From the EH Record of Scheduled Monuments:
Bummers Hill bowl barrow is situated on the north end of a prominent ridge overlooking the River Quin. The monument includes an earthen mound which measures 24m in diameter and 2.82m in maximum height. Although no longer visible at ground level, a ditch, from which material was quarried during the construction of the monument, surrounds the mound. This has become infilled over the years but survives as a buried feature c.3m wide.
