Oriole Grove

Locally known as Jensen Woods, this 86-acre preserve straddles the Lake Forest–Lake Bluff border and connects two community natural areas.

Running along the length of the Skokie River, the preserve sits directly between Lake Bluff Open Lands Association’s (LBOLA) Skokie River Prairie to the north and Lake Forest Open Lands Association’s Skokie River Nature Preserve to the south. Visitors can access Oriole Grove from either of these two local natural areas.

Within Oriole Grove there are 1.35 miles of grass trails, making it a great place for hiking and cross-country skiing. Bikes are not permitted. Please keep dogs leashed and on trails at all times, and pick up after them. Learn about our off-leash Dog Parks (permit required).

Oriole Grove Master Plan Approved

More About This Preserve

The Natural Scene

The preserve includes an old growth oak-hickory woodland, which features a large grove of massive bur and white oaks estimated to be over 220 years old. There is also an oak-basswood woodland and two grassland areas with remnant and restored prairie, including “Birch Prairie.”

Jensen excavated the large kidney-shaped pond to match a smaller one next to Green Bay Road. The pond’s good water quality supports regionally uncommon fish.

The preserve serves as a keystone in a larger landscape of 240 acres of protected natural areas with Lake Bluff Open Lands, Lake Forest Open Lands and private landowners owning the rest. Approximately 40 acres are dedicated as State Nature Preserve status. 


The preserve was originally a private estate for rail magnate William V. Kelley, who purchased the property in the early 1900s from John Mines, an immigrant farmer from Ireland. Hired to design the landscape was Jens Jensen, one of the most significant landscape architects in Chicago history. He also designed the J. Ogden Armour estate, portions of which are now known as Middlefork Savanna Forest Preserve.
