This pint-sized island lies tantalisingly close to the lough's southeastern shore, but, alas, can't be accessed. Still, it's visible from the shore. Its air of tranquillity so moved Yeats that he famously wrote 'The Lake Isle of Innisfree' (1890):
'I will arise and go now, and go to Innisfree,
And a small cabin build there, of clay and wattles made;
Nine bean rows will I have there, a hive for the honey bee,
And live alone in the bee-loud glade.'
Access the best vantage point of the island from a small road that starts at the junction of the R287 and the R290. Follow the winding lane for 4.2km to a small parking area by the water.
