At the highest point of the hill, the southern end of the ridge, are two large cairns. The northern cairn is an impressive 20m across. A Bronze Age reave heads WSW down the hill directly from it. But the southern cairn, the Eylesbarrow itself, is bigger still. Another of the reservoir catchment markers stands between the two cairns, on a windswept spot that will be the highest point of my walk today. Without hanging around very long, I follow the reave down the hill.
