Monster Ball
2026-10-31 19:00 - 22:00
Don your capes and shine your spooky shoes, the ball of the season will be underway this year at the Moss! Prepare yourselves for a Halloween night to remember with dancing, cocktails, a photobooth and more!

There will be three horrifyingly delicious cocktails on offer while you dance the night away to DJ Dan of Black-Tie Productions MT – he will be keeping this Monster Ball rocking through the night! The best monster costume will be awarded at 9:00 for all the competitive cosplayers out there!

Your reservation and payment of $55 includes admission to the mansion and grounds, specialized cocktails and appetizers to enjoy in one of our themed lounges (non-alcoholic options available too), as well as photobooth pictures and plenty of dancing. There will also be alcohol for purchase at our bar under the tent.

Know before you go: The festivities will begin at 7:00pm and will go until 10:00pm. You will need to report to the back of the Mansion upon arrival to check-in. Cocktails and appetizers will be inside where there will be themed lounges on different levels of the mansion, so be ready for plenty of stairs with sensible shoes. The dance floor will be under our large event tent outside.

Please bring a form of ID if you purchased a 21 and over ticket. Reservations are not eligible for a refund but may be transferred by calling 406-256-5100.
*Proceeds from Moss Mansion activities fund all daily operations and preservation work at the museum.*
