B873 is a very scenic drive in the Highland region of northern Scotland. The road runs alongside Loch Naver.
The road is pretty narrow. It’s asphalted and links Altnaharra and Syre on the very shores of Loch Naver. B873 is 11.4 miles long. It’s a single track road, where you hardly ever meet another vehicle. It’s a desolate road fairly flat. There are some narrow sections -scarcely wide enough for two cars- where if two vehicles have to pass each other, one might have to reverse for some kilometers of winding narrow road to get to a place wide enough to pass. It shouldn’t be attempted by those who don't know how to reverse.
