Hike near stunningly clear alpine lakes, in large open meadows, and through immense limestone valleys on this spectacular trek. Located in the northeastern portion of the Bob Marshall Wilderness Complex, the Swift Dam reservoir is where this journey begins.

During our trip, we explore the beautiful rock pools and small slot canyons of the South Fork of Birch Creek as well as the astounding Big River Meadows nestled just below the Continental Divide. After several days of hiking, the Trilobite Range emerges, towering above Clack Meadows and the Trilobite Lakes, which are nestled just below the impressive peaks. Here, the lakes beckon you to dip your toe in, and Trilobite Peak awaits a few hardy souls to summit her ridge to see the grandeur that unfolds around her.

This trip is meant for the hiker who wants a little bit of everything—wildflower viewing, peak climbing, river walking, and alpine lake swimming. Please call or email for more details.

Trip Rating Definitions

5 - 8 mile travel days along river grade trail with some undulating terrain, but no major changes in elevation. All hiking is on maintained trail.

6 – 10 mile travel days with some of those days requiring changes in elevation of 500 – 1200 ft. over several miles. Short portions of route may be off-trail.

Moderately Strenuous
7 – 12+ mile travel days with some days having a combined change in elevation totaling 2,500 feet, or more, over several miles. Off-trail hiking and routing finding with short portions of limited exposure possible.

7 – 12+ mile days with regular changes in elevation over a few miles. Frequent off-trail hiking over uneven terrain with areas of exposure and route finding involved. Previous backcountry experience required.

*Please note these descriptions are used for travel days only and are our attempt to provide a rating for the overall trip difficulty. On layover days we will offer optional hiking opportunities that may not be in keeping with the rest of the trip difficulty rating.

Additionally, changes in elevation are meant to represent the days’ starting and ending elevations not necessarily the total elevation lost and gained throughout the course of the day. If you have questions or concerns regarding trip difficulty and your abilities please contact us.
