Spooky Nook Sports & Champion Mill Conference Center

About Us

Opened in early 2022, our 1 million square foot facility highlights a dramatic re-imagining of the historic Champion Paper Company site, originally built in 1893. Spanning both sides of North B Street, our complex represents a new destination in Butler County and southwest Ohio, and offers interesting opportunities to stay, play, meet, and dine.

“Mill 1” houses North America’s largest indoor sports complex, with 690,000 feet of sports and activity surfaces. Our hardwood courts and multi-sport surfaces can host large tournaments of most any sport (max 28 basketball or 46 volleyball courts), leagues, and private events such as a trade show, expo, or large dinner. Mill 1 also features a 65,000-foot fitness center, with state-of-the-art equipment and many amenities. Our full-sized outdoor turf field can host a variety of sports - day or night. Mill 1 also includes a large food concessions area, smoothie bar, beer garden, mezzanine viewing areas, and video arcade.

“Mill 2” is a 3-story building spanning 600,000 square feet and houses our hotel, conference center, restaurant, bar, microbrewery and specialty retail. The Warehouse Hotel features 233 architecturally interesting guest rooms. Just off the hotel lobby is our Hydraulic Bar, a family-friendly, casual dining experience with delicious drinks, shareables, flatbreads, and more. Just up the grand staircase, the Champion Mill Conference Center occupies the 2nd and 3rd floors, with 16 meeting and banquet rooms to host up to 1000 guests.
