Meet the Residents

Visit the nature center and speak to a naturalist to learn more about the wildlife that lives in the surrounding natural areas. Meet a few of our nature center resident reptiles in the wildlife room. 

Outdoor Play

Our natural playground features climbing rocks, Carol's Cabin, logs and a native plant garden.

Hike the Trails

The hiking trail loops are organized by the type of natural community they pass through and are marked with color-coded wooden posts. Unmarked connector trails help to link these loops to each other and to other parts of Whitnall Park. Note: the trails at Wehr are for walkers only. No runners, cycling or dogs.

Nature Programing

Nature programing for children, groups and adults is held throughout the year. Most programs are organized by the Friends of Wehr. These programs encourage discovery and curiosity and help everyone build a personal connection to nature.

Summer camps for children ages 6 to 12 let children discover the natural world, make new friends and gain confidence as they learn new skills and take on outdoor adventures. Camps are led by professional naturalists who nurture each child’s natural sense of wonder.
