Boulder Mail Trail


  •   Guides Choice backpacking trip
  •   Historic mail and supplies route
  •   Breathtaking canyon country landscapes
  •   Vast high desert views of Southern Utah
  •   3 distinct, stunning canyons
  •   Natural bridges and slickrock
  •   Cascades and desert oases
  •   The enchanting Escalante River
  •   Amazing night skies


The Boulder Mail Trail offers the opportunity to traverse Utah’s finest canyon country. This wilderness route is a rewarding adventure across a sea of slickrock formations, high plateau Ponderosa Forests and deep shady canyons with spring-fed creeks. It is a trip not to be missed and will be one you'll think back on again and again!

The Grand Staircase - Escalante National Monument is one of the most beautiful regions in Utah with it’s unique, undulating terrain and brilliant sandstone features. The route takes us across a stunning plateau that was historically used to transport mail and supplies between the towns of Boulder and Escalante. It crosses three major canyon systems and many smaller tributaries that feed into Death Hollow and eventually into the Escalante River.

Each canyon along the Boulder Mail trail has a unique and interesting character. Sand Creek is a high elevation drainage that seems lost in time with the massive feature of Slickrock Saddle rising high above in the distance. Death Hollow is a deep, wet canyon full of water and a lush riparian environment. Mamie Creek is a large drainage of Navajo Sandstone featuring one of the most interesting Natural Bridges in the state of Utah as well as deep water pockets and excellent swimming holes!

Trip Itinerary

Day 1
  • Shuttle from St. George: 4 hours
  • Hiking Mileage: 5.4 miles
  • Elevation Gain: 300 feet

We will depart Saint George, Utah early this morning for the remote town of Escalante which is truly the heart of Utah’s Canyon Country. After reaching Escalante we will shuttle up to the Boulder-Mail Trailhead and have lunch while preparing for our cross country hike. The overland route from Boulder to Escalante features a sea of endless slick rock sandstone, deep twisting side canyons, spring-fed creeks, and towering Ponderosa Pines typical of Utah’s high canyons. Our hike today is 5.4 miles to a primitive camp overlooking Death Hollow – easily one of the most impressive canyons in the Grand Staircase-Escalante National Monument. The camp features a beautiful sandstone amphitheater and large natural water pockets teeming with Utah’s unique aquatic life forms such as Fairy Shrimp. Huge panoramic views a hearty dinner and endless desert star gazing are the order of the evening!

Day 2
  • Hiking Mileage: 6 miles
  • Elevation Gain/Loss: 1400 feet

Today we will wake up with the rising sun, pack our gear and prepare for the descent into Death Hollow. Death Hollow is large, deep and full of water – it gets its name from mules falling into the canyon as they attempted the mail route from Boulder to Escalante. As we descend deeper into Death Hollow we’ll be trekking through ankle-deep water. This canyon is filled with huge Ponderosa Pines and natural springs pouring out of the ancient Navajo Sandstone walls. Our destination this evening is Mamie Creek – a large tributary of Death Hollow which we will reach later in the evening to setup camp against a massive rock wall overlooking the canyon.

Day 3
  • Hiking Mileage: 6.5 miles
  • Elevation Gain/Loss: 400 feet

This morning we'll leave our camp setup while we explore downstream to see one of the most unique and interesting features in the region - the Mamie Creek Natural Bridge. The bridge is situated above a massive valley where Mamie Creek pours into Death Hollow. Today is all about exploration - and because we’ll be hiking most of our miles today with light day packs, today is also all about fun! After exploring the bridge we’ll head back upstream to our campsite, where we'll pack up and continue on just a couple of miles down trail to Antone Flat.

Day 4
  • Hiking Mileage: 6 miles
  • Elevation Gain: 1400 feet
  • Elevation Loss: 2000 feet
  • Shuttle to St. George: 4 hours

Today we will pack up early for the 7.5 mile trek across Antone Flats – which features a kaleidoscope of intricate Navajo slickrock formations, canyons and high altitude Ponderosa forests. The hike ends with a massive view into the Escalante River Valley and a steep descent off of the high plateau we’ve been traversing – the old mail route from Boulder to Escalante that bypasses the nearly impassable Escalante River Canyon! We rendezvous with our shuttle pickup around 2:00pm and then depart for St. George, which we should reach between 6pm and 7pm in the evening!

5-day Variation

The 5-day variation of this trip allows us to finish with a 14-mile traverse of the Escalante River, which runs through a breathtaking, signature Utah canyon. We skip our layover on Day 3 and instead continue on so we can spend two full days along the Escalante River.

Please note the public agencies that oversee this region require that everyone hiking in the Escalante River corridor pack out all solid waste, including human waste. We provide resources and training to make this manageable and efficient. However, if you'd rather embark on a trip in this region where that isn't required, we recommend participating in the 4-day version of this trip.

Please Note: We always do everything in our power to follow the set itinerary, however it can change occasionally based on temporary access restrictions, weather, lodging/campground availability, guest ability/injury, natural events like fires and flooding, and other potential causes.
