Bridge of Orchy Hills
The Bridge of Orchy Hills are a range of soaring hills in the west of Perthshire and the northeast of Argyllshire. They rise to the east of Bridge of Orchy, from which they are named, and at the head of Loch Lyon, to the north of Loch Lyon. The watershed between the east and west coasts of the land runs along the main ridge of these hills, north to south, and marks the boundary between the counties of Argyll and Perth.
South of these hills, across Loch Lyon, are the Mamlorn Hills, and to the east, ranged around Glen Lyon are the Glen Lyon Hills.
There are five munros in these hills, all but one on the boundary of the two shires apart from Beinn Mhanach, faithful to Perthshire alone. The munros are:
| Beinn a' Chreachain | 3,547 feet | 1,081 m | NN373440 |
| Beinn Dorain | 3,530 feet | 1,076 m | NN325378 |
| Beinn Achaladair | 3,405 feet | 1,038 m | NN346433 |
| Beinn an Dothaidh | 3,294 feet | 1,004 m | NN331408 |
| Beinn Mhanach | 3,130 feet | 954 m | NN373411 |
