The guides here clearly make all the difference. Reviewers consistently praise staff by name—Benjamin, Caroline, Stella, Pat, Roy, and many others—for their knowledge, professionalism, and genuine care. Whether it's someone helping a 75-year-old hiker manage the heat, bringing hot coffee to guests on a chilly glacier, or extending a tour when timing didn't match expectations, the personal attention stands out. The operation offers everything from Kennecott Mill tours to multi-day wilderness adventures, glacier hikes, ice cave explorations, and rafting trips. The experiences range from accessible half-day outings to seriously challenging multi-day treks that reviewers describe as "not for the faint of heart." Guests appreciate that guides adapt to their group's needs and abilities while keeping safety front and center. The mill tours get special mention for being both informative and entertaining, with access to restricted areas you can't see on your own. People leave with what one reviewer perfectly called "core memories"—the kind of Alaskan adventure that feels both thrilling and remarkably well-supported.
We took a private ice cave tour with St. Elias Alpine Guides, the guide was professional. The ice cave was gorgeous. Please choose them if you want to get some adventure there!
