This is a large area covering the sea-cracked western coast of Scotland from the foot of the Great Glen, south to the Mull of Kintyre and, all the way to its border with Fife, a huge diverse section of the interior. There are several distinctive areas; each of which is best explored as a single entity.

From Kinross and Tayside the A91 - A977 enters the eastern aspect of this region. Two intriguing names appear on local signposts, the "Rumbling Bridge" and the "Yetts o' Muckhart.' 'Yetts' means gates and applies to the entrance to the "Hillfoots", a long string of medium-sized elevations otherwise known as the Ochils.
