High upon Mount Sentinel on the east side of the University of Montana campus is the famous white “M” emblazoned on the side of the mountain. This massive uppercase letter has existed in some form since 1908, and what was once established to represent the University now stands as an emblem for Missoula and a destination marking one of the state’s most popular hiking trails.

Scroll below to learn a brief history about the “M”, get the deets on hiking its 13 switchbacks (including where to park), and how you can keep this Missoula symbol in good condition for years to come:

History of the M Trail

The University of Montana was founded in 1893 with a bare Mount Sentinel rising above campus. It wasn’t until 1908 that a cohort of forestry students lugged up hundreds of whitewashed rocks to form the original M – creating a century-long legacy that still stands in spirit today. 

The “M” evolved into a wooden structure after the whitewash rocks faded and rolled away. In 1968, the concrete “M” was laid, representing a more permanent structure still seen today. The “M’ still gets occasional paint touch-ups, but otherwise it’s the same “M” that people have been hiking toward for nearly the last 50 years.

What You Need to Know

The “M” trail traverses 13 switchbacks and approximately 0.75 miles as it ascends 620 feet of elevation gain. While some Missoula athletes can run the entire way to the “M”, others might be surprised by the constant uphill travel. Several benches are situated at the switchbacks, with the views getting better and better the higher you go. 

Expect ice and use shoe spikes when traveling the trail in the winter. You can also expect a lot of other people on the trail no matter the time of year, including pets. The route gives incredible views of UM’s campus, including Main Hall and The Oval, alongside the University District, and once you get to the top, the entire city unfolds beneath your feet.    

Where to Park 

The main trailhead for the “M” hike is on Campus Drive, behind the Adams Center and across from Aber Hall, near the University Center (aka the UC). The parking lot sits next to the small Phyllis Washington Park. A parking permit or parking fee is required during weekday university operating hours (9:30am – 4:00pm), but is free in the evenings and weekends.  

What to Bring 

Assess your experience level. Hundreds of hikers complete the “M” trail with nothing more than the shoes on their feet. But water in hot weather, shoe spikes during the winter, and walking poles for achy knees can make a big difference. The trail is dirt and rock the whole way through, so comfortable shoes with traction are recommended.  

Important Information

The “M” hike sees thousands of hiking boots throughout the year. Erosion is a substantial danger to the trail and Mount Sentinel ecosystem – so it’s pivotal to always stay on the trail when exploring.  

More Hikes On and Around Mount Sentinel 

The “M” Trail is just the tip of hiking routes across Mount Sentinel. The “M” itself is not even halfway up the entire mountain, and the trail continues all the way to the top for a more challenging endeavor. Moreover, additional trailheads, like the Maurice Trailhead on the south side of the University District, offer additional ways to explore Mount Sentinel. 

Look north across the Clark Fork River toward Missoula’s other prominent peak, Mount Jumbo, with the large letter “L” emblazoned on its side (standing for Loyola Sacred Heart High School). Mount Jumbo is also a treasure trove of hiking trails in a city with hundreds of miles of trails to explore.

Support the M Trail

The “M” Trail is one of the most popular hiking trails in the state, and due to its heavy use, maintainance is required throughout the year. This includes erosion control, signage installation and the upkeep of those pivotal benches along the way. 

The University of Montana offers merchandise and direct contribution opportunities to help support the “M” trail and all that it stands for. If you want your own “I hiked the M Trail shirt”, or if you want to donate directly, visit the link below:
