Class III-IVGlenwood Canyon, CO
Colorado River — Glenwood Canyon

Too LowAbout this run
Glenwood Canyon is one of America's great natural wonders — and it has the whitewater to match. At current flows, the canyon delivers sustained Class III-IV wave trains and powerful hydraulics that flip unprepared boaters regularly. The canyon walls rise 1,200 feet of Precambrian granite, and I-70 runs the full length above — easy shuttle but no escaping the grandeur. Current high water creates pushy, technical lines throughout.
Known Hazards
- Powerful hydraulics at multiple rapids — avoid far river left
- High water creates strainers on river-left at numerous bends
- I-70 debris and runoff after heavy rain
- Cold water year-round from deep canyon shade
