48 HOURS OF FALL IN BIG SKY

Plan Around a September Weekend Event

One of the best-kept secrets about fall in Big Sky is just how much is happening on the weekends in September. Before you pack your bags, check which of these signature events lines up with your trip — each one transforms an already-great weekend into something truly unforgettable.

• The Rut Mountain Runs — September 10–13, 2026: One of the most celebrated mountain running events in North America, The Rut takes place at Big Sky Resort over a thrilling four-day weekend.

Saturday: Arrive, Explore, and Celebrate

Morning: Fuel Up and Hit the Trails

Start your Saturday the right way. Grab a coffee and a fresh-baked pastry from Hero Snow Coffee in the Meadow Village Center, or swing by Blue Moon Bakery in Town Center for their famous hand-tied bagels and breakfast sandwiches. Either way, you'll want a solid foundation before heading outside.

Once you're fueled, lace up your boots and head for the hills. Fall is arguably the best time of year to hike in Big Sky — the cooler temperatures make longer distances more enjoyable, the trails are blissfully uncrowded, and the changing leaves on the aspen and cottonwood trees add a layer of color that summer simply can't match.

Top fall hikes to consider:

• Beehive Basin — The crown jewel of Big Sky hiking. This 6.6-mile round-trip trail climbs 1,500 feet to a stunning glacial cirque with a crystal-clear lake overlooking Lone Peak. Pack a lunch and take your time — you've earned the view. Note that at higher elevations, early snow is possible, so check conditions before you go.

• Porcupine Creek — A local favorite for its secluded feel and spectacular 360-degree vistas of the Gallatin Mountains. The trail winds through open meadows, dense woods, and rocky sections, with the sound of the creek as your constant companion. A perfect choice if you want to feel like you've discovered something all your own.

• Storm Castle — Located about 30 minutes from Big Sky in the Gallatin Canyon, this 5.2-mile out-and-back trail gains just under 2,000 feet and rewards the effort with sweeping autumn views. The cool fall weather makes it an ideal time to tackle this one.

As always, be bear aware on the trails. Pack plenty of layers, carry bear spray, and bring more water than you think you need. Check out our full guide to Fall hikes in Big Sky for more options.

Afternoon: Get Out on the Water or in the Saddle

After your morning hike, the afternoon is yours to explore Big Sky from a different angle.

Cast a line on the Gallatin River. September is one of the finest months of the year to fly fish in Big Sky. With summer crowds gone and fish feeding aggressively before winter, the Gallatin River comes alive with grasshoppers, Blue Winged Olives, and hungry trout. Local outfitters offer guided half-day and full-day trips for seasoned anglers and first-timers alike —all gear included. Book in advance, as fall dates fill quickly.

Explore on horseback. As the leaves begin to turn, there's nothing quite like taking in the fall colors from the back of a horse. Many local outfitters are still offering guided trail rides in September, giving you an intimate, unhurried connection to the land. Contact local outfitters to book your ride.

Go off-road. A side-by-side excursion is another fantastic way to get into Big Sky's backcountry. Local outfitters offer rentals and self-guided tours that take you deep into the rugged terrain on Buck's Ridge, with jaw-dropping views of Lone Mountain, Sphinx Mountain, and the Spanish Peaks. Check with outfitters for September availability, as the season typically runs through mid-October, weather permitting.

Evening: Dinner and the Weekend Event

As the sun dips behind Lone Mountain and the air takes on that golden-hour glow, it's time to clean up and head out for the evening.

For dinner, you have options for every mood:

• Date Night: Treat yourself to an unforgettable dinner out tailored to your mood. Reserve a table at Michaelangelo's for authentic Italian pasta and fine wine, head to Blue Buddha Sushi Lounge for creative rolls and fresh sashimi, or settle into Buck's for regional wild game like their signature Hunter's Lasagna, elk, and red deer.

• Casual & Crowd-Pleasing: For laid-back dining with plenty of space for families or larger groups, head down to Riverhouse BBQ & Events for slow-smoked barbecue and iconic riverfront porch views, especially striking in the fall light. If you're staying in Town Center, grab artisanal wood-fired pies and pasta at Ousel & Spur Pizza Co.

• Local Favorites: Tucked away from the main resort hub, these beloved community staples deliver warm hospitality and fantastic food. Visit By Word of Mouth/bywom bistro in the West Fork neighborhood for an upscale-casual vibe and inventive bistro dishes, or reserve a table at Olive B's Big Sky Bistro in Meadow Village for classic American bistro cuisine, fresh seafood, and a cozy local feel.

After dinner, lean into whichever weekend event brought you to Big Sky. If it's Rut weekend, the Mountain Village Plaza buzzes with post-race energy and camaraderie well into the evening. Oktoberfest means cold steins, live music, and dancing under the tent in Town Center. Film Festival weekend calls for an evening screening at The Waypoint — cinema with soul, set against one of the most stunning landscapes on earth.

Sunday: Slow Down and Savor

Morning: Stroll to Ousel Falls and Shop Local

Sunday mornings in Big Sky in September have a particular rhythm to them — unhurried, golden, and deeply satisfying. Start with coffee and ease into the day before heading out for a gentle walk through the forest.

Take the trail to Ousel Falls, one of Big Sky's favorite local escapes. The easy, 1.6-mile round-trip walk winds through lodgepole pine and aspen before arriving at a series of waterfalls along the South Fork of the Gallatin River. In early fall, golden leaves add a little extra color to the journey, and the sound of rushing water makes the perfect backdrop for a slow morning outdoors.

After your walk, spend some time browsing the shops in Town Center and Meadow Village. Pick up a locally made gift, find something cozy to take home, or settle in for a second cup of coffee while you watch the mountain do its thing.

Afternoon: One Last Adventure Before the Drive Home

Don't rush out. Big Sky rewards those who linger.

Tee off with mountain views. The Big Sky public golf course is still open in September, offering a stunning par-72 course with some of the most scenic views you'll find anywhere. A perfect blend of sport and mountain scenery — and with fewer players on the course, you'll have the fairways nearly to yourself.

Take a day trip to Yellowstone. Big Sky sits ~ 50 miles north of West Yellowstone, the gateway to the west entrance to Yellowstone National Park. Access through the west entrance is open to personal vehicles well through October but is weather-dependent. Fall is one of the best times of year to visit — crowds are dramatically lower, wildlife is more active as animals prepare for winter, and the cooler temperatures make spotting elk, bison, and bears along the roadways more likely. Even a two-hour loop through the park's northern reaches is enough to remind you why this place is one of the world's great wonders.

Before You Go: A Few Things to Keep in Mind

Fall in Big Sky is a transitional season, and a little planning goes a long way.

• Account for seasonal closures. Fall is the "shoulder season" in Big Sky, meaning many major summer attractions, activities, and services wrap up for the season. Notably, Big Sky Resort closes for summer operations on September 13. Many seasonal restaurants, shops, and tour operators also reduce their hours or close entirely until winter. Always call ahead or check official websites to confirm operational dates before heading out.

• Layer up. Fall weather in Montana can shift quickly — warm, sunny afternoons can give way to crisp evenings and, at higher elevations, early-season snow. Pack layers, a waterproof jacket, and sturdy footwear.

• Book ahead. Rut weekend, Oktoberfest weekend, and Food & Wine Festival weekend are among the busiest of the fall season. Reserve your lodging and dinner reservations well in advance.

• Be bear aware. Animals are actively preparing for winter in September. Carry bear spray on every trail and store food properly.
