Do you want to have an unforgettable adventure this summer? If so, the Thorofare backpacking trip is for you! This trip is a 7 day/6 night hiking adventure into the headwater basin of the Yellowstone River, arguably the most pristine and remote area in the Continental United States. Rich with wildlife, mountain views, vast meadow systems, roaring rivers, crystal clear creeks, and feeling of wildness, this trip is truly spectacular!

We catch a boat shuttle from Bridge Bay Marina to the beginning of our hike along the eastern edge of Yellowstone Lake. From here we hike to the South end of the lake, where the mouth of the Yellowstone River marks the beginning of the Thorofare Country. For 3 more days we hike up the Yellowstone River into some of the most remote wilderness in the continental United States. The chances of seeing wildlife are very good (although never guaranteed of course), as this area is the Eden of Yellowstone’s animal habitat. Bring your fly rod along if you’re a fisherman, and you’ll have the opportunity to catch 20 inch native cutthroat trout. Bring your camera along if you’re a photographer, and you’ll be shooting pictures of the most pristine area in Yellowstone. On day 5 we begin our hike back to Yellowstone Lake, exploring and scouting for wildlife along the way.

Need to Know: March 1st Permits

Due to Yellowstone’s permit system, which issues backcountry hiking and camping permits on March 1st each year, it’s beneficial to register before February 28th of the year you’d like to hike with us. Give us a call at 1-800-715-HIKE (4453) to learn more!

Day 1

  • Shuttle to Trailhead: 2.5-hour drive
  • Hiking Mileage: 8.2 miles
  • Elevation Gain: 100 feet

This unforgettable Yellowstone backpacking adventure starts from Bridge Bay Marina on the north end of Yellowstone Lake, where we catch a boat shuttle that will drop us off 9 miles away along the the Southeast Arm of the lake. During the boat ride, and also once we’re hiking, we’ll have fantastic views of Mt. Doane and Mt. Stevenson. Dot and Frank Islands meanwhile aid in grasping the size of Yellowstone Lake. It is over 20 miles long, 14 miles wide and 300 feet deep. Scientists believe it is part of the ancient caldera of Yellowstone’s supervolcano. Once on shore, we’ll hike 8 miles to our camp at Beaverdam Creek, which marks the beginning of the valley of the Upper Yellowstone River. Camp for the evening is atop a bluff overlooking the creek and the expanse of the Thorofare!

Day 2

  • Hiking Mileage: 7.3 miles
  • Elevation Gain/Loss: marginal

After crossing Beaverdam Creek we hike through thick willows and enter the broad meadows of the upper valley. Moose are sometimes encountered lounging among the willows. Another mile of hiking brings us to burned forests from the fires of 1988. Now over a quarter century old, the cleansing, regenerative effects of the fire are clearly evident. We’ll make camp this evening in the vicinity of Trapper Creek, with spectacular views of the Trident (a series of rocky escarpments) to the south and Turret and Table Mountain to the east. Occasionally wolves can be heard howling from this part of the valley in the late evening and early morning.

Day 3

  • Hiking Mileage: 7.5 miles
  • Elevation Gain: 450 feet

The next morning we’ll hike deeper into the Thorofare, as our trip continues south, paralleling the Yellowstone River. Often following grizzly or wolf tracks on the trail, we continue to scout for wildlife as we hike. We’ll hike a short distance downstream from camp to a large tributary of the Yellowstone River named Mountain Creek. We’ll depart the valley here and hike upstream along Mountain Creek to its junction with Howell Creek. We’ll then hike a few miles up Howell Creek to camp near the park boundary. We’ll have the opportunity to sleep in one of the most remote areas of the Continental United States.

Day 4

  • Hiking Mileage: 4-10 miles (optional day hike)
  • Elevation Gain/Loss: 1250 feet

Day 4 is exciting for two reasons. The first is that we’re not moving camp! We’ll sleep in and enjoy a delicious breakfast before embarking on a spectacular day hike to Eagle Pass, the second exciting part of the day. Several miles up Howell Creek the trail steepens and ascends through classic Yellowstone subalpine terrain to Eagle Pass. This will place us just below Eagle Peak, the highest peak in Yellowstone at 11,358 feet. Here we will have brilliant views of the wild and beautiful Absaroka Mountains to the east.

Day 5

  • Hiking Mileage: 6.5 miles
  • Elevation Loss: 350 feet

On day 5 we’ll begin our hike back toward Yellowstone Lake, enjoying the wildlife, wildness and views as we go. The views hiking back north are very different than they were on the way in. As we hike we’re watching the Yellowstone River flow into Yellowstone Lake and the Gallatin Mountains in the distance. Our camp will be near the Yellowstone if not right on its shores.

Day 6

  • Hiking Mileage: 9.9 miles
  • Elevation Loss: 150 feet

Day 6 we’ll continue hiking back through the Yellowstone River valley to a camp right on the shores of Yellowstone Lake.

Day 7

  • Hiking Mileage: 4.6 miles
  • Elevation Gain/Loss: marginal
  • Shuttle: 2.5-hour drive

On day 7 we’ll hike along the eastern edge of Yellowstone Lake and catch the boat shuttle back to Bridge Bay Marina. A comfortable drive through Yellowstone National Park back to our hotels ends this amazing backpacking 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.

Weather in Yellowstone

Being a Northern mountain environment, Yellowstone is prone to sudden temperature and weather shifts. This is an exciting aspect of being in Yellowstone.

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 in Yellowstone:

Fresh & Delicious

Meals from breakfast Day 1 through lunch the last day are fully included and prepared by your guide.

The trip was excellent

14 days ago

We had an amazing experience trekking the Thorofare with Rosey who is a fantastic guide. It was a beautiful trip where we were able to be out in the wilderness barely seeing another soul and really feel fully immersed. The veiws and landscape were always breathtaking and our trip up to eagle pass was wonderful. I also loved the campsites- being able to take in the surroundings, in particular the amazing stars at night and the milky way and also hearing the wolves howling. Rosey really made the trip for me, she was extremely professional throughout making sure everyone felt completely safe even in the wilderness, she gave us all the information we needed at all points of the trip and was very knowledgeable. The best part was that she made it a really fun experience also, by always engaging and joining in with all the guests on the trip. Thank you so much Rosey for making it such a memorable experience!

10 out of 10 trip

14 days ago

10/10 recommend this backpacking trip! The environment of Yellowstone is incredible on its own and there is a true backcountry feel to this trek. We had a wonderful group led by our guide Rosey who turned an already amazing trip on its own into something extraordinary! She is extremely knowledgeable and I loved listening to her share her knowledge with us. She is so personable and made efforts to connect with each guest in a really special way. She is professional, a great teacher, and a supportive and safe guide. She made us all feel safe in the wild backcountry, and I certainly left understanding the animals in this environment more.

Unforgettable Adventure

1 month ago

Everything about this adventure was 5 stars - from the initial booking, to preparatory advice, to COVID-related logistical changes, to the trip itself. I dealt with many different representatives during the planning phase and each one was responsive, informed, and patiently answered numerous questions. Ron spent nearly an hour advising me on gear options to address an unforeseen health issue before the hike, and our guide Matt Maar was nothing short of perfect. He was professional, attentive, patient, incredibly knowledgeable about the area, plants, and wildlife, and took exceptional care of us, constantly working to make sure we were safe and comfortable. Every meal he prepared for us was beyond special – I could have never imagined eating so well in the back country! The hike is challenging enough to make it feel like a great accomplishment, but not insurmountable for anyone who’s in good shape or willing to train. And the gift of the Thorofare makes every step worthwhile. It is truly a magical place that I will never forget. The expansive, pristine landscape that unfolds before you around every turn makes time stand still. The wildflowers were breathtaking. And the quiet solitude, sunsets, and starry starry nights unforgettable. Thank you Matt for a truly off the charts adventure of a lifetime. I’m looking forward to future treks!
