Colorado River Rafting Permits in Utah: By Section
The Colorado River through Utah offers dramatically different experiences by section — from flatwater floats through canyon country to serious Class IV–V whitewater. Permit requirements vary just as much. Understanding which sections require what permits, and how to get them, is the first step in planning any Colorado River trip.
Stillwater Canyon: Mineral Bottom to the Confluence (Green River)
Stillwater Canyon is the Green River corridor that runs from Mineral Bottom downstream roughly 52 miles to the confluence of the Green and Colorado Rivers inside Canyonlands National Park. It's a flatwater canyon float through increasingly dramatic red rock country — no rapids, towering walls, and genuine solitude. The Colorado-side equivalent above the confluence is Meander Canyon, launched from Potash near Moab.
Permit status: Overnight trips through Stillwater require a Canyonlands National Park backcountry permit specifying your campsites. Day trips on the river corridor currently do not require a launch permit, though this can change. The permit is applied for through recreation.gov and is first-come, not a lottery.
Planning note: Most groups float Stillwater (or Meander, on the Colorado side) and continue through Cataract Canyon, which is a separate Canyonlands permit. If you're doing a full trip from launch through Cataract to Lake Powell, you'll need the Cataract permit for the whitewater section regardless of which approach corridor you take.
Westwater Canyon: Rapid Whitewater Near the Utah-Colorado Border
Westwater Canyon sits just inside Utah on the Colorado River. It's roughly 17 miles of Class III–IV whitewater — one of the most accessible serious whitewater trips in the region. The canyon walls narrow to near-vertical black schist, and the river drops hard.
Permit requirement: BLM permit, managed by the Grand Junction Field Office (Colorado). Day use and overnight permits are both available. The system is first-come, first-served through recreation.gov — not a lottery.
Booking window: Permits open six months in advance. Spring weekends fill within days of opening. Weekday permits are more available but still worth booking early. Check recreation.gov starting exactly 180 days before your target date.
Fees: Launch fee plus a per-person day use fee. Current fees are listed at recreation.gov — confirm before booking as they update periodically.
Group size: Maximum 25 people. There's no minimum group size, but most trips run with at least two boats for safety redundancy on Class IV water.
Whitewater note: Westwater's Skull Rapid is Class IV at most flows. The Room of Doom — a deep eddy on river right below the rapid — is the major hazard; getting flushed into it can mean an extended retention. Skull is runnable on the standard line for crews with Class IV experience, and portage along the right shore is an option. Run it only with a trip leader who has prior experience on Westwater or comparable Class IV water.
Cataract Canyon: Big-Water Whitewater Below the Confluence
Cataract Canyon begins at the confluence of the Green and Colorado Rivers inside Canyonlands National Park and runs roughly 14 miles of whitewater followed by Narrow Canyon's slow run-out into Lake Powell. The Big Drop sequence is the crux: Class III–IV at moderate flows (5,000–15,000 cfs), solid Class IV through high water, and Class V only above ~50,000 cfs — flood-stage spring runoff that occurs in rare big-snow years.
Permit requirement: Canyonlands National Park backcountry permit, applied through recreation.gov. This is an NPS permit, not BLM. Both a per-permit reservation fee and a per-person per-night fee apply; confirm current amounts at recreation.gov at time of booking.
Booking: No lottery. Canyonlands releases Cataract permits seasonally on a fixed schedule — typically four months ahead of each season. The spring window fills within hours of opening. Watch recreation.gov for the next release date and book the moment it opens.
What the permit covers: The permit specifies your launch date, group size, and duration. You'll list your campsites when applying, choosing from designated sites on the river corridor map. Rangers may check your permit at put-in (near the Confluence) or on the river.
Trip leader requirements: NPS requires a designated trip leader who accepts responsibility for compliance. No specific certification is required, but the park expects trip leaders to have relevant whitewater experience for the Class IV (and at flood stage, Class V) conditions possible during peak runoff.
Applying and Cancellation Strategy
All three sections use recreation.gov for permit applications. Create your account before you need it — group member information, payment methods, and vehicle details can be saved in advance, which speeds up the booking process when a permit drops at midnight.
For first-come permits: Set an alert for exactly 180 days before your target date. Be at your computer at midnight Mountain Time. Have your group roster and credit card ready.
For cancellations: After a permit window opens, groups frequently cancel. The reason varies — life changes, conditions look bad, the group falls apart. Checking recreation.gov in the weeks before your target date, especially in the 60–30 day window, regularly turns up openings. The cancellation list on recreation.gov is visible in real time — refresh and check.
If you can't get a private permit: Commercial outfitters hold separate permit allocations for all three sections. A commercial trip costs more but guarantees access. Reputable outfitters operating Westwater and Cataract include Holiday River Expeditions, OARS, and Mild to Wild. Book commercial trips 3–6 months out for peak season.
