This article is about the current B873 through Strathnaver.
For the former B873 (now A9) from Latheron to Georgemas Junction near Halkirk, see B873 (Latheron - Thurso)
The B873 starts on the A836 just north of Altnaharra, at first running through a small forestry plantation before dropping down to the shore of Loch Naver. As it heads west along the loch there are often stunning views in both directions. After about 7 miles, the end of the loch is reached, and the road swings round to the north into Strathnaver proper, passing the occasional farm until the tiny settlement of Syre is reached. Just past the tin church, the road ends at a TOTSO with the B871, which continues north to the A836 near Bettyhill.
