Tips for Visiting Natural Tunnel State Park#
- The park's overlook gives the best views of the natural railroad tunnel-plan to visit early or late in the day to avoid peak picnic/campground crowds and to get better light for photos.
- An incline railway that takes visitors down toward the tunnel floor operates seasonally; check the park office for current operating days and hours before you go.
- The tunnel is part of an active rail corridor, so trains are occasionally visible from the overlook-bring a binocular for a closer look and time your visit if you want to watch rail traffic.
