MHSP program location flag by Mary Colwe

Walk With a Naturalist:  Ages 5 and up. Walks are limited to 10 people, including the leader. Walk-ins are welcome if space allows.

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? What about those animal tracks in the snow? 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 60-90 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 sunglasses, sunscreen, a hat, water, comfy shoes, and bug spray. Hike times begin at 10:00 a.m. Let's go!
