Lake Arthur and its sparkling waters are surrouned by gently rolling hills and lush forests in Moraine State Park. This is a very popular location with over one million boaters, hikers, bikers and swimmers visiting every year. The visitors however have helped environmentally restore the area from prior coal mining and oil and gas drilling. This is a large 3,225-acre lake, where canoeing is still very possible with so many visitors. Sailing is also popular here as conditions are ideal for the sport throughout the summer.
