The Colchester Causeway is a popular, incredibly unique recreational trail located in Burlington, Vermont. It extends from the mainland to South Hero Island in Lake Champlain. The causeway is a narrow strip of land that was once used by the Rutland Railroad as a rail line connecting Burlington to the Champlain Islands. However, the rail line was abandoned in the 1960s, and the causeway was converted into a trail for pedestrians and cyclists. The causeway offers stunning views of Lake Champlain and the surrounding mountains. It's a popular spot for walking, jogging, biking, fishing, and birdwatching. The trail is relatively flat and easy to navigate, making it suitable for people of all ages and fitness levels. One of the highlights of the Colchester Causeway is the scenic bike ferry that operates during the warmer months (check the schedule here https://www.localmotion.org/bike_ferry). The ferry shuttles cyclists across a 200-foot gap in the causeway, allowing them to continue their journey uninterrupted. This unique feature adds to the charm of the trail and provides a memorable experience for visitors.
