Across the Divide


  •   The Continental Divide at 12,000+ ft
  •   Tremendous mountain views
  •   Glacial-carved valleys
  •   Alpine tundra and snow-fed waterfalls
  •   Abundant wildlife habitat
  •   Rushing streams, lakes & alpine


Our 5-Day Across the Divide backpack takes us from the rivers that flow east into the Atlantic, to the very headwaters of those that make their way west to the Pacific - and we do it all under our own power! We’ll begin along the waters of the pristine Big Thompson River, follow the drainage up past roaring waterfalls, alpine lakes, and glacial-carved granite cliffs. Then we'll ascend above the clouds, over the Divide, and down into the river valleys flowing west out of the mountains!

Days one and two we’ll ascend through a long and lake-strewn canyon with views of high peaks above - on day three we’ll make our way up and over the continental divide. This is the crux and highlight of our trip - we’ll likely see elk, quite possibly bighorn sheep, and if we’re alert we’ll glimpse the white-tailed ptarmigan above tree line as we pass. Days 4 and 5 we’ll continue through the wildlife - rich forests of the western slope as we descend to our final destination and the return trip by shuttle through the alpine tundra to Estes Park.

Trip Itinerary

Day 1
  • Shuttle to trailhead: 20 minutes
  • Hiking Mileage: 3.8 miles
  • Elevation Gain: 1,380 feet

This Rocky Mountain National Park backpacking trip starts with a brief shuttle to our trailhead - we’ll hike along the Big Thompson River, with stops at "Arch Rocks" (granite boulders of a reddish -orange and in fantastic shapes) and "The Pool" (a massive whirlpool of churning water) along the way.

After a hearty lunch we’ll continue to the serenade of rushing water as we ascend through the canyon to Fern Lake, our home for the night.

Day 2
  • Hiking Mileage: 2.2 miles plus optional day hike
  • Elevation Gain: 570 feet

Today we’ll continue in the presence of mountain water: from rushing rivers and waterfalls, to high mountain lakes. Our hike will take us through the reaches of Odessa Gorge, a land of towering cliffs, wildlife, and wildflowers.

This is our shortest day with full gear on our backs, and provides multiple options for side hikes together to more remote mountain lakes and waterfalls off the beaten path.

We’ll camp within earshot of the creek, near an alpine lake nearing tree line, at 10, 600 feet, where a hearty dinner awaits as we settle in and prepare for our divide traverse and our longest day the next morning.

Day 3
  • Hiking Mileage: 7.9 miles
  • Elevation Gain: 2,370 feet
  • Elevation Loss: 1,570 feet

Day 3 is the most difficult and in some ways the most stunning of our trip. We’ll rise before the sun, eat a hearty breakfast, and make our way out of Odessa Gorge to the heights of Flattop Mountain at 12, 324 feet. This route will take us into the higher reaches of the National Park - we’ll see glaciers, likely Rocky Mountain Bighorn, and we’ll spend much of the day in the alpine zone, where we can see to both sides of the Continent for unending miles.

From Flattop Mountain we’ll traverse south through the tundra into the Park’s western forests and the North Inlet creek. Our camp is just below tree line in the high spruce/fir forests that abound on the western slope of the Park.

As evening descends we’ll enjoy a well-earned dinner and listen to the creek as it murmurs past us near camp.

Day 4
  • Hiking Mileage: 5.2 miles plus optional morning hike
  • Elevation Loss: 1,700 feet

After breakfast, we’ll break camp and head down into the valley of North Inlet creek. Today’s walk provides a great time to take a closer look at the flowers and wildlife of the subalpine forest, as we move through an area rich in Elk, Moose, and Rocky Mountain wildflowers of infinite variety.

Our final evening we’ll camp once more to the sound of rushing water, with limitless stars above, as we reflect on the journey of days past and those to come.

Day 5
  • Hiking Mileage: 4 miles
  • Elevation Loss: 700 feet
  • Shuttle to Estes Park: 1.5 hours

Our final day together we’ll enjoy a leisurely breakfast and pack up for our final 4-mile stretch to the North Inlet Trailhead. We’ll then enjoy a shuttle up and over the Divide along Trail Ridge Road, the highest continuous road in the Lower 48! We'll stop for a picnic lunch and officially end our trip in Estes Park, where we began, having come full circle across the Divide and back on Trail Ridge Road.

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.
