Sully (Welsh: Sili) is a village in the Vale of Glamorgan.
Cardiff Bus's 94 bus runs twice an hour each way between Cardiff and Barry. Sprint Transport also run the 88 bus once an hour in each direction between Barry and Penarth, stopping at Penarth Esplanade for the pier, walks on the shale beach and ice cream. Tickets on the two services are not interchangeable.
Sully Island is only accessible on foot from three hours before until three hours after low tide. Remember to come back before the tide comes back in otherwise you will be stuck for 6 hours! In no event try to cross if the rising water is cutting you off - tides off this part of the Glamorgan coast are some of the highest in the world, many people have been swept to their deaths while trying to leave the island as the tide rises very rapidly.
