Crystal Lake State Park, run locally as Crystal Lake Park, is an Iowa state park on the east side of Crystal Lake in Hancock County, managed by the Hancock County Conservation Board. The park pairs a reservable lakeside campground with a set of year-round cabins and a 264-acre lake where the Iowa DNR reports a crappie population in good condition and strong northern pike numbers.
Who Runs Crystal Lake
The Iowa DNR lists Crystal Lake among the “state parks managed by other entities” in its 2026 state park guide, with the Hancock County Conservation Board as operator. The board’s office is at (641) 923-2720; Travel Iowa lists (641) 924-2186 for the park itself.
Camping and Cabins
Crystal Lake Park has 29 reservable electric campsites, and all reservations are made on Hancock County’s page on mycountyparks.com (as of October 2026). Iowa’s state park reservation system does not cover this park. You may use a reservable site that has not been booked, but the county asks you to pay for only one night at a time, check the site marker daily and move if the site becomes reserved. A walk-in site counts as occupied only with a camper, tent, car or trailer on it in addition to the paid registration tag.
The county also rents cabins half a mile north of the town of Crystal Lake. According to Travel Iowa, they come with a deck, fire ring, parking, air conditioning, heat and basic cleaning and cooking supplies, and Cabin 1 is accessible. Bring your own pillows, bedding, towels and firewood; firewood is sold in the campground north of the cabins. Travel Iowa lists the campground as open from May 1 to October 15 and the cabins as open year-round, but its listing has not been updated in the last 12 months, so confirm dates with the county.
On the Water
Crystal Lake covers 264 surface acres with a maximum depth of 18.6 feet (Iowa DNR, 2021) and no motor restrictions. The DNR lists a hard-surface boat ramp, a fishing jetty, a beach, trails, a playground, restrooms, accessible shoreline and a fish cleaning station.
The DNR’s fishing summary rates the crappie population as in good condition: fish the spring spawn along the shoreline, or drift and troll small jigs in the middle of the lake in summer and fall. Northern pike numbers are strong, with some larger fish, the largemouth bass population has improved around shoreline structure, and bluegill size is rising, though you will still sort through smaller fish. In its October 1, 2026 report, the DNR rated crappie and bluegill fishing as good.
Getting There
Travel Iowa lists the park at 1045 320th St., Forest City, Iowa; the DNR’s county park list places it on the east side of Crystal Lake.
