The three main hiking trails in Mallows Bay Park are the Nature Loop, the Beaver Trail, and the Ridge Trail. They can be completed one at a time or hiked all together on about a 2-mile loop. Each trail ranges in difficulty from easy to moderate and offers many plants, wildlife, and habitat types. These trails move between forests and wetlands and offer photos and videos of the plants, animals, and fungi that live there.  You can even see some changes among the different seasons in the beautiful Mallows Bay Park.
