Inis Mor is the largest of the three Aran Islands (7,635 acres) and includes several ancient stone forts and churches among its antiquities. Most impressive of the stone forts is Dun Aengus. It is semicircular, resting on the edge of a perpendicular cliff rising 100 metres out of the ocean. The fort consists of an inner court 50 metres across surrounded by a wall six metres high and five metres thick at the base. Outside is a rampart, a defence formed by sharp-pointed stones set closely together.
This is a very early church of which little remains. The saint from whom this church derives its name is buried beside the church at the door to the south. In the past the church was an important place of pilgrimage for both island people and pilgrims from the mainland, stations are still held here annually on August 15th.
Inis Meain offers the visitor a superb setting to take in the views of the immediate islands and out towards Galway Bay.
Notwithstanding, the idyllic nature of the island itself will unfold as you walk with hundreds of species of wild flower and the inviting intrigue created from the miles of stone walls and cliffs only gathers momentum as you walk for longer.
There are about 1100 inhabitants on Inis Mor making it by far the most populated of the islands. The main village on the island is Kilronan.
Inishmore is almost too big for just a day trip, but if you only have the one day, the best thing is to get the first ferry to the island and hire a pony trap (or the less romantic means of transport, a taxi, or a tour bus like Inish Mor Tours providing extensive explanations and easy access to most of the sites). Bike hire is also available. There is a supermarket and and a few other shops like the Aran Sweater Market and Museum, a hotel, and two hostels as well as several pubs on the island. Make sure you drop in for a Pint or some Food at the Inismor Bar
