1966 Hiking Challenge: Harbor Belt

1966 Harbor Belt Trail Banner

With a unique pattern of alternating sand ridges and lush wetlands, Miller Woods is an enchanting landscape of diversity. Delight your senses as you travel through this globally-rare topography known as ridge and swale on the Harbor Belt. The Harbor Belt is an abandoned railroad bed that cuts east-west through Miller Woods. Catch the crimson shimmer of a red-headed woodpecker on a black oak as you explore deep into Miller Woods.

The 1966 Hiking Challenge is comprised of 19 hikes that cover 66 miles of trail in the park- celebrating the park’s founding in 1966. The ranger-led hike for this trail met at the Paul H. Douglas Center's parking lot and was scheduled for Saturday, July 13th at 8:00 AM. Do not worry if you cannot make each of the 19 ranger-led hikes. A check-off sheet will be available at the Visitor Center or the the Paul H. Douglas Center for those who complete the hikes on their own.
