This seasonal ferry is probably the oldest continuously operated ferry service in the United Stated. The ferry was started in 1655, to connect Rocky Hill and Glastonbury (which were formerly part of Wethersfield), as a raft that crossed the river using poles and oars. Over the years, power was added, first using a horse on a treadmill, then with steam and now with a diesel powered tug. Today’s “ferry” is a three to four car barge towed by tug boat. The ferry operates from May 1 through October 31, weather and river conditions permitting.
