Douglas is served by frequent ferries to/from England and occasional ferries to/from Ireland; the sole operator is the Isle of Man Steam Packet Company, with exclusive use of the Isle of Man Sea Terminal and the Douglas port linkspans under the conditions of the user agreement with
Port St Mary Railway between Douglas and Port Erin. Steam trains operate on the line several times a day during the summer season, and stop at Port St Mary. The village is served by Bus Vannin services to Port Erin, Castletown, Douglas and Onchan. Once a fishing and trading port, the village is still popular with tourists and fishermen, especially during the summer. The inner harbour, with its pier created in 1812, is tidal and dries out from half-tide. The outer harbour, created when the Alfred Pier was built in 1882, is accessible at all tide states - unique amongst the Manx ports.
