Known locally as Tobar Na Bearnan, it was not a place of casual devotion but the final, hard-won destination of a formal pilgrimage circuit. To arrive at a holy well perched at such an altitude, after completing the earlier stations of the route below, would have carried a particular weight, both physical and spiritual.

The well served as the last stop on the Kilcrohane turas, a turas being a structured devotional circuit of sacred sites, typically walked in a prescribed order with prayers said at each station. This one was held in late July or early August, and the well's water was believed to cure eye conditions, a tradition documented by Ó Suilleabháin in 1945. What makes the site especially striking is the carved stonework beside it: a flat slab measuring roughly forty by twenty centimetres, incised with a cross that carries a smaller cross in each of its four angles. This kind of incised cross slab is a feature found at early Irish Christian sites across the country, and here it retains an active ritual function. Lying alongside the slab is an elongated stone point, used by pilgrims to trace the sign of the cross onto the carved surface, a gesture that has worn its meaning into the stone over generations.

The well sits on the south-eastern side of the cairn, and the ensemble of spring, carved slab, and pointing stone together form a small but coherent sacred landscape. The late July timing of the old pilgrimage season is worth bearing in mind for anyone approaching Eagles Hill; the surrounding moorland and quartz-flecked cairn read very differently under a clear summer sky than in the grey Atlantic weather that rolls in for much of the year.
