Trace a historic pioneer trail into one of the most spectaular canyons in Grand Staircase-Escalante

The Escalante Canyon Country is chock full of incredible canyon and slickrock adventures, and The Boulder Mail Trail traces a historic route into one of the greatest. Death Hollow Canyon, Slickrock Saddle, and The Escalante River are wondrous, scenic, and remote places to explore and hike, and we will do just that on The Boulder Mail Trail Backpacking tour.

This is located right in the heart of southern Utah’s canyon country, and the Boulder Mail Trail is precisely what its name implies; an historic pioneer mail route that connected the burgeoning towns of Boulder and Escalante.

Our adventurous tour here delves into some of the grandest scenes in all of Utah and the Grand Staircase, so come along!



Hikers should have the ability to walk up noticeable elevation change and over uneven ground and surface for up to 9 miles per day and carrying a small pack of gear. Many routes and trails don’t have a shortcut or turn-around option. The hiking party moves at a gentle but steady walking pace with breaks.


A real back-packing trip, comfort is what you carry with you. There are no showers or electricity on the trail and restrooms are primitive. Backpackers can expect to sleep on a sleeping pad outdoors or in a small tent. Food consists of single-entrée meals, some food are freeze-dried or dehyrdrated with a few fresh food selections. Meals are prepared by your guide and served “group-style” out of pots and usually eaten out of personal meal-kits while sitting on the ground.2


While hikers will pass through areas popular with tourists, they will spend most of the time in areas specially selected to be off the beaten path. There will be practically no wait time or crowds anywhere past the trail-heads. Overnighting is private and remote.

The Boulder Mail Trail Backpacking tour will depart St. George, Utah, traversing the highway through outstanding slick rock country.  The trail begins near the town of Boulder and snakes its way into a wonderland of gnarled sandstone.  We cross Sand Creek before coming to a most impressive landscape, Death Hollow.  We will make camp here, and dream of the breathtaking descent into this wild canyon.

Time in the car: 2.5 hours
Elevation & Distance: 6 miles, 300 foot ascent
Food: Light Breakfast, Lunch, Dinner


After some warm coffee and a hearty breakfast, we begin the fabulous descent into Death Hollow.  The canyon looks as though it might swallow us, as it did the many mules that gave it the name Death Hollow!  Upon reaching the bottom we find a gurgling stream, cottonwoods, and ponderosa that are the refuge of myriad wildlife.  We are heading for Mamie Creek this evening, still tracing the old pioneer mail route.  Another outstanding camp awaits us this evening. 

Elevation & Distance: 6 miles, 1400 foot descent
Food: Breakfast, Lunch, Dinner


Today we head downstream to explore Mamie Creek, and one of the most unique natural bridges in Grand Staircase-Escalante.  Mamie Creek Natural Bridge creates an almost grotto-like feel, and we’ll spend the day finding the hidden pools and waterfalls of the creek.  Sweeping views into Death Hollow are the backdrop for this amazing day of exploration.  After returning to camp, expect wild sunsets across the slickrock and an evening of pure wild.

Elevation & Distance: 9 miles, 350 foot descent
Food: Breakfast, Lunch, Dinner


Our adventure this morning is across Antone Flats.  Drink in the panoramas of canyon, cliff, forest, and mountain as we nearly dance across the multi-hued slickrock.  We’ll make another descent of a high plateau into the scenic Escalante River Valley, and imagine ourselves as the hardiest of mailmen making our adventurous deliveries!  We’ll pile into the shuttle, and celebrate like geologist, with a cold beverage at a local watering hole.

Elevation & Distance: 6 miles, 600 foot descent
Food: Breakfast, Lunch
Time in the car: 1 hour

DAY 5 or 6 Options

The 5- and 6-day custom options give us some flexibility.  The 5-day option takes us back down into Death Hollow and out to the Escalante Canyon, the a signature Utah landscape.  The 6-day option allows us to have a bit of a rest day along Mamie Creek before making our break for Escalante.  No matter the itinerary you choose, the extra days allow for stupendous exploration and adventure!

Elevation & Distance: 5 miles, minimal descent
Food: Breakfast, Lunch, Dinner
Time in the car: 2 hours
