Keystone's Hometown Celebration

Keystone residents have always loved getting together to have a good time. For over 100 years, we did just that at the annual Holy Terror Days. Originally an Independence Day celebration, Holy Terror Days eventually turned into an event celebrating Keystone, and moved to September. After 2017’s celebration, however, the event was discontinued.

It didn’t take long until city leaders in Keystone decided to bring back a fall celebration. They wanted to create a celebration that focuses on the unique history and community of Keystone, from our earliest days to our modern triumphs. After lots of thought and hard work, in 2020, Keystone’s Hometown Celebration was born! 

Our Hometown Celebration welcomes locals and visitors alike to our historic town. Join us for an old-time event featuring a carnival, community BBQ, historical reenactments, and a costume contest where you can dress up in your best 1890s garb. It’s a great reason to get out of the house and enjoy the best of the beautiful Black Hills in the fall, and we think you’ll agree that the Hometown Celebration lives up to our motto, “small town, big spirit.”

Keystone is the perfect place to base your family vacation, and our Hometown Celebration is a can’t-miss event you’ll want to plan for. Mark you calendars for September 17-18, 2021, and we look forward to seeing you there!
