Kilronan (Cill Rónáin) is the main village on Inis Mór, the largest of the Aran Islands. The ferry from Rossaveal or Doolin drops you at the pier here, and this is where you will find the island's few pubs, shops, and B&Bs.
The village itself is small — a handful of buildings around the harbour — but it is the starting point for exploring the island. Dún Aonghasa, the spectacular Iron Age cliff fort on the western edge of Inis Mór, is about 8 km away by road. Most visitors rent a bike in Kilronan and ride out along the stone-walled lanes, stopping at Dún Dúchathair and the tiny oratory of Teampall Bheanaín, before finishing at Joe Watty's Bar for a pint. The Aran Heritage Centre in the village shows Robert Flaherty's classic 1934 film Man of Aran — good context before you set out.
