It’s Easy to See From Highway 93
While Trapper Peak isn’t one of the tallest peaks in Montana, it’s one of the most iconic.
Its visibility from Highway 93 and popular historical marker stops most visitors, and many locals get the pleasure of seeing the peak daily from home or work.

Although not as dramatic as the view from Highway 93, you can also see the summit from the south as you travel the West Fork Road (Hwy 473) towards Painted Rocks Reservoir.
You can see it from just about everywhere around here.
Along with Lake Como and Skalkaho Falls, it’s one of the iconic natural features of the Bitterroot Valley.
Trapper Peak’s Formation
Tens of millions of years ago molten rock rose to the earth’s crust, then cooled to form huge expanses of granite rock that formed the Bitterroot Mountains.
Tectonic plates were colliding, magma was pushing from below, and the entire top of the Bitterroot Mountains slid dozens of miles to the east.
It was time for new peaks to emerge, and Trapper Peak was born.
Our Bitterroot Mountains article has a fascinating video that explains how the Bitterroot Mountains were formed, and it’s quite the story.
View from Trapper Peak
Flash back to a couple million years ago and this area was mostly covered in glacial ice.
Things looked a lot different around here during the Pleistocene Ice Age.
Huge glacial ice sheets were on the move, and they were cutting U-shaped canyons in the Bitterroot Mountains until they melted about 15,000 years ago.
Trapper Peak’s jagged granite peaks, horns and circs were carved and shaped by these glaciers, leaving behind the spectacular scenery we enjoy today.
It’s a Challenging Hike
Anywhere you find 10,000′ peaks, you’ll find hikers, climbers, and peak baggers heading to the top.
So it’s no surprise that hiking to Trapper Peak is a popular summer activity in the Bitterroot Valley.
The most popular route to the summit is the Trapper Peak Trail, which begins at the Trapper Creek Trailhead located at the end of Forest Service road 5630-A.
The trailhead sits at an elevation of approximately 6,400 feet.

From there, the trail climbs 3,800 feet over 4 miles one-way to reach the summit of Trapper Peak at 10,157 feet.
As the excellent video below shows, most of the trail passes through pristine sub-alpine forest on a well maintained, but steep trail.
Once you emerge from the tree line, things become a little more challenging as the trail is less obvious and there’s plenty of scrambling on the loose rocky trail.
Technically, Trapper Peak’s summit is a year-round destination, but only experts would consider taking it on during the winter months, and we’re guessing that list is short.
Snowshoes, crampons, and ice axes in the snow and cold seems like the hard way to take in the views from the highest point around.
But even in the summer months it’s moderately difficult hiking, and hikers should be prepared with plenty of water and extra layers as weather can change quickly around here.
Hikers should also be prepared for snow or ice on the trail, and ensure they have all the necessary gear for a safe journey.
If you’re planning a trip to Trapper Peak, be sure to consider the time of year, weather conditions, and your physical fitness for this demanding hike.
Location and Access
To reach Trapper Peak from Darby, MT, head south on US Highway 93 for 4.3 miles, then turn west onto West Fork Road (State Highway 473).
If coming from the south, you can access West Fork Road via Conner Cutoff Road, approximately 23 miles north of Chief Joseph Pass on the Montana-Idaho border.
Once you’re on the West Fork Road, drive about 7 miles west until you see signs for Forest Service Road 5630.
Hiking to Trapper Peak
Make a right turn and follow a winding gravel road for roughly 5 miles.
You’ll come to a fork in the road where you should veer right onto FS Road 5630-A.
The final stretch is often rugged, particularly during spring when conditions can be wet or muddy.
Look for the parking area and markers indicating the start of Trail #133, where your hike to the summit begins.
