Ohio Birding Day Hike
Caldwell Nature Preserve Trails
This is a hidden gem that offers a 2.7-mile loop trail through natural areas with mature walnut, oak, and beech trees. Pass over bridges and through gorges as you follow the trail on the ridges formed long ago by the Mill Creek Watershed. There is also a level paved trail that is handicap accessible and plenty of wildlife to be seen.

Park at the nature center. There are not specific trails in Caldwell Nature Preserve, but rather a network of trails going all over the park. The trail system will take you through mixtures of Old Growth forest and recently planted trees and through small stream valleys.
