Castle Semple Loch is a 1.5 mile long inland loch at Lochwinnoch in Renfrewshire, Scotland. Along with the neighbouring Barr Loch, Castle Semple Loch lies in an area previously covered by one large loch known as ‘Loch Winnoch’, however by the end of the 18th century silt from the River Calder had divided the loch into two and Castle Semple and Barr Loch became separate entities.
Previously part of the Castle Semple Estate, the loch now comprises part of the Clyde Muirshiel Regional Park and the neighbouring Castle Semple Visitor Centre has a cafe and small shop. The Regional Park run a Ranger Service and Watersports Centre at the loch and run a variety of events and courses throughout the year.
We also share the loch with Castle Semple Rowing Club and although with a number of different water users the loch can get get quite busy, we are very good at keeping out of each other’s way (dinghies racing have priority!).
We have plenty of space for launching and next to our compact clubhouse (there are plans afoot for a larger facility shared with the Rowing Club) we have a large secured boat park.
There’s plenty of car parking at the Visitor Centre.
