Cataract Canyon Rafting: A Complete Planning Guide

Cataract Canyon is the wildest stretch of the Colorado River in Utah. Tucked between Canyonlands National Park and Lake Powell, it holds some of the most demanding whitewater in the American Southwest — including the Big Drop sequence, a trio of Class IV–V rapids that have flipped rafts and humbled experienced paddlers for generations. This guide covers everything you need to plan a self-guided or guided trip; for the deeper field-guide treatment, see Rafting Cataract Canyon.

The Route

The standard Cataract Canyon trip puts in at Moab, Utah, at the Potash boat launch or Mineral Bottom on the Green River, and takes out at Hite Marina on Lake Powell — roughly 100 miles total.

Moab to the Confluence: About 65 miles of flatwater through Meander and Stillwater Canyons. The walls are red sandstone and the current is slow. This section takes 2–3 days and is often the most underestimated part of the trip. Bring more water and sunscreen than you think you need.

The Confluence: The Green and Colorado Rivers meet here in a wide, sandy bend inside Canyonlands National Park. It's worth stopping. In summer and fall, the dam-regulated Green often runs visibly clearer than the silt-rich Colorado, and the line between the two waters is visible downstream until they fully mix. In spring runoff that distinction disappears — the Yampa and other Green-side tributaries load the Green with sediment, and both rivers can run heavy together. Either way, downstream of the Confluence the combined river is what Webb describes as "usually muddy and changes temperature seasonally," which is the working condition for most of Cataract.

Cataract Canyon: Roughly 14 miles, starting just below the Confluence. From Brown Betty (Rapid 1, just below Spanish Bottom) to Imperial Canyon Rapid (Rapid 27, partially submerged by Lake Powell at the historical reservoir level), the canyon holds 29 numbered rapids in Webb's canonical Table 8-1 — Rapids 1–27 plus Lower Rapid 5 and Lower Rapid 23. Most are Class III; only a handful carry proper names. Notable named rapids: Brown Betty (Rapid 1), Capsize Rapid / "Hell to Pay" (Rapid 15), Button Hole (Rapid 18), Ben Hurt (Rapid 20), the Big Drops (Rapids 21–23, with Satan's Gut as the left-side pourover feature inside Big Drop 3), and Imperial. Mile Long Rapid is the collective name for Rapids 13–19, a continuous reach from Range Canyon's debris fan to the island at Rapid 20; the high-water section through Rapids 16–19 is called the "South Seas" for its irregular wave train. The Big Drop sequence — three rapids in quick succession near mile 10 of the whitewater corridor — is the crux of the trip. Big Drop 3 is Class IV through most of the runnable range; flood-stage flows above ~50,000 cfs push it into Class V territory. Below Imperial, Webb numbered Rapid 28 (Waterhole Canyon outwash) and others that have been submerged by Lake Powell since it first filled; as the reservoir drops, those reemerged rapids are returning to the canyon and adding to the modern count.

Hite Marina to Lake Powell: After the last rapid, the river slows as it backs into Lake Powell. Depending on the reservoir level, you may motor or paddle several miles across flat water to the takeout at Hite.

Permits

All overnight trips in Cataract Canyon require a permit. Permits are issued through recreation.gov under the Canyonlands National Park permit system.

• Lottery period: Applications typically open in January for peak spring permits. Check recreation.gov for current dates.
• Cost: Permit fees are charged per person per night, plus a non-refundable application fee.
• Group size: Maximum 25 people per permit.
• What the permit covers: The river corridor through Canyonlands. Your permit specifies your launch date and group size.

If you missed the seasonal release, some permits become available as walk-up or cancellations closer to the season. Check recreation.gov frequently in March and April.

Flow Levels and Difficulty

Cataract Canyon's character shifts dramatically with water volume. The right gauge depends on which side of the Confluence you're launching from: the Potash gauge (09185600) reads the Colorado at the Potash boat ramp, and the Mineral Bottom gauge (09328920) reads the Green at Mineral Bottom. Either is the launch-day flow you'll actually run; sum the two for the combined flow that reaches the Big Drops. Below the Big Drops, the Gypsum Canyon gauge (09328960) reads what's flowing through the reservoir-influenced lower miles — useful for take-out conditions at Hite or North Wash and for tracking the canyon's slow re-emergence as Lake Powell drops.

• Below 5,000 cfs: Low water. Many rapids are rocky and technical. Big Drop becomes more of a boulder maze than a big-water rapid. Slower flatwater sections feel longer.
• 5,000–15,000 cfs: Classic moderate flows. Solid Class III–IV throughout. Big Drop 1, 2, and 3 are challenging but manageable for experienced crews. The best window for self-guided trips.
• 15,000–35,000 cfs: High water, big-water Class IV. Hydraulics intensify and pool recovery shrinks. Big Drop 3 stays Class IV but with serious consequence. Scout every major rapid. The window for experienced big-water crews.
• 35,000–50,000 cfs: Serious big water. The Big Drops are heavily consequential Class IV pushing toward V. Beaches at the larger camps flood. Self-guided trips at this level demand expedition-level skill.
• Above 50,000 cfs: Flood-stage Class V. Rare — only happens in big-snow runoff years. Many groups portage Big Drop 3 along the right shore. Not recommended for self-guided groups without expert big-water experience.

Check current flows at waterdata.usgs.gov before your trip and revisit in the days before launch.

The Big Drop Sequence

Big Drop 1, 2, and 3 are the defining moments of any Cataract Canyon trip. They come in sequence over roughly half a mile — you'll hit 1, eddy out, hit 2, eddy out again, then face 3.

Big Drop 1 is a straightforward Class III–IV entry. A large hole on river right is the main hazard. Entry line: river left, threading between the center tongue and the right hole.

Big Drop 2 (Little Niagara) is a wide drop with a powerful hydraulic across much of the river at high flows. Scout from river left. At moderate flows, a clean line runs center-left.

Big Drop 3 (with Satan's Gut as the left-side pourover feature) is the monster — a long rapid with a chaotic mid-section and a large keeper hole at the bottom right. The standard run threads right of center at most runnable flows. At flood-stage flows above ~50,000 cfs, most groups portage or line boats around the right shore. Scout carefully — the line at moderate flows is climbable for experienced crews, but it's not forgiving.

Take time to scout all three. They're too close together and too consequential to run blind.

Guided vs. Self-Guided

Self-guided: You need solid multi-day river experience, good swiftwater rescue skills, and a properly rigged raft (minimum 14-foot oar rig with D-rings, dry boxes, and a bail pump). The permit, shuttle logistics, and safety decisions are entirely yours. Budget $800–1,500 per person for gear rental, shuttle, and permit fees if you're renting rather than owning equipment.

Guided: Licensed outfitters offer full-service Cataract Canyon trips at $1,500–2,500 per person for 5–7 days. They handle permits, shuttle, all camping and cooking gear, and bring trained river guides. For less experienced paddlers, a guided trip is the right call — the Big Drop sequence at high water has a real consequence for flipped boats.

If you're on the fence, book a guided trip for your first run. Come back self-guided once you know the canyon.

Campsite Planning

Cataract Canyon campsites are sandy beaches. Most are well-established and shown on NPS maps. Highlights:

• Spanish Bottom — Large, flat beach just above the rapids. Good first camp after the Confluence.
• Cataract Camp — Used often after the first day in the canyon.
• Below Big Drop 3 — Several small beaches used as post-crux celebration camps.

All human waste must be packed out. NPS requires a groover on every trip. Fires must be in a fire pan; no fires directly on sand or vegetation. Use a fire-blanket, they are cheap and they make for easy clean-up, otherwise bring a shovel. Leaving No Trace is something to take pride in. NPS requires the fire pan and to take out ash on every trip.
