This beautiful station and pier bring back many memories for me, although we never took a ferry from here! (That came much later with my first wonderful trip across to Rothesay). We just used to drive down here from Greenock to have a walk and to admire the glorious architecture and all the floral displays which used to adorn the concourse and facade in the spring and summer months. Sadly, I don't think it is ever decorated in that way these days. My photos are from 2008.
The Undiscovered Scotland page about this station does it far more justice than my photos - you can see it here. The Wemyss Bay website here is also very interesting with more about the history of the station.
