For ten years, the Big Sky community has come together to celebrate Halloween with costumes, music, family activities, spooky adventures, and plenty of mountain-town fun. This year, we’re celebrating a decade of Haunted Peaks with a full weekend of events for all ages.

From the annual Costume Climb and Community Trunk or Treat on Friday, to a Halloween Fun Run, Costume Parade, Block Party, and Haunted House on Saturday, the weekend wraps up Sunday with a beautiful community celebration of Día de Muertos.

Whether you’re looking for family-friendly fun, a little friendly fright, live music, a costume contest, or simply a great excuse to celebrate with friends and neighbors, there’s something waiting for you at the 10th Annual Haunted Peaks Festival.

Gather your crew, grab your costumes, and join us October 30 – November 1 for three unforgettable days of Halloween in Big Sky!
