Both Nature and Bike Trail are open daily to the public for FREE from dawn until dusk. Nature Trail: The nature trail starts at the edge of the woods and winds down to the bottom of the property at Valley Street before returning to the top by another route. Thirty different species of trees native to Indiana are identified with educational signs. Other signs are written about non-native and invasive species, fruits of different trees, and other subjects The loop trail is about a mile long and feels very much like a wilderness experience in the middle of town. Bike Trail: The highly-rated mountain bike trail on the grounds is open to the public. It is a 6-mile out-and-back single-track trail with rocks, ledges, bridges, whoop-de-dos, benched areas, drop-offs, ramps, and other features. This is an intermediate trail, with some advanced loops that leave the main trail and return to the same place. Intermediate riders should enjoy the intermediate trail marked with blue arrows and may venture onto some of the advanced sections marked with red arrows. Helmets are required, and BMX bikes are not allowed. Part of the nature trail coincides with the mountain bike trail, and both riders and hikers must share the trail.
