Trunks & Treasures
2026-03-08 16:30 - 18:30
Our most popular behind-the-scenes tour is back! Spend extra time exploring the mansion where regular tours don’t go with a seasoned Site Historian. Peek in drawers and other hidden spaces, read personal letters passed between members of the Moss family, look at interesting personal and business artifacts from the early 1900’s, and accompany your escort to the rarely-seen Ballroom on the third floor. We’ll show you more than we can share during a classic tour and give you time to ask questions and really dig deeper into the Moss family legacy.
Admission is $30 per person with a reservation at least three days in advance, limit 12 guests per tour.
You can also book a private Trunks & Treasures Tour – call 406-256-5100 and ask for Megan to find out how you can schedule this. At least three days in advance is required for a private tour.
