About
Overview
Oak Grove Picnic Area is a day-use facility located on the 26,000-acre Saylorville Lake Project, which stretches over 50 miles up the Des Moines River Valley. The lake provides a wide variety of recreational activities, including boating, swimming, fishing, hiking and hunting.
Recreation
Visitors come to Saylorville Lake for its great boating, sailing, water skiing, windsurfing and swimming opportunities. Anglers fish for walleye, wiper, largemouth bass, catfish, crappie and northern pike.
The paved Neal Smith Trail winds 24 miles from Des Moines to Big Creek State Park and connects the campgrounds on the east side of the lake. It is designated as a National Recreation Trail and is used for biking, hiking, jogging, walking and in-line skating.
Facilities
This day-use area offers two group picnic shelters with electric and water hookups. Amenities include flush toilets, a playground, volleyball court and hiking trails.
Natural Features
Oak Grove lies among a heavily wooded forest of stately oak trees on the east side of the lake. A large beach is within walking distance.
Wildlife is abundant throughout the project. White-tailed deer, turkeys, pheasants, waterfowl, and other small game animals roam the lands around the lake.

Is OAK GROVE PICNIC AREA fully booked?
A campground showing no availability is almost never full for good. People cancel — plans change, weather turns, someone books three weekends and keeps one — and the site goes straight back into the booking system, usually without warning and often at odd hours. The reason sold-out campgrounds feel impossible is not that sites never free up; it is that nobody is watching at the moment they do.
