The Great Sand Dunes National Park and Preserve, designated as a Gold Tier International Dark Sky Park, offers exceptional night sky experiences that significantly enhance visitor satisfaction. A survey of 367 visitors in October 2023 found that 47% would reduce future visits if the park's night skies became less dark. The report estimates that even slight increases in light pollution—to levels comparable with nearby Alamosa or Breckenridge—could result in annual tourism revenue losses between approximately $176,000 and $295,000, with broader regional GDP impacts due to reduced visitor spending. Additionally, the loss in net consumer benefits, reflecting the overall value and happiness visitors derive from the park, could range from $708,000 to $4.5 million annually. These conservative estimates underscore the significant economic benefits of preserving dark skies and highlight the importance of continued efforts to mitigate light pollution for the sake of both the local economy and visitor experience.
