Gates of Lodore: The Complete Guide (Permits, Rapids, Camping & Best Time to Go)

Written by

Rafting through the Gates of Lodore on the Green River

Short answer: The Gates of Lodore is a 44-mile stretch of the Green River through Dinosaur National Monument, named by John Wesley Powell’s 1869 expedition. It holds three named Class III-IV rapids, requires a hard-to-win private permit for noncommercial boaters, and runs a season from roughly June through September. Guided trips skip the permit lottery entirely.

Key Takeaways

  • The canyon runs 44 miles from the Gates of Lodore put-in down to the Split Mountain take-out.
  • Three named rapids define the trip: Disaster Falls, Triplet Falls, and Hell’s Half Mile, all Class III-IV.
  • Private boaters compete for one of just 300 high-use season permits shared with the Yampa River, against thousands of applicants.
  • Guided trips run under an outfitter’s concession permit, no lottery required.
  • The 4-day trip continues past Split Mountain through Echo Park, where the Yampa River joins the Green.

A Little History

The Green River flows south out of Browns Park into Dinosaur National Monument, cutting through the Uinta Mountains, the largest east-west mountain range in the lower 48. John Wesley Powell’s 1869 expedition named this stretch the Gates of Lodore, and three rapids impressed him enough to name them individually: Disaster Falls, Triplet Falls, and Hell’s Half Mile.

The canyon runs differently today than it did for Powell, mostly because of the Flaming Gorge Dam upstream, which regulates flow and extends the rafting season well beyond what spring runoff alone would allow.

The Permit Lottery, and Why Most People Skip It

Boating inside Dinosaur National Monument requires a permit. For private, noncommercial boaters, that means entering a lottery through Recreation.gov during the December 1 to January 31 application window. Only 300 high-use season permits are issued total, shared between the Green River (Gates of Lodore) and the Yampa River combined, against thousands of applications each year.

Guided trips work differently. Licensed outfitters hold their own NPS concession permit, and guests traveling with a guided trip need no private permit at all. You pick a date and you’re going, no lottery, no waiting on an email in February.

The Rapids

Rapid Class Notes
Disaster Falls III-IV The first major named rapid, scouted by guides before running
Triplet Falls III-IV A series of drops requiring careful line selection
Hell’s Half Mile III-IV The canyon’s signature rapid, adjusted for water levels

Class ratings shift with seasonal water levels. Our guides scout every named rapid before running it and adjust the line based on current flows and group experience.

Camping and Logistics

Multi-day trips through the Gates of Lodore start at 7:00 AM, and we recommend meeting the group in Vernal the evening before departure for orientation and dry bag packing. Camps are set up on sandy river beaches inside the canyon. All camp meals are guide-prepared, and tents, sleeping pads, PFDs, and helmets are provided. The Split Mountain take-out has reservable group campsites with seasonal flush toilets and vault toilets.

Best Time to Go

The season generally runs from late spring through early fall, with water levels and rapid intensity shifting throughout. Early-season trips tend to see higher, faster water, while late-summer trips run mellower. Talk with us about which window fits the experience you’re looking for.

Trip Options

The 3-day trip covers the core Gates of Lodore run. The 4-day trip continues past Split Mountain and through Echo Park, where the free-flowing Yampa River joins the Green beneath Steamboat Rock, a confluence you only get by continuing downstream.

Heroes and Outlaws

Heroes, Outlaws or Both 

By: Kassie Robbins

The Old West, in particular the eastern country of the three closely bordered states Wyoming, Colorado and Utah have a huge place in my heart. I grew up visiting these regions as a young impressionable girl. 

My mother was born and raised in the small rural town of Vernal, UT. This little town is where the love of white water river rafting on the Green River, hiking the canyons, and exploring Dinosaur National Monument came into my life. This was our second home at times of our lives as my father often traveled out of the country months at a time.  

My mother would bring us here to stay with our Grandmother, Alta Winward. Grandma Alta would unleash her love for the early history of the Uintah Basin with wonderful stories about the region and its colorful characters. 

She spent much of the time educating and sharing stories focused on the sisters, Josie and Anna Basset, as well as Butch Cassidy and the Wild Bunch. I have traversed a lot of  this rugged country of those western Heroes/Outlaws since I was a little messy haired tomboy wanting to climb every rock and swim in the Green River every chance I got. 

I personally looked up to the outlaws of that time and they are Heroes in my book. They lived in the rough country and survived off the land. These two sisters were born to Herb and Elizabeth Bassett. Josie was four years old when they relocated to Brown’s Hole from Hot Springs, Arkansas.  Anna was born four years later on May 12, 1878.  

Brown’s Hole now referred to as Brown’s Park was rugged and remote outlaw rough country.  

These girls grew up taking care of things around the Bassett Ranch. They learned how to handle horses, rope and wrangle cattle, and shooting to name a few. One day in 1886, they decided to go to a local nearby horse and cattle rustler, Charlie Crouse’s ranch. Charlie was holding horse races and the girls were curious about horse racing. Their young minds wanted to watch the horses and learn more. Both of these young ladies grew up to be very competent horse and cattle ranchers.  

12-year old Josie and 8-year old Ann were captivated for the first time by George Leroy Parker, later referred to with his alias as Butch Cassidy. He gallantly rode Charlie’s gelding in a race.  Though the girls were impressed with the gelding, the fetching blonde-haired young man caught their tween eyes.  

Josie recalled,

“I thought he was the most dashing and handsome man I had ever seen.  I was such a young thing, and giddy as most teenagers are.  I looked upon Butch as my knight in shining armor. He was more interested in his horse than he was of me, and I remember being very put out by that.  I went home after being snubbed by him and stamped my foot on the floor in frustration.”

Over time Butch Cassidy was often offered sheltered, resupplied as well as worked off and on at the Bassett Ranch. This country was great for hiding out since he and the Wild Bunch could easily evade the law crossing state lines.  Butch and Josie had a short-lived romance but between his wild ways always coming and going, her going to Catholic School in Salt Lake, it ended. Josie’s father denied that Butch was ever in such rubbish as robbing banks because he was a kind and hard worker.  

These folks are the heart of the west full of love and life and adventure. There was struggle but these were full of grit and they continued to wrestle the tough life of living in the rugged country of Brown’s park. Undeniably there is so much rich history to be had about them.

These historical heroes left an impression on me as a young girl and some of these trails of which they walked are some of my favorite memories with my Grandma.  

You can explore the vast history of this amazing area by enjoying a float down the Green River with Dinosaur River Expeditions.
