Each year, Woldumar Nature Center – a private, non-profit organization — attracts some 40,000 visitors from across mid-Michigan. Situated along the Grand River with 1.25 miles of shoreline, Woldumar represents one of the most diverse ecosystems in the region. More than 5 miles of trails await you on 150 acres of woodland, prairie, river-side and pine forest! Hike or ski anytime between dawn and dusk. We offer numerous outreach and on-site Environmental Education programs for children as well as adults. The Visitors Center is a great place to start with interpretive and live creature displays!
