The town is on the northeastern shore of Lough Leane, which is part of Killarney National Park. The town and its hinterland is home to St Mary's Cathedral, Ross Castle, Muckross House and Abbey, the Lakes of Killarney, MacGillycuddy's Reeks, Purple Mountain, Mangerton Mountain, the Gap of Dunloe and Torc Waterfall. Owing to its natural heritage, history and its location on the Ring of Kerry, Killarney is a popular tourist destination.

In 2011 it was named Ireland's tidiest town and the cleanest town in the country by Irish Business Against Litter.
