Woldumar Nature Center grew out of the estate R.E. Olds built for his daughter

The strange name on the sign — Woldumar — was a wedding gift of sorts. Ransom E. Olds, the man behind both Oldsmobile and the REO Motor Car Company, built a riverside estate in 1930 for his daughter Gladys Olds Anderson, and the made-up name stuck to the land. Today it covers more than 180 acres of forest, prairie, pine plantation, and wetland along the Grand River, a few minutes west of downtown Lansing, with over five miles of trail running through all of it.

Gladys gave the heart of the property — about 120 acres — for a natural-science camp in 1966, and it grew into the nature center that’s there now. The grounds collect a few pieces of Lansing’s past the way a riverbank collects driftwood. There’s the old Olds-Anderson Rotary barn, restored and rented out for events. And there’s the Moon Log Cabin: the boyhood home of Darius Moon, the architect who designed a long list of grand Lansing houses, hauled here in 1980 and rebuilt log by log so it wouldn’t be lost.

The trails do the real work. They drop off the higher ground down toward the river, through pine rows planted in tidy lines and stands of older hardwood, past prairie that hums with insects in late summer. The visitor center keeps live animals and rocks to handle, and the staff run the kind of weekend programs that send kids home muddy and happy. You can reach the place straight off the interstate, which makes the quiet on the trails feel almost unfair.

Walk down to the Grand on a still morning and you’re standing on ground a car magnate once gave his daughter, now grown back into woods.
