The second course at Turnberry, the Kintyre, is a fine one in its own right yet is often overlooked by golfers heading to this part of the world.
Clearly any course that plays second fiddle to the Ailsa may go under the radar but I would strongly suggest a play at this demanding links if time permits.
The greens are modern in design, have greater undulations than the main course and your ball is more likely to kick-off one of the humps and mounds at the green edges into swales and hollows around the putting surfaces.
Gorse is also a threat on many of the holes.
EDIT: The Kintyre has been completely remodelled and is now open as the 'King Robert The Bruce' course.
