A grassy mound beside the A9 is all that's visible above ground, but there is a portion of a surrounding bank or defensive wall on the north side. There are plenty of broch sites in the area, and this one is in view of quite a few, including some of the Dunbeath brochs. Line of sight was obviously important for communication of some kind.
Turn in off the A9 north of Dunbeath onto a single track road and find parking near the broch that doesn't obstruct traffic. The broch is on private farmland with livestock, so let the farmer know what you're up to in case he's working with his animals and be sure to close the gate.

Disclaimer: Some brochs were built with military defensive purpose, and as such can be situated in extremely dangerous areas, such as on the edge of cliffs and ravines. Additionally, these are Iron Age structures, most of them in ruins, and they are extremely hazardous, with crumbling stone walls and hidden chambers. Existing walls, lintels, and passages could collapse at any time.
