In recent times the popularity of the Camino de Santiago has prompted renewed interest in pilgrim walks in Ireland. Increasing numbers now follow ancient Irish pilgrim paths. Irish people have a particular sensitivity to holy places, such as Clonmacnoise, Croagh Patrick, Lough Derg and Glendalough. John G. ODwyer has walked the ancient pilgrim routes of Ireland, from Slemish Mountain in the northeast, where Christianity may have had its first dawning in Ireland, to Skellig Michael in the southwest, where the known world once ended. Each pilgrim walk description has directions, the degree of difficulty, estimated time and maps. The paths are varied and suitable for all, from casual ramblers to committed hillwalkers. In each route description the authors feelings and experiences are recounted, the entertaining and insightful characters met along the way described. On the pilgrim routes the search for spiritual fulfilment continues in twenty-first century Ireland.
