The boat trip took us there and back to the island of Inchcolm on the estuary. It is a very small island and the main feature is this former Augustinian Abbey. Although the island is inhabited the ferry service does stop to let people off and then pick them up an hour later. We chose not to get off although I would like to have seen more of this fascinating island. As the ferry continued back to South Queensferry. The total round trip took just over an hour and a half and was well worth the time and effort - I would definitely recommend it.
