Whilst this is not technically a tor, there is a scattering of outcrop-type rocks near the Beacon casting a large clitter on the south-eastern slopes. The cairn itself acts as a conspicuous object from Plymouth, with a shelter, of sorts, positioned well for any south-westerly. The OS Surveyors clearly saw this as a striking viewpoint by erecting a trig point beside the highest point, at 429m, with the number '3427' inscribed onto the ruined flush bracket.
Eric Hemery (1983) is the first it seems to tell us of the rocks here; "The tor remnant is small indeed, being exceeded in size by a single huge rock on the south-east side of the summit, while the clitter, indicative of the bulk of the original rock-pile, is widespread upon the brow of the hill."
The area abounds in interesting artefacts, including a stone row at SX 59947 62553 cited immediately to the west of the reave that runs up to the Beacon from the south.
