About Turin Wildlife Management Area

The Monona County Conservation Board and Iowa DNR partnered with the Iowa Natural Heritage Foundation to acquire 280 acres from the Reese family — land they had owned since 1856. Overlooking the Missouri River valley from the Loess Hills, the Turin Wildlife Management Area was once a bed-and-breakfast and is now part of the Loess Hills Bird Conservation Area, a key migration corridor for raptors, shorebirds, and songbirds. It also provides critical habitat for species like bullsnakes, fox snakes, six-lined racerunners, and the hognose snake, a species of greatest conservation need.

 

Directions from Onawa— Follow IA-175 east for 7.1 miles to Turin. Turn left onto Oak Ave on the east side of Turin. Continue for three miles and turn left onto 210th Street. The destination will be on your left. Look for LHPS signs.

  

Stick around after GRASS for the Loess Hills Prairie Seminar. Participate in just one session, the entire day, or stay the whole weekend. Camping is available as well as hotel, area Airbnbs, and a few county-run cabins.
