Halloween in the Flathead Valley & Around Flathead Lake: 2027 Guide

Fall in Montana has a special kind of magic. The summer crowds begin to thin, the mountains take on their first dusting of snow, the tamaracks turn golden, and communities throughout the Flathead Valley start getting ready for Halloween.

While many 2027 event dates and details will be announced later in the year, several Flathead Valley Halloween traditions return annually. If you're planning a spooky Montana getaway, here are some events and experiences to keep on your radar for October 2027.

The Curse of Blackwater Mountain at Flathead Lake Alpine Coaster Halloween in the Flathead Valley

Looking for a Halloween experience that is more than just a haunted house?

At The Curse of Blackwater Mountain, guests must enter the haunted trail, face what lurks within and then survive two rides on the Alpine Coaster to break the curse.

But your journey isn't complete after the first ride. The haunted attraction features live scares, frightening characters and a dark, immersive atmosphere, making it best suited for guests 13 and older.

The event takes place every Friday and Saturday night in October from 8PM to 10PM. Tickets are first come, first served and do not reserve a place in line, so arriving early is strongly recommended. Doors open at 7:45 PM.

Younger Halloween fans aren't left out. Guests 12 and under can visit the Flathead Lake Alpine Coaster during the daytime while the Halloween decorations are on display, but daytime visits do not include live scaring.

Get Lost at Fritz Corn Maze

Fritz Corn Maze in the Flathead Valley has become a seasonal tradition, offering fall activities for families and spooky experiences as Halloween approaches.

For families with younger children, visiting during the day is a great way to enjoy the fall atmosphere without the intensity of a nighttime haunted attraction. Older kids and adults can keep an eye out for haunted activities later in the season.

Pick a Pumpkin at Sweet Pickin's Pumpkin Patch

Before Halloween arrives, make time for one of the most classic fall traditions: picking out the perfect pumpkin. Glacier national park in the fall glacier in autum fall in mt fall in flathead lake fall in flathead valley pumpking patch montana western montana fall

Sweet Pickin's Pumpkin Patch in Kalispell is a popular destination for families looking to enjoy a fall day on the farm. Pick out your pumpkin, enjoy the seasonal atmosphere and make an afternoon of it.

It's also a great stop for families who want Halloween fun without necessarily looking for anything scary.

Explore the Conrad Mansion After Dark

For a Halloween experience rooted in local history, head to Kalispell's Conrad Mansion Museum.

The historic mansion has traditionally offered special October ghost tours, giving visitors the opportunity to explore the historic home while hearing stories about its past and its more mysterious side. haunted hauses in montana haunted hause missoula haunted house kalispell haunted house whitefish haunted house polson

Ghost tours have become one of the Flathead Valley's recurring Halloween-season attractions, so keep an eye on the 2027 schedule as October approaches.

If you're interested in history, architecture and a little paranormal intrigue, this is one Halloween experience worth adding to your itinerary.

Take a Haunted Hayride

For another classic Halloween experience, keep an eye out for the Clydesdale Outpost Haunted Hayride near Whitefish.

The attraction has featured an immersive haunted storyline, a hayride and midway-style entertainment. Past themes have included everything from creepy characters to an abandoned asylum storyline.

A haunted hayride is a great choice for groups looking for something more theatrical and immersive than a traditional haunted house.

Check the 2027 event schedule for the year's theme, dates and age recommendations before making plans.

Trunk or Treat in Lakeside

Looking for a fun, family-friendly way to celebrate Halloween right here in Lakeside? Head to Trunk or Treat, where local families and businesses come together to create a safe and festive Halloween experience for kids.

Held behind Lakeside Community Chapel on Adams Street, across from Lakeside Elementary School, the event invites kids and families to dress up, explore creatively decorated vehicles and, of course, collect plenty of Halloween candy. Trunk or Treat takes place on Halloween, October 31, from 4–6 p.m., and admission is completely free.

Costumes are encouraged, so come dressed up and ready for some Halloween fun! Whether you're looking for a low-key Halloween activity for younger kids or want to get out and enjoy the Lakeside community, Trunk or Treat is an easy addition to your Halloween plans.

Additionally, families visiting the town of Whitefish and Bigfork can enjoy downtown trick-or-treating as well. Local businesses throughout the towns have traditionally participated in Trick or Treat on the evening of October 31st, creating an easygoing Halloween experience for younger kids.

Enjoy Fall Around Flathead Lake

Halloween is only part of what makes October special in Northwest Montana.

The Flathead Valley is beautiful in the fall, with colorful foliage, crisp mornings and fewer crowds than you'll find during the peak summer season.

Spend the day exploring Bigfork, Lakeside, Somers, Kalispell or Whitefish. Take a scenic drive around Flathead Lake, grab a seasonal drink, explore local shops or get outside and enjoy the changing landscape.

And if you're looking for an adventure along the way, make a stop in Lakeside for a ride at Flathead Lake Alpine Coaster.

Plan Your 2027 Halloween Adventure

Whether you're looking for something family-friendly or you're ready to get seriously scared, the Flathead Valley has plenty of ways to celebrate Halloween.

From The Curse of Blackwater Mountain and the Zombie Trail to pumpkin patches, haunted hayrides, ghost tours and community trick-or-treating, October offers plenty of reasons to explore Northwest Montana.
