Big Creek State Park

Located near Saylorville Lake just 20 miles from Des Moines, Big Creek State Park is a family-friendly setting for picnicking and outdoor recreation. The centerpiece is Big Creek Lake, home of the largest beach in the state park system. The lake is also a popular fishing destination with boat and bike rentals available at the beach concessionaire. Take a day-trip to Big Creek State Park this season and enjoy everything Iowa outdoors has to offer.


Hike or bike along the paved, 27-mile Neil Smith Trail, which leads from the beach through the Saylorville Lake area, all the way to Des Moines. In the winter, cross country ski on a 3.5 mile trail on the disk golf course.

Swim in Big Creek’s lake and soak up the sun on the beach during hot summer months. Boating is also a popular lake activity, with kayaks, paddle boards, pontoon boats and bikes available to rent at the beach concessionaire. Please contact the concessionaire at 515-984-6083 or for more information.

Fish among the coves on Big Creek Lake, a hotspot for crappie, walleye and bluegill. Big Creek has five boat ramps, several fishing jetties, an accessible fishing pier and miles of shoreline.
