The Mystic Depot Welcome Center is home to the Greater Mystic Chamber of Commerce and the downtown Mystic train station.
The Chamber owns and operates the center and provides visitor information such as maps, and local guides. During business hours Chamber staff and volunteers answer questions about the area and also provide train times and tickets for the train. An ATM is located inside.
From May to October the Mystic Depot is also home to one of the locations of Mystic Community Bikes, which for a $10 refundable fee allows visitors and locals alike to rent a bike.
