Green River Utah Float Trip: A Complete Planning Guide

The Green River in Utah runs through some of the quietest canyon country in the American Southwest. Depending on which section you float, you'll spend days in Labyrinth Canyon's red-walled solitude or put in above Cataract Canyon's whitewater. This guide covers planning a flatwater float through Labyrinth Canyon — the most accessible multi-day Green River trip.

Sections of the Green River in Utah

The Green River offers dramatically different experiences depending on where you put in and take out.

Labyrinth Canyon — Green River State Park to Mineral Bottom, roughly 68 miles. Flatwater. No whitewater. This is the classic multi-day float: calm water, towering canyon walls, sandy campsites, and almost no other people mid-week. Permits required for overnight trips.

Stillwater Canyon — Mineral Bottom to the Confluence with the Colorado, roughly 52 miles. Flatwater inside Canyonlands National Park. The continuation corridor for crews running through to Cataract.

Desolation/Gray Canyon — Sand Wash to the Swaseys ramp, 84 miles. (Carrying on to the town of Green River adds roughly another twelve.) More remote, some Class II–III rapids. Requires a lottery permit, administered by the BLM Price Field Office.

Where the Green meets bigger water

Beyond the Green's own corridors, two adjacent options come up often in Utah trip planning:

  • Cataract Canyon sits below the Confluence on the Colorado mainstem, roughly 14 miles of Class III–IV whitewater (Class V only at flood-stage flows above ~50,000 cfs). Reached via Stillwater on a Green-side launch from Mineral Bottom.
  • Ruby-Horsethief Canyon is a Colorado River flatwater section near Fruita, sometimes combined with Westwater for a taste of whitewater. Listed here for completeness — it's not a Green River trip.

Labyrinth Canyon: what to expect

Labyrinth Canyon is named honestly. The river loops through increasingly tight meanders, the walls rise to 1,000 feet, and the only sounds are water, wind, and the occasional raven. There are no developed amenities on the river — no toilets, no fresh water, no cell service.

The current does most of the work. Expect to cover 10–15 miles per day without effort. A four-day trip is comfortable at a relaxed pace. Five or six days gives you time to explore side canyons.

Water: The river water is silty and must be filtered. Bring a quality filter — Sawyer Squeeze or a gravity filter for groups. You'll use river water for everything: drinking, cooking, dishes.

Sanitation: Groover required. BLM mandates carry-out waste systems on all overnight trips. Plan for one groover per group.

Shade: There isn't much. Canyon walls provide morning and evening shadow, but midday sun hits the river directly. A shade tarp rigged over your raft is worth the weight.

Permits

Overnight trips through Labyrinth Canyon require a river permit from the BLM Moab Field Office. It is free and self-issued — not a recreation.gov reservation, not a lottery, and not a quota. Download the permit form from the BLM, sign it, carry a copy on the river, and email a completed copy to the Moab Field Office before you launch. There is no application window to race and no results date to wait for.

The permit covers your group, your put-in date, and your number of nights. Group size is capped at 25.

Permit fee: None for the self-issued overnight permit. Confirm the current form, any fee, and day-use rules on the BLM's Labyrinth Canyon page before you launch.

Campsites: Not reserved. The BLM's Labyrinth Canyon river map shows campsite locations — download it along with the permit form before you lose cell service.

Shuttle logistics

Labyrinth Canyon is a point-to-point float — you put in at Green River State Park and take out at Mineral Bottom. Shuttle options:

  • Commercial shuttles: Several companies in Green River, UT will drive your vehicle to Mineral Bottom and drop you at put-in. Expect to pay $100–$200 depending on vehicle size and group.
  • Two-vehicle shuttle: Leave one vehicle at Mineral Bottom, drive to put-in in the second. Mineral Bottom road is well-maintained gravel — passenger cars can make it in dry conditions.
  • Bike shuttle: Some groups shuttle bikes to Mineral Bottom and ride out on the White Rim Road. The climb out from the river is significant — plan a half-day for the ride.

Water levels and flow

The Green River at Green River, Utah (USGS gauge 09315000) is the relevant gauge. Typical spring flows run 3,000–8,000 CFS. The river is floatable at very low flows (under 1,000 CFS) but slower and shallower.

Check waterdata.usgs.gov before your trip. Very high flows (above 15,000 CFS) make camping difficult — beaches disappear under water.

Gear essentials

For a flatwater desert float, your gear priorities differ from a whitewater trip:

  • Sun protection: Wide-brim hat, long-sleeve sun shirt, SPF 50+. The river amplifies heat.
  • Shelter: A shade tarp is more useful than extra tent weight.
  • Water filtration: Sawyer Squeeze or Katadyn BeFree for individuals; gravity filter for groups.
  • Dry bags: Personal gear in a 65L dry bag. Electronics and sleep gear double-bagged.
  • Sandals: River sandals with secure straps. Chacos or Tevas — avoid flip-flops.
  • Groover: Rent from an outfitter in Green River if you don't own one.

Campsites

The campsites marked on the BLM's Labyrinth Canyon map are all sandy beaches. Most have good shade from tamarisk or canyon walls in the evening. Popular sites:

  • Trin-Alcove Bend — One of the most scenic bends in the canyon, around mile 20.
  • Fort Bottom — Historic structure, worth the short hike up from the river.
  • Mineral Bottom — The takeout, with a BLM toilet and parking area.

Leave No Trace rules apply. Pack out everything. Do not build fires except in established rings.

Frequently asked questions

Do you need a permit for a Green River float trip in Utah?
It depends on the section. Overnight trips in Labyrinth Canyon require a free, self-issued BLM river permit from the Moab Field Office — download the form, sign it, carry a copy, and email a completed copy before you launch. It is not a recreation.gov reservation and not a lottery. The Ruby-Horsethief section is managed by BLM and also requires a permit. Day-use rules differ by section; overnight trips always require a permit.
What is the best time of year to float the Green River in Utah?
April through June is peak season — flows are reliable, temperatures are mild, and the canyon is green from spring rains. Fall (September–October) is quieter and cooler. Avoid summer midday heat in July and August unless you're prepared for triple-digit temperatures.
How many days does a Green River float trip take?
Labyrinth Canyon from Green River State Park to Mineral Bottom is typically 4–6 days at a relaxed pace. Ruby-Horsethief to Westwater is a half-day to full-day float. The Desolation/Gray Canyon section is 7–9 days.
What kind of boat do you need for the Green River?
Labyrinth Canyon is flatwater — canoes, kayaks, and rafts all work. No whitewater experience required. If you're continuing through Stillwater Canyon and into Cataract, you'll need a raft (or hardshell kayak) and a crew rated for Class III–IV — Cataract pushes into Class V only at flood-stage flows above ~50,000 cfs.
Can you camp anywhere on the Green River in Utah?
In Labyrinth Canyon, the BLM publishes a river map showing campsite locations, but the self-issue permit does not assign you a site — you pick as you go. In Ruby-Horsethief, camping is at established sites along the river. Check current BLM regulations before your trip, as rules change seasonally.
