Boulder Mail Trail

Trip Description

The Grand Staircase-Escalante National Monument is an outdoor enthusiast’s dream featuring endless sandstone canyons, waterfalls, natural arches, hanging gardens and ancient Native American ruins. The Boulder Mail Trail traverses the Death Hollow Wilderness, a one-of-a-kind slickrock playground featuring incredible scenery and expansive views. This is an overland route that was originally used in the early 1900s to deliver U.S. mail between the remote towns of Escalante and Boulder. Now seldom visited, this wild and unique wilderness offers outstanding opportunities for quiet and solitude. You will hike across great expanses of Navajo sandstone studded with ponderosa and pinyon pines, cross several canyons including Death Hollow and Sand Creek and camp in world-class scenery. After crossing the Death Hollow Wilderness, the hike continues with a 14-mile trek through a stunning section of the Escalante River gorge complete with natural arches, cliff dwellings and ancient rock art. This outstanding Utah backpacking tour is a perfect trip for those looking for an off-the-beaten-path backpacking adventure in a truly magical landscape.

Trip Itinerary

Day 1:

Depart St. George early for your scenic drive through southern Utah. Upon arriving in the Escalante area, we will finalize our packing and meet our shuttle driver who will transport us to our starting point near the town of Boulder. After final preparations, we will begin our hike to Death Hollow. The stunted pine forests quickly give way to a seemingly endless slickrock wilderness ahead as we begin our short descent to the bed of Sand Creek. When then continue across more open slickrock to a spectacular overlook above Death Hollow. Watch your footing as we make the exciting descent to the floor of the canyon. We will make camp beneath the towering pines along the banks of Death Hollow’s perennial stream.
Drive Time: 4 hours
Distance & Elevation: 6 miles, 700 foot descent
Breakfast, Lunch, Dinner

Day 2:

Today’s hike will be highlighted by Mamie Natural Bridge and the epic views across Antone Flats. After the challenging climb out of Death Hollow, you will be treated to more incredible views while we traverse the slickrock on our way to Mamie Canyon. We will drop our backpacks and make the short walk down to Mamie Natural Bridge for lunch. Next, we will return to our backpacks and make our way towards Antone Flats for our second night’s camp. Enjoy the beautiful sunset over the Death Hollow Wilderness as your guides prepares a delicious dinner.

After a tasty breakfast, we pack up camp and head out across the rest of Antone Flats and up to a high ridge overlooking Pine Creek and the town of Escalante. Back to west, you are rewarded with views across the entire Death Hollow Wilderness and Boulder Mountain to the north. We begin the scenic descent towards Pine Creek and its confluence with the Escalante River, where we will head east into the sandstone gorge below. Watch as the walls grow higher with each sinuous bend in the canyon. We will camp this evening beneath a giant, natural sandstone alcove.
Distance & Elevation: 8 miles, 700 descent

Day 4:

Enjoy your morning coffee as the sunrise glows golden upon the towering cliffs around you. Another breakfast and it’s on downstream. The Escalante River (more like a small stream) creates a lush canyon oasis, complete with cottonwood trees and swimming holes. As we continue down the canyon, we’ll see ancient Native American cliff dwellings, rock art, and beautiful streaks of desert varnish on the canyon walls. As we reach the confluence with the mouth of Death Hollow, we will drop our packs and enjoy a side hike into its lower reaches. Then it’s on to our final night’s camp near a natural sandstone arch on the canyon rim.
Distance & Elevation: 8 to 10 miles, 200 descent
Breakfast, Lunch, Dinner

Day 5:

Our final day of hiking will take us the last few miles to our endpoint near Calf Creek. Enjoy views from beneath Escalante Natural Bridge and a stop at the Hundred Hand Panel, a remarkable rock art site. After a rewarding lunch back at the trailhead and a quick pit stop in the town of Escalante, we’ll make the drive back to St. George, arriving by 5pm.
Distance & Elevation: 4 miles, minimal descent
Breakfast, Lunch

Guest Testimonials

“This was our third trip with Four Seasons (previously did Rim to Rim and Yosemite/Half Dome) and each one has been great. Most recently experienced a fabulous 5 day trek in Utah on the Boulder Mail Trail. Our guide, Bob, was experienced, friendly and flexible. Equipment provided was first rate and the food, transportation and logistics all went according to plan. Highly recommend this trip with Four Seasons if you want a challenging and fun adventure with breathtaking scenery and solitude.” – Drew P.

“Amazing location, amazing group, amazing guide. The whole experience was beyond expectations. We were pleasantly surprised that our guide was Jeremy, whom we had hiked the Grand Canyon Rim to Rim hike back in 2019. Jeremy goes out of his way to take good care of every one of his customers. This time it was the Boulder Mail Trail in Utah. What a beautiful state! Backcountry hiking at its best. Mostly we had the place to ourselves. Definitely glad I took their advice and trained for this hike as this was no beginner hike.” – Mark L.

“Boulder Mail Trail is my third trip with Four Season Guides, and they just keep getting better. Their ninja logistics skills rival world class militaries. Get in shape, get to the start, and they handle everything else. Great gear, great routes that are diverse and well timed for weather and nature, highly experienced/skilled/knowledgable/friendly guides, and not your standard freeze dried camp meals. I can’t wait for my next trip!” – Mary C.

“I just completed my third backpacking trip with Four Seasons Guides, this time the Boulder Mail Trail in Grand Staircase-Escalante National Monument in Utah after two Grand Canyon hikes. Scott, our guide, proved he knows this region at least as well as the Grand Canyon, which we hiked with him last year. Scott has the technical and social skills to make any trip thoroughly enjoyable. When we needed to adapt the itinerary slightly to ensure availability of water, Scott was clear and forthright about our choices. (And we ended up seeing more of the gorgeous Escalante River canyon than we might have otherwise.) He is interested and conversant in a wide range of topics and makes his guests feel right at home. In advance of the trip, Dave is always available to offer any help or guidance needed. This is a first-rate company that intentionally stays small and focused on the Southwest to provide the best possible service. Its guides are deeply experienced, knowledgable and dedicated to running successful trips. Four Seasons is a top-notch outfit.” – Larry F.

“Our third backpacking adventure with Four Seasons Guides was another “Experience of a Lifetime.” The spectacular Escalante region challenged us physically and rewarded us mentally and spiritually. Our experienced, organized, calm and skillful guide, Scott, engaged and motivated us with his enthusiasm, knowledge, and reverence for the land and its ancient inhabitants. He carried a massive pack of untold weight so the rest of us could manage the steep ascents and descents with our own big packs. He fed us well, kept us hydrated with purified water from fresh sources, and challenged us to be stewards of this precious natural wilderness. As always, company owner Dave was available for months in advance to respond to our questions and concerns. This is a beautifully-run company which makes makes every guest feel welcome and part of the family. We will continue to travel with them again and again.” – Robert K.
