Enjoy Halloween Safely Around Kalispell

With several events happening throughout the Flathead Valley, it’s worth planning your evening before heading out.

A few simple reminders can help make Halloween safer for everyone:

• Watch for pedestrians: Children will be walking between homes and businesses, often wearing costumes that limit visibility.
• Plan your route: Check event locations and schedules before leaving, especially if you’re attending activities in multiple communities.
• Make yourself visible: Reflective clothing, glow sticks, and flashlights can help children stay visible after sunset.
• Drive carefully: Slow down in residential neighborhoods and watch for children crossing streets.
• Check the weather: Late October in Montana can bring chilly temperatures, so dress appropriately for outdoor activities.

If you’re traveling between Kalispell, Whitefish, Bigfork, and other Flathead Valley communities, make sure your vehicle is ready for the drive.
