Experience the rugged peaks and crystalline lakes of the Trilobite Range in the Bob Marshall Wilderness of Montana. This 10-day backpacking loop affords you an opportunity of adventure like no other. It’s the most strenuous, most adventurous, and longest trip we offer. With all you need on your back and a trip long enough to truly forget what day it is, this is wilderness immersion at its finest. From Argosy Peak (8,155’) to Pentagon Mountain (8,873’) to the north end of the Chinese Wall, this backpack explores some of the wildest country in the Bob.

This excursion includes several layover days to climb peaks or enjoy a good book in the high country. The moving days are mostly on-trail, but a few include off-trail travel with a full backpack. With one food drop mid-way through the trip, your average backpack weight is typically between 35 and 40 pounds. You may encounter downfall, snow patches, and high water on this trip. It is important to be in very good physical shape, and previous backpacking experience is necessary. One client on a past backpacking trip put it well when she said she’d “never been on a trip that had been so physically invigorating and completely relaxing at the same time.”

The backpack trip circumnavigates the Trilobite Range, which is over 10 miles long. You will spend several days hiking beneath its towering peaks and ridges, exploring little tarns and larger lakes while witnessing the lush early summer beauty of snowmelt, sunshine, and wildflowers galore. You will also have the opportunity to climb several peaks along the way. If you’re looking for true wilderness adventure, solitude, and a serious physical challenge, this is the trip for you.
