Love this place. We usually go twice a year. The park is big with a number of picnic tables, but it does get busy on holiday weekends so bring blankets for a picnic just in case all tables are full. They have a marina, a restaurant, a hotel, and campsites around the lake, and it's right outside Carlyle IL so if you forget anything or prefer not to pack a picnic, there's a grocery and a couple restaurants in town too. There is a nice sand beach close to the marina, and they don't allow glass on the beach either, so you can go barefoot if you like.
