Montana's 2026 Halloween Guide: Haunted Attractions, Costume Parties, and Everything In Between
Updated: 52 minutes ago
Halloween in Montana goes well beyond trick-or-treating on your own street. Deer Lodge has a haunted prison. Whitefish runs a haunted horse-drawn hayride. Across the state, October brings corn maze haunts, candlelit ghost tours, costume bar crawls, and family-friendly trunk-or-treats. This guide can help you narrow down what to do this October, organized by the kind of scare, or non-scare, you're after.
