The B9136 runs along Strath Avon in west Banffshire. The road was originally unclassified but had gained its number by 1932.
The road starts next to the Bridge of Avon on the A939 a little north west of Tomintoul. The first 100 m or so are the original route of the A939, before the new bridge was built over the river, but on reaching a turn for the old bridge we arrive at the original southern end of the B9136. We stay on the eastern bank of the River Avon for the whole route, twisting and turning along the tortuous contours of Strath Avon, although rarely dropping that close to the river, and never passing through anywhere that could really be called a village.
The scenery, however, is stunning. This whole upland area south of Strathspey is a beautiful part of the country, and Strath Avon doesn't disappoint. As we steadily drop downstream, the road seems to climb more than fall, and whilst we drop about 100 m, most of that is in the first few miles.
Halfway down, a turning to the left leads across Silver Bridge to the western bank of the river, but we keep heading north, passing the distinctive and recently painted miles, the original route of the B9136, drops down to Drumin Castle, while we turn up Glen Livet a little to cross the Livet at Bridge of Livet, meeting the B9008 on the far side.
