A fourth kind of visitor to the islands, still prominent today, comes for spiritual reasons often connected to an appreciation for Celtic Christianity or more modern New Age beliefs, the former of which finds sites and landscapes of importance on the islands. Finally, there are many thousands of visitors who come for broadly touristic reasons: to see the ruins, hear Irish spoken (and Irish music played) in the few pubs on the island, and to experience the often awe-inspiring geology of cliffs. Tourists today far outnumber visitors of the four kinds discussed above. Tourists and visitors of the fourth kind, however, are under-represented as creators of literature or art directly connected to the island; there are few ordinary "travelogues" of note, perhaps because of the small size of the islands, and there are no personal accounts written about Aran that are primarily concerned with spirituality. Tim Robinson's Stones of Aran: Pilgrimage (1986) and Stones of Aran: Labyrinth (1995), and his accompanying detailed map of the islands, are another resource on the Aran Islands. Robinson's work is an exhaustive, but not exhausting, survey of the Aran geography and its influence on Aran culture from the Iron Age up to recent times. Robinson also has written, and continues to write, about the Connemara region that faces the Aran Islands on the Galway mainland.
