Arrastra Creek Trail

One of many access points to the Bob Marshall Wilderness Complex, the Arrastra Creek Trail heads up through a narrow stream valley into the heart of the Montana backcountry. Starting at the Arrastra Creek Trailhead, hikers gradually climb through conifer forests and open meadows, with breathtaking views of the surrounding mountain slopes. The trail itself is relatively straight, but beware of blind corners, as this is major bear country; be sure to make plenty of noise and always carry bear spray. Besides bear, hikers have ample opportunity to spot other types of fauna, including elk, deer, rabbits, butterflies, and eagles, and from late spring through mid-summer, hikers will be treated to a spectacular wildflower display. Twice during the hike the trail crosses Arrastra Creek, so be sure to use extra caution during high water season. Just before the second crossing, a crossroad with the 3.1 mile-long Porcupine Basin Trail is available to hikers looking for a longer day trip. Another option is to go the full 8 miles into the Bob Marshall Wilderness; the trail hooks up with the Dry Creek and Mainline Trails, which grants a hiker access to all the trails in the protected area.
