Discover the rich history of the Little Miami Valley at East Fork. With evidence of human activity dating back 3,000 years and an Adena-built mound nearby, the park is a captivating journey through time. Explore diverse landscapes with hiking and multi-use trails, then venture onto Harsha Lake, a vibrant, unlimited horsepower waterway hosting regional and national rowing events. Beyond water activities, enjoy pickleball, cornhole, ping pong, volleyball, soccer goals, and even putt-putt golf—a perfect blend of history and recreation. East Fork boasts the most hiking miles in the State Park system, the longest consecutive trail (Perimeter Trail-33 miles), and the biggest dam in Ohio.
