Earth Day is this weekend, I hope you will consider attending an event on Saturday April 21st at one of our previous article on Earth Day events at our state parks).
Taking a walk from the cabin area at Natural Tunnel State Park(Park map here)
Walking a trail to the river at Natural Tunnel State Park
You know the saying "Take the stairs, not the elevator"
You can still enjoy the chair lift (going down to the tunnel and back after your walk!)
