Tenhave Leaf Scavenger Hunt is good way to encourage you and your children to visit Tenhave Woods.  Click on to the following link where 6 different leaves are shown and can be found lying on the ground in the park.  Good hunting! 


Tree First has installed a QR code sign on the fence just outside the Tenhave Lexington Entrance.  There are also 4 QR code signs attached to 4-inch square posts located along the Sandbar Trail (west side) with the last one being located just beyond the large oak in the center of the park.  If you are in Tenhave sometime, you might want to check them out.  



WHO ARE WE: The Royal Oak Nature Society is a volunteer group working with the City of Royal Oak to protect, maintain and promote the usage of Royal Oak's two nature preserves, Cummingston Park and Tenhave Woods.  We are also in the process of developing an arboretum and wildflower garden (Royal Oak Arboretum) behind the Royal Oak Senior Center (3500 Marais).  Go to the Nature Society page to learn more about us. 

ABOUT OUR PARKS: Both Cummingston Park and Tenhave Woods are nature preserves that are over 20 acres in size and are heavily wooded with lined trails.  They are designated by the city of Royal Oak as conservancy parks where the protection and management of the animal and plant/tree life in the parks is the primary concern.  They are open daily to the public from dawn to dusk.  Click here to find out why dogs are not allowed inside either nature preserve.  Go to Nature Preserves page to learn more about Cummingston Park and Tenhave Woods. 

The Royal Oak Arboretum is a park located behind the Senior Center.  It has been under development since 2007.  The long range plan for our arboretum is to create a collection of native trees/plants that are not found in Tenhave Woods.  Link on to Royal Oak Arboretum to learn about its history and progress. 

ADDITIONAL INFORMATION:  To find out where these parks are located on a map and a map of their trail systems, click here.  Wearing boots while in the parks is recommended during the winter and spring months. Using insect repellent and dressing appropriately is advised from late spring through the end of summer.  To learn more about these parks firsthand, check out our Naturalist Led Nature Walks schedule.

Land History

Behind the natural beauty of Tenhave Woods and Cummingston Park, there is a land history to explore. Please check out these links to Tenhave Woods (PDF) and Cummingston Park (PDF) to learn about the people who once lived on these lands.

The Goodwin family was the first owner of the land that now includes Tenhave Woods and Royal Oak High School. The below photo is of Samuel Volney Goodwin's family and farmhouse during the middle 1880s. Samuel was the third generation of Goodwins to own this piece of land.  The house was located just south of Normandy Rd. & just east of Crooks.
