Visited in freezing temperatures (1.2.09). The largest barrow is impressive, pretty much as per the dimensions quoted by L.V. Grinsell (see Misc). The hollow in the top is clearly visible. One of the smaller barrows was apparent to the NE, but I couldn't see the SW barrow as reported by W.L. Cox.
The barrows are situated in a small clump of trees adjoining the east side of the A417, which is incredibly busy. Access is from the Gloucestershire Way, which runs through the trees to the SW of the barrows. The path hits the road directly opposite the carpark of the Air Balloon pub (also worth a visit!).
Well worth a visit during the autumn/winter, but I imagine that the barrow will be lost in foliage and vegetation in the summer. Could easily be incorporated in a visit to Crickley Hill (as I did today).
Info about the site from "Gloucestershire Barrows" - H. O'Neil and L.V.Grinsell (1960) Transactions of the Bristol and Gloucestershire Arch. Soc., listing three barrows, the largest of which, based on 1959 measurements, is 12ft high from W, 6ft high from E. On top is a hollow 10 yards diameter and 3.5 ft deep. The mound is surrounded by a ditch 11ft wide and 3.5 ft deep and there are slight indications of an outer bank.
In 1981, W.L. Cox ("Prehistoric and Roman Sites of the Cheltenham area" (1981 2nd ed)) recorded the site as:
"One large round barrow and the remains of a small one, the latter being difficult to see SW of the former. They are situated in a small plantation alongside the B4070 from the Air Balloon to Birdlip and opposite the entrance to the car park of the Inn. The large mound is taller (12ft) from the west, than the east (6ft), owing to the slope of the ground.
Without investigation it is difficult to date these mounds but the siting below the ridge would suggest a Bronze Age date 3000 years old"
In 1987, a "clandestine hole" was dug into the largest barrow, revealing a "limestone cairn structure" (Gloucestershire Barrows: supplement 1961 - 1988" - T.C.Darvill and L.V. Grinsell (1989) Trans of the Bristol and Gloucestershire Arch. Soc.
