Fodor's Expert Review Gap of Dunloe

Massive, glacial rocks form the sides of this narrow mountain pass that stretches for 6½ km (4 miles) between MacGillicuddy's Reeks and the Purple Mountains. The Gap is a natural auditorium where sound waves can bounce from stone to return---creating almost an echo chamber, which can be fun to test out with a shout. Five small lakes are strung out beside the road. Cars are banned from the Gap, but in summer the first 3 km (2 miles) are busy with horse and foot traffic, much of which turns back at the halfway point. The entrance to the Gap is 10 km (7 miles) west of Killarney at Beaufort on the N72 Killorglin Road. If you drive or are on a tour bus, stop here and either hire a pony and trap or opt to walk. One advantage to an organized tour—and a popular option—is that, without the need to get back to your car, you can amble through the parkland as far as Lord Brandon's Cottage, then get a prebooked boat back to Killarney town.
