Big Mountain Fuels Reduction Project

Throughout summer 2026, Whitefish Mountain Resort and the U.S. Forest Service are undertaking a fuels reduction project across more than 200 acres of Big Mountain terrain. Occurring in phases, this work involves felling trees and clearing vegetation to reduce wildfire risk and protect resort infrastructure.

Work involving heavy machinery will take place in the orange-shaded areas on the map. This will impact hiking and mountain biking trails at various times throughout the season. For your safety, please heed all signage and follow this page to learn about current trail closures and reroutes.

JULY 21 UPDATE:

Logging crews continue working around the Wood Lot ski run under Chair 2. Big Ravine also is closed to all foot traffic as crews transport logs downslope.

Trucks are moving felled trees out of the Chair 4 area via the Expressway and Corkscrew ski runs and the Alder parking lot. Staff will be present today to facilitate foot traffic along the route.

Hikers: Hazards and obstructions remain on the lower section of the Danny On Memorial Trail. A reroute remains in place.

Starting from the lift plaza near the bottom of Chair 1, please follow signs and ropes that will guide you onto the alternate route, which includes a dirt road above Russ's Street. The detour connects to the original trail below the bottom of Chair 5.

Additionally, the Toni Matt/Benny Up ski run is open and hikers may take this direct route to the summit.

Mountain bikers: All three sections of the Whitefish Bike Park are open, with Chairs 1 and 10 running daily and Chair 2 running on Saturdays and Sundays.

Three trails — Freebird, Skynyrd and Limelight — are closed due to logging.

On the Summit Trail, please note a small section of a switchback has been rerouted where the trail crosses Mully's ski run. Signs are in place.
