Achorn broch is hardly recognisable as such, being a grassy mound with much of the ruin plundered of stone. However, there is a small trench dug into the mound revealing a section of original wall, which is most probably a section of mural gallery.
There is no public access to the site. With permission, there is easy access and you can park off the single track road beside the nearby cattle grid. Remember to leave access to the gate by the cattle grid free so farmers can drive their animals should they need to.

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. The information here is provided free but it is your responsibility to ensure its accuracy, ensure your own safety, and acquire permissions for access where necessary. Accessing brochs is done entirely at your own risk.
