Calkins Nature Center & Area

Just minutes from Iowa Falls, Calkins Nature Area is one of Hardin County’s hidden gems, offering 76 acres of scenic woodlands, rolling hills, and riverfront beauty to explore. With more than three miles of hiking trails, a beautiful nature center, and free admission, it’s the perfect stop for families, outdoor enthusiasts, and anyone looking to slow down and connect with nature.

Inside the 6,000-square-foot Calkins Nature Center, you’ll discover exhibits highlighting the area’s natural and cultural history, including one of central Iowa’s largest collections of Native American artifacts. Outside, visitors can wander through a butterfly house filled with native flowers, explore a Native American tipi and foraging garden, watch wildlife in the live animal exhibits, stroll through the educational rain garden, or enjoy a picnic overlooking the Iowa River. During the winter months, cross-country ski trails and rentals make it a year-round destination.

Whether you’re hiking the trails, learning something new in the museum, or watching Monarch butterflies flutter through Shirley’s Butterfly House in mid-summer, Calkins Nature Area offers an unforgettable outdoor experience that’s well worth adding to your Iowa Falls itinerary.
