The best feature of this park, in my opinion, is the four-mile paved recreation trail that goes around the entire 171-acre lake. Good for walking, running, or biking. The lake is beautiful, and we also saw people boating, kayaking, and fishing. Although swimming is also allowed, the beach was not the best for this activity.
The campsites are a little too close together for our liking, however, many are shaded and have a direct view of the lake. Full hookup, electrical, and primitive sites are available. We were there on a Sunday in August and the dumpster was overflowing, likely due to a large weekend crowd; I would expect that it would be emptied on Monday.
Lake Anita is a very nice state park about an hour west of Des Moines. There are also several picnic shelters located throughout the park and a nice playground centrally located in the playground.
