The Holiday Inn Spearfish Convention Center is in the perfect location with all your necessities and local attractions nearby. Our hotel shuttle will take you to downtown Spearfish for an afternoon of local shopping and restaurants. Experience the best of South Dakota's Craft Beer scene with our local breweries; each with their own distinct brand and flavors. Outdoor enthusiasts love to explore DC Booth Historic Fish Hatchery, snowmobile in Black Hills National Forest or ski at Terry Peak. With convenient access to Interstate 90, it is easy to navigate to destinations all over the Black Hills. Day trips to Mount Rushmore and Crazy Horse Memorial are guest favorites, as is visiting the mysterious Devils Tower.
