Trip Highlights

  • Remote Off Trail Hiking

  • Waterfalls, Alpine Lakes & Wildlife
  • Secluded Camps Far from Trailheads
  • Point to Point Thru-hike

Please Note:  This trip was affected by the 2020 wildfires in Rocky Mountain National Park. The Park Service has not indicated yet whether this area will be open in 2021, or what condition it will be in. For the time being, we are not adding 2021 reservations for this trip. We heartily recommend our Rocky Mountain High Alpine AdventureLongs Peak Loop Trek, and the Alpine Peaks, Lakes & Waterfalls Thru-hike as excellent alternatives!

The Mummy Range of Rocky Mountain National Park is a seldom visited wilderness treasure. Off the beaten path and high in the mountains is where you will tread on our Mummy Range backpacking trip! This mountain adventure is five days long and four nights of Rocky Mountain tranquility. Not to be taken lightly, this is one of our more challenging hikes as it includes longer trail mileage, as well as both on- and off-trail travel. It rewards with sweeping views, potential wildlife viewing, pristine camps and scenery, and overall unforgettable trekking!

We’ll start in a broad river valley and climb to higher elevations as we cross the Tundra fields of the high Mummy Range on Day 3. We will trek through quiet forests of lodgepole pine, past pristine mountain lakes, high altitude snowfields and over the rugged alpine tundra above tree line at 11,400 feet. This is a beautiful and remote corner of Rocky Mountain National Park and the solitude here is unmatched. Don’t be surprised to see vast elk herds or if a moose happens to walk into camp while your guides are cooking up dinner one night!

  • Shuttle to Trailhead: 1-hour drive
  • Hiking Mileage: 6 miles
  • Elevation Loss: 500 feet

We’ll begin this Rocky Mountain National Park backpacking trip from a trailhead off of Old Fall River Road, the original road over the Continental Divide. Our drive winds us up steep mountain passes to where we’ll begin hiking at Chapin Pass Trailhead. Our first day of hiking is a great warm-up and features stunningly beautiful valley hiking. The high mountains are all around us as we wind our way through tall grass meadows and deep forests along Chapin Creek. We then follow the Cache La Poudre River to our camp at its junction with Hague Creek.


  • Hiking Mileage: 2.6 miles (plus optional day hike)
  • Elevation Gain: 1,000 feet each way

Today’s a short day that will take us into the high country. After a hearty breakfast and relaxing morning, we’ll set off to our next camp, which is at an elevation of nearly 11,000 feet. Our hike stays in the trees until we reach our destination, which is at the edge of treeline. We’ll set up camp, eat lunch, and then hike to Mirror Lake (3 miles roundtrip), which is a beautiful mountain lake sitting in a classic Rocky Mountain cirque. That evening we’ll enjoy a big dinner and relaxing evening before turning in.


  • Hiking Mileage: 9 miles
  • Elevation Gain: 2,000 feet

Day 3 is the gem and the crux of this trip. We’ll get a very early start and be hiking before sunup, as most of today’s journey is above treeline, and we must be back down before the thunderstorms roll in. We’ll hike on-trail up to Mummy Pass (11,300 feet), but from here we’ll be hiking off-trail across some truly breathtaking high country dotted with alpine lakes and glaciers! We’ll ascend Skull Point (12,026 feet) and Sugarloaf Mountain (12,101 feet) before joining with another trail and following it to camp. All in all, we’re going to cover over 4 miles off trail and above treeline, soaking up some of the most amazing views you’ve ever seen! Tonight’s camp is a welcome refuge where we’ll enjoy a huge dinner.


  • Hiking Mileage: 7 miles
  • Elevation Loss: 1,800 feet

Awaking to another morning in the mountains, we will enjoy a leisurely breakfast as the trail is mainly downhill from here out. After packing camp, we have a 4 mile hike along the Thompson River to our next campsite. Shortly after camp we will pass by the tumbling white water of Lost Falls. A little further we will stop and take time to hike to Lost Lake. After our exploration we will continue on with our packs to camp. If there are no fire bans, we will bring our last evening to a close with a campfire under the starlight.


  • Hiking Mileage: 5 miles
  • Elevation Loss: 1,500 feet

We will enjoy our last morning in the wilderness, and begin our descent from the high country. Continuing down trail along the beautiful Thompson River Valley, 5 miles to the Dunraven Trailhead. The mountain peaks continue to surround us as we soak in the last of our time in the backcountry.

For optimal taste and energy, we supplement all our meals with spices, herbs, oils, cheeses, butter, sugar, and fruits and vegetables (fresh and dried). In addition, we provide you with with an assortment of trail mix, snacks, and dried fruits to eat at your own discretion.

We regularly accommodate vegan, vegetarian, kosher and non-gluten diets and will make adjustments for food allergies. These and other special dietary requests may require an additional fee.

Additionally, some guests choose to bring their own sleeping bag. We supply high quality, synthetic fill bags that are professionally laundered after every trip.

If you’re able to bring your own down sleeping bag, there are multiple benefits. If not, we’ve got you covered!

Being a high mountain environment, the Rocky Mountains are prone to sudden temperature and weather shifts. This is an exciting aspect of being in Colorado’s high country. On trips in June, snow is a slight possibility, and the rest of the summer rain is always a possibility on your trip. To be fully prepared, please follow the recommended clothing list closely (this list comes as part of your trip packet when you register). See below for average summer temperatures:

Average Temperatures (Fahrenheit)
High / Low





Sleeping on backpacking trips is in premier 1-person, 2-person or 4-person backcountry tents. Solo travelers, and anyone else who requests it, are issued single tents.

We never use dehydrated backpacking meals, instead serving freshly prepared, delicious backcountry cuisine made with a variety of common and specialty ingredients that travel well in the wilderness.



Of course campsites vary tremendously by destination, trip and even by the individual day of a trip. However, you can expect to camp in beautiful areas that put you right in the action to make the most of your backpacking adventure. We carefully design our itineraries with campsites in mind.
