Estes Park Guide Companies: Longs Peak Permits & Pricing
Guide Companies
Colorado Mountain School (CMS) is the primary guide operator for Longs Peak and one of the leading mountain guide companies in the American West. Based directly in Estes Park, CMS offers guided ascents of the Keyhole Route as well as instruction courses covering rock climbing fundamentals, high-altitude movement, and more technical alpine routes including approaches to the Diamond.
- Guided Keyhole Route ascents — private and small group formats
- Rock climbing and alpine instruction courses in RMNP
- Technical route guiding including Diamond East Face for qualified parties
- AMGA-certified guides; NPS Commercial Use Authorization holder
- Gear rental available through CMS for select items
Kent Mountain Adventure Center (KMAC) is an Estes Park–based guide service offering guided ascents of Longs Peak and other Colorado 14er objectives. KMAC has a strong local reputation and operates specifically within RMNP under a Commercial Use Authorization. A solid alternative or complement to CMS for parties seeking smaller or more personalized guided experiences.
- Guided Longs Peak Keyhole Route ascents
- Colorado 14er guiding including other Front Range objectives
- Private guide formats available for small parties
- NPS CUA holder for Rocky Mountain National Park
Any guide operating commercially on Longs Peak within Rocky Mountain National Park is required to hold a current Commercial Use Authorization from the NPS. Operating without a CUA is illegal. Before booking a guided Longs Peak trip, confirm that the operator holds a valid RMNP CUA — reputable operators list this clearly on their websites. If a guide cannot confirm their CUA status, look elsewhere.
What Guided Gets You on Longs Peak

| Weather judgment | Experienced guide applies go/no-go discipline with real-time judgment | Self-reliant; must read weather independently and be willing to turn back |
| Emergency response | Guide trained in wilderness first aid; knows evacuation procedures | Party carries first aid skills collectively; must self-rescue or call for help |
| Pacing & acclimatization | Guide manages pace and monitors altitude symptoms throughout the day | Self-managed; common cause of AMS incidents is poor self-pacing |

| Flexibility | Set itinerary and schedule with operator | Full flexibility on timing, pace, and route decisions |
