Fees
Peak season (May 1-Oct 15) rates per night: sewer/water/electric sites $34/night, electric sites $22/night. Rates include sales tax. A $4/night equestrian fee is bundled into equestrian-campground rates above where applicable (except youth group sites). A $4-$5/night surcharge applies on Memorial Day, Labor Day and July 4th holiday weekends. Off-season (Oct 16-Apr 30) rates run roughly $2-6/night lower than these May 1-Oct 15 peak-season rates for the same site type. (Iowa DNR's own official per-park camping rate schedule, iowadnr.gov, updated February 15, 2026.) Pets are allowed in Iowa state park campgrounds, subject to Iowa DNR's park regulations: "Pets shall not be left unattended in campgrounds" and "Privately owned animals shall be kept on a leash with a maximum length of six feet, or be kept confined." (iowadnr.gov's own park-use regulations.)
