The Moraine State Park Regatta (formerly called Regatta at Lake Arthur) is an annual 2-day regional event celebrated on Moraine State Park's South Shore the first weekend in August. We are excited to welcome you, your family, and your friends to come and see all that the Regatta has to offer.
There is no admission or parking charge and many Regatta events are FREE.
This annual event brings thousands of visitors each year to experience and enjoy the 3,225 acres of Lake Arthur with over 40 miles of scenic shoreline. The Regatta offers land and lake activities along with exciting new opportunities to enjoy the natural resources of the park (with recent years averaging 15,000 - 20,000 visitors). Our mission is to be the premiere, all-ages, eco-recreational event in the region. While we are nestled in the heart of Butler County, we welcome visitors from across the region and beyond. If you enjoy being active in the great outdoors, then this is a weekend you simply don't want to miss! We are excited to continue to promote a healthy lifestyle, feature wholesome food options and continue to increase opportunities for you to get out and active at Moraine. Plans for the next will include exciting additions! If you are interested in getting involved with the Regatta through leadership, sponsorship, or offering a great idea for us to consider, please contact us. Come on out and PLAY!
