Spinsters' Rock is situated on Shilstone Farm west of Drewsteignton. It is near the A382 road. The dolmen consist of three granite supports rising to between 1.7 and 2.3 metres surmounted by a capstone measuring 4.5 by 3.1 metres. The dolmen collapsed in 1862 but was restored in the same year. No finds were recorded.
There are 18th-century antiquarian reports of nearby stone circles and alignments. These reports are considered to be of "dubious accuracy". There are some free-standing stones located nearby, although only two align with Spinsters' Rock.
