Walk With a Naturalist:  Ages 5 and up.

Ever wonder what that animal call was, or which bird flew past? What's the name of that beautiful flower with the spring-loaded seed pods? And how much food can chipmunks cram in those cheeks? Our naturalists can fill you in about the crazy, fantastic, weird and amazing natural world we live in as we walk along the trails. Fall and winter walks are usually turn-around hikes (out & back) for 90 minutes. From April through early fall, we can be on an adventure from 10:00-12:00.  If it's hot, we'll finish earlier. Remember to dress for the weather. Other items to keep you comfortable are sunscreen, a hat, water, comfy shoes, and bug spray. Let's go!

Meet naturalist Mary at the Park Office lot. We'll explore the aquatic realm of Lake Defiance - a high quality glacial lake! This lake harbors more than meets the eye, from carnivorous bladderwort plants to diving beetles, turtles, frogs & fish. Life vests are required to be WORN for the entirety of the adventure. Bring your own boat, and be proficient in its use.

          *If the lot is full, you can unload your boat at the office, zip over to the neighboring Lake Defiance parking lot to park your vehicle, and walk back to us within 5 minutes.
