Along the eastern edge of the Rocky Mountains—where prairie lifts suddenly into jagged stone—Sun Tours offers something increasingly rare in modern travel: not merely a passage through scenery, but an entry into living memory. Based in the small rail town of East Glacier Park, at the threshold of the Blackfeet Indian Reservation, the company is independently owned and operated by Ed and Toni DesRosier, enrolled members of the Blackfeet and Assiniboine Sioux Tribes. As an authorized concessioner within Glacier National Park, Sun Tours centers its work on the deep history and enduring culture of a landscape the Blackfeet call the “Backbone of the World.”

Founded in 1992, Sun Tours grew from Ed DesRosier’s effort to partner with the park and restore a vital dimension of interpretation: the Blackfeet presence in their ancestral homeland. At the time, that perspective was largely absent from visitor narratives. The result is a touring experience that moves beyond scenic appreciation into cultural understanding. Routes trace the legendary Going-to-the-Sun Road, climbing from open grasslands into alpine passes, but it is the viewpoint—grounded, lived, and Indigenous—that defines the journey.

Guides, many of them lifelong residents of the reservation, interpret the terrain through Blackfeet history, spirituality and ecological knowledge. Their storytelling is layered and precise: accounts of the buffalo economy and seasonal migration, the uses of native plants for food and medicine and the complex, often contested history of the park itself. Landscape becomes text—read through memory, language and lived experience.

Visitors learn to recognize animal species and the rhythms that shape their movement across the land. They encounter common plants and roots not as field-guide entries, but as sources of nourishment, healing and tradition. Equally present are the stories, philosophies, and spiritual frameworks of the Blackfeet People—elements that transform a scenic drive into a deeper engagement with place.

Sun Tours offers a range of experiences, from half-day excursions to full-day and fully customized itineraries. Each is designed not simply to show the land, but to situate travelers within it—inviting a slower, more attentive way of seeing that lingers long after the road descends from the mountains.
