Through the Stone Gate: Walking the Gap of Dunloe
A seven-mile pass through glaciated peaks, lakes and local lore—walk, photograph or ride through one of Ireland’s most intimate mountain corridors.
A low cloud sits like a grey shawl along the shoulders of MacGillycuddy’s Reeks as you step into the Gap of Dunloe. The track narrows and the mountains close in—sheer walls of green-brown rock rise on either side, streaked with old landslides, peat and thin silver streams. The path is a ribbon of stone and heather, worn into the landscape by centuries of feet, horses and cartwheels. Ahead, the river dares you forward, chattering in the rocks, guiding the valley toward a line of lakes that mirror the sky.
Trail Wisdom
Plan a one-way route
Arrange boat pickup or a return shuttle in advance—many visitors walk one way and take a boat across the Lakes of Killarney back to Ross Castle to avoid retracing the entire 11 km route.
Wear sturdy, waterproof shoes
The path is uneven with boggy patches and river stepping stones; ankle support and grip will make the walk comfortable and safe.
Bring cash for jaunting cars and café stops
Some local services and cafés still prefer cash—carry small notes for jaunting car fares (€25–€35) and refreshments at Lord Brandon’s Cottage.
Start early for light and solitude
Begin at dawn or early morning to catch soft light for photography and avoid the busiest mid-day tour groups and jaunting cars.

Conservation Note
The Gap lies within Killarney National Park—stay on marked paths to protect sensitive blanket bog and peat; support operators who follow Leave No Trace principles.
The Gap was shaped by glaciation during the last Ice Age and later became a drovers’ route; local cottages like Kate Kearney’s feature in 19th-century travel literature and folklore.
Seasonal Guide
spring
Best for: wildflowers, photography, moderate hiking
