Start at the lift plaza near the bottom of Chair 1 and look for the signs. They send hikers off the lower Danny On Memorial Trail onto an alternate route that follows a road above Russ's Street and rejoins the original trail below the bottom of Chair 5. That detour is still posted. According to the resort's Big Mountain Fuels Reduction Project page, it's one of several changes that outlasted the summer, even though all chairlifts and resort facilities closed for the fall in September.

Whitefish Mountain Resort's snow report dated Oct. 12 lists opening day as Friday, Dec. 4. Between now and then, the rules for walking, skinning and bringing a dog up Big Mountain change on set dates. Two of them come from the resort's own policies and three from the state hunting calendar. The resort dates are pegged to the scheduled opening, not to snowfall.

The calendar between now and first chair

The hunting dates come from Montana FWP's 2026 season calendar. FWP points readers to the regulations for district-specific details. The Nov. 20 date is 14 days before the scheduled Dec. 4 opening, which is how the resort defines pre-season. If opening day moves, that date moves with it.

Why the front side still looks different

The detours come from summer logging. The Flathead National Forest describes the Big Mountain fuels-reduction work as treatments on about 200 acres near Chairs 1, 2 and 4. The goal is to reduce wildfire risk and protect resort infrastructure and private property.

In its Sept. 21 update, the resort said logging had stopped and crews were cleaning up the affected terrain. It warned of hazards including felled trees, stumps and disturbed soil. Two bike trails, Freebird and Skynyrd, are still closed. Hikers who want a direct line to the summit can take the Toni Matt/Benny Up ski run, which is open. The resort asks anyone hiking or biking during the shoulder season to follow all signage and any directions from staff on site.

As of Oct. 12, the Sept. 21 note is still the latest update on that page. That means nobody has announced a reopening date for Freebird, Skynyrd or the regular lower Danny On. The posted signs on the mountain are the best guide to what's current on any given day.

Orange season overlaps everything that follows

Whitefish Legacy Partners runs the Whitefish Trail, and its maps and conditions page carries a standing reminder that hunting is allowed in the area. It asks trail users to wear orange and stay alert. The same page sets the trail's general dog rule: dogs must be leashed or under strict voice control, must not chase wildlife, and owners pick up after them.

FWP's archery season for deer and elk runs through Oct. 18. The general season opens Oct. 24 and runs through Nov. 29. That puts the first nine days of the resort's pre-season, Nov. 20 through Nov. 28, inside general season, with Nov. 29 as the last overlapping day. Anyone planning an early skin up the East Route in late November will be on the mountain during the general deer and elk season.

Nov. 20: the mountain picks one route

The Whitefish Mountain Resort uphill policy sets a pre-season and a post-season, each 14 days long, around the operating season. During those windows, the East Route is the only approved route for uphill and downhill traffic between 8 a.m. and 4 p.m. Before 8 a.m. and after 4 p.m., the policy sets no route restrictions.

The route itself starts at the Spruce lot. It crosses the bridge toward the Ski & Ride School, then follows lower Inspiration, Expressway, Moe Mentum and upper Russ's Street to the summit.

Pre-season is also the last stretch when dogs can go on the slopes. The policy allows them during the pre- and post-seasons if they're leashed and under control.

Dec. 4: passes, hours and a dog line at the parking lot

Once the lifts start, the uphill rules tighten in three ways.

1. A pass on display. Anyone without a regular winter season pass needs an uphill-only day ticket or an uphill-only season pass. Both are sold at Base Lodge Tickets & Information or online. The pass is printed on a 4-by-6-inch card that has to be visible to ski patrol on the way up, and you also need to carry a photo ID. Regular winter pass holders get an uphill season pass free, but they have to pick it up at the Base Lodge. Ski patrol tells anyone without a card to turn around.
2. Two routes, two time windows. During winter operations, uphill travel is allowed on the Benny Up route from 6 a.m. to 4 p.m. and on the East Route from 9 a.m. to 7 p.m. From 4 p.m. to 7 p.m., the East Route is the only approved downhill route. From 7 p.m. to 6 a.m., all uphill and downhill travel is prohibited.
3. Dogs stay at the car. During the winter operating season, dogs aren't allowed beyond the resort's parking areas.

That last change means a dog walk that's allowed on Dec. 3 isn't allowed on Dec. 4. Owners who walk their dogs up Big Mountain in late fall have until the day before opening, and only while the dog is leashed.

The new trail coming off Chair 3

The biggest addition to Big Mountain's trail system isn't fully public yet. According to the Whitefish Pilot, Whitefish Legacy Partners and the resort built about 3 miles of new Whitefish Trail running from the top of Chair 3 down to the Big Mountain Trailhead area. The plan is for it to eventually connect with trails in the Haskill and Hellroaring basins. Runners in the Oct. 3 Whitefish Trail Blazer 50K got the first organized look at it. The Flathead Beacon reported that a grand opening was planned for October.

As of Oct. 12, we haven't found a published opening date, an official name for the segment, parking directions or any direction-of-travel rules. Until Whitefish Legacy Partners announces those, treat the section as pending.

Lower on the hill, where the trail system has a new home base

The trail race also introduced the Whitefish Legacy Center, a 35-acre property that used to be the Whitefish Bike Retreat. Whitefish Legacy Partners now owns it, and it officially opened in July. "We hosted the event here for years, but we never really had control over the space," program director Jedd Sankar-Gorton told the Whitefish Pilot. The property is open dawn to dusk all year. Fall hours for the Welcome Center haven't been posted.

Two Whitefish Legacy Partners events fall before rifle season opens:

• Fall wild mushroom hunt: Oct. 13, 5:30 to 7 p.m., at the Woods Lake Trailhead. It's free and family-friendly. Bring bear spray and a basket.
• Stargazing on the trail: Oct. 17 or 18, 7:30 to 9:30 p.m., at Holbrook Overlook, weather permitting. RSVP to get the final date or a cancellation notice.

Two schedules off the mountain that run on the same clock

Grouse Mountain Lodge's restaurant is set to close for renovations in November. In December, the lodge plans to serve its current menu from its new event space, and a new open-hearth restaurant is targeted for mid-to-late spring, the Whitefish Pilot reported. The property is scheduled to return as Hotel Whitefish by June 2027.

On US 93 west of Whitefish, the Montana Department of Transportation's Oct. 9 update put curb-and-gutter pours in the week of Oct. 12, with paving to begin the following week or the week after. Work stops for winter, and final activities resume in spring 2027.

If you're weighing a home on the Big Mountain Road side of town, the uphill hours, the dog rules and the pre-season dates are part of what that address gets you each winter. Liz McGavin can walk you through how those patterns show up in the properties near the mountain, or prepare a complimentary valuation if you already own one.
