Castle Semple Loch was part of the historic Lochwinnoch estate. It was a fishing loch and part of the wider drainage scheme that the estate owners created to improve the local land for farming. Today the loch is still used for fishing and water sports. There is a RSPB bird sanctuary along the southern shore and a network of paths and trails that are popular with families, cyclists and dog walkers in the wider Castle Semple Country Park to the north.

Start at either Loch Thom / Greenock Cut Visitor Centre or at Overton Road, Greenock where there is both ample parking. Decent quality circular route with slight undulations that aren't too strenuous.

Lovely smooth tarmac from the main road, then some undulating gravel past the lochs before rejoining a lovely single track road.
