographer with a unique long-form time lapse style. And he's hoping this approach brings a fresh awareness to the wonders of night skies in the national parks and creates advocacy to fight light pollution and the damage it wreaks on natural habitats. 


There's a world of stories waiting beyond the park entrance sign, and the National Parks Traveler Podcast is your audio guide to them. Led by Kurt Repanshek, this series goes deeper than trail maps and visitor statistics. It connects the natural wonder you experience firsthand with the crucial, often unseen work happening behind the scenes-the science informing conservation, the cultural histories embedded in the landscape, and the policy decisions that will shape these places for future generations. As the audio companion to the editorially independent nonprofit media organization, this podcast delivers a thoughtful blend of on-the-ground reports, interviews with researchers and park staff, and nuanced discussions about the challenges and triumphs in managing protected areas. You'll hear the sounds of the parks and the voices of the people dedicated to them. Each episode is an invitation to better understand the complex tapestry of ecology, history, and society that makes every national park far more than a scenic destination. Tune in for a regular dose of insight that will deepen your appreciation and perhaps even shape your next journey into America's most treasured public lands.
