If you're looking for a solid climb with incredible payoffs, the Mount Sentinel via Crazy Canyon trail delivers. This route winds through thinned Ponderosa Pine forests, gradually revealing expansive views of the Missoula Valley and the winding Clark Fork River. Keep an eye out for the notable "Grandfather Tree" as you ascend, and in May and June, the trail bursts with wildflowers. The final push to the 5,158-foot summit of Mount Sentinel is steep, but rewards you with vistas stretching to the Bitterroot and Sapphire mountain ranges.
Planning your visit is easy, as the Crazy Canyon trailhead offers good parking and convenient bathrooms. This moderate 3.5-mile (5.7 km) hike, with its 1114 feet (339 metres) of elevation gain, typically takes about 1 hour and 45 minutes. It's a dog-friendly trail, but remember to keep your furry friends on a leash to protect the local wildlife. Consider an early start to enjoy the cooler temperatures and avoid peak traffic.
This trail serves as an excellent alternative to the more heavily trafficked "M" trail for reaching the summit of Mount Sentinel, offering a similar challenge and equally stunning views with potentially fewer crowds. It's a multi-use path, popular for hiking, trail running, and even snowshoeing in winter. The trail also connects to other routes, like the Hellgate Canyon Trail, providing options for longer or varied adventures if you want to explore more of the Missoula area.
