Woldumar Nature Center in Lansing, Michigan offers over 5 miles of hiking and cross-country skiing trails along the banks of the Grand River.

Woldumar Nature Center was the result of the efforts of the Woldumar Nature Association, who formed in the mid ’60’s to develop a conservation education program for young people. Gladys Olds Anderson, daughter of automotive pioneer Ransom Eli Olds, donated half of her dairy farm land to the association and Woldumar Nature Center was born.
