Go old school with a nice family picnic at one of the 60 picnic sites, equipped with barbecue grills, tables, and play areas. For larger groups, there are 3 big spaces which can be reserved in advance.
Head to the 65-acre Clarkco Lake and enjoy a peaceful afternoon of fishing. If you are feeling more adventurous, water skiing is an excellent option.
No outing with kids is complete without a playground, and Clarkco State Park understands this well. Let your children have fun at the park's slides or play a game of tag on the picturesque waterfront.
Challenge your friends to a game of tennis at the lighted courts, or go disc golfing at the nine-hole disc course. The park also has softball and baseball diamonds and a basketball court.
