Eight metres wide and oriented roughly north-north-west to south-south-east, it is known on older Cassini editions of the Ordnance Survey maps as Cladh na Leac, a name suggesting a flagged or stony way. What is quietly extraordinary about it is not simply its age or length, but its invisibility in the documentary record: neither the 1840 six-inch nor the 1897 twenty-five-inch Ordnance Survey maps record it as a road at all, only a field boundary running along its western side. The track itself was simply absorbed into the landscape, filed away as something else.

The archaeologist Seán P. Ó Ríordáin described it in 1951 as a sunken track lined on both sides by boulders, and the physical evidence bears this out on aerial imagery taken decades later. The road sits within a remarkable cluster of monuments: standing stones lie 45 metres to its west and 30 metres to its east, three enclosures are within 175 metres, and its southern end abuts a megalithic structure. It is also just 220 metres east of the great stone circle at Grange, one of the largest prehistoric stone circles in Ireland. Whether the road predates or simply grew up alongside these monuments is not established, but its incorporation into a historic field system suggests it was a working route for a very long time. Lynch, writing in 1951, traced its course as far south as Kilmallock, and aerial photographs allow it to be followed northward from Loughgur House, continuing along the southern side of Grange Hill as a field monument as far as the Camoge River.

The road is not signposted or managed as a visitor site in the conventional sense, and approaching it requires some orientation. The surrounding area around Lough Gur is well visited, but the trackway itself sits slightly apart from the main interpretive trail. It is most legible from aerial images, and visitors on the ground should look for the slight depression in the land between boulder-lined banks, running across the ridge west of the lake. The section at Ballynagallagh to the south survives separately and is recorded as a distinct monument. The landscape is generally open and grazed, so visibility of the earthwork varies with the season; the ditch lines that flank the sunken road show most clearly when grass is short.
