About the region

Discover Kerry & Killarney

Kerry contains Ireland’s highest, sharpest and most concentrated mountain terrain. MacGillycuddy’s Reeks rise between the Lakes of Killarney and the Atlantic, forming a broken chain of sandstone summits, narrow ridges and deeply carved glens. Carrauntoohil is the natural focus, but the surrounding mountains provide some of Ireland’s finest—and most demanding—walking.

The Coomloughra Horseshoe links Beenkeragh, Carrauntoohil and Caher in a serious high-level circuit. The complete Reeks Ridge Traverse is longer still, crossing the range through exposed ground where escape routes are limited and accurate navigation matters.

Killarney National Park offers a gentler side to the region. Woodland paths, waterfalls and lakeside trails spread beneath Mangerton and Torc Mountain, while Purple Mountain rises above the Gap of Dunloe. Native oak and yew woodland survive beside the lakes, alongside Ireland’s only remaining wild herd of native red deer.

Beyond Killarney, Kerry’s mountain country continues along the Iveragh, Dingle and Beara peninsulas. Mount Brandon overlooks the Atlantic from an ancient pilgrimage route, Baurtregaum crowns the Slieve Mish range and quieter summits rise above isolated valleys and coastal villages.

Much of the mountain land is privately owned. Continued access depends on walkers respecting farms, parking responsibly and leaving gates exactly as they find them.

Kerry’s Mountain and National Park Legacy

The Reeks

Ireland’s mountain roof

Carrauntoohil, Beenkeragh and Caher form Ireland’s only group of summits reaching 1,000 metres, connected by steep and exposed mountain ridges.

The Lakes and Woodlands

Killarney National Park

Three great lakes lie beneath Mangerton, Purple Mountain and Torc, surrounded by waterfalls and some of Ireland’s most important native woodland.

The Atlantic Peninsulas

Mountains beside the ocean

The Dingle, Iveragh and Beara peninsulas carry long mountain ridges towards the Atlantic, creating exceptional coast-to-summit walking.

When to visit

Spring

Mar – May

Longer days and improving conditions make spring ideal for Killarney and the lower peninsular hills. Snow or ice can linger on the highest Reeks summits.

Best for: Quieter mountains and woodland trails

Summer

Jun – Aug

Extended daylight suits the Coomloughra Horseshoe and other substantial circuits. Carrauntoohil becomes busy, while more remote Kerry summits remain comparatively quiet.

Best for: Reeks traverses and long mountain days

Autumn

Sep – Nov

Killarney’s oakwoods develop rich colour and cooler air can provide excellent visibility. Atlantic weather becomes increasingly unsettled later in the season.

Best for: Woodland colour and clear Atlantic views

Winter

Dec – Feb

The Reeks can develop snow, ice and severe wind chill. Lower woodland, lakeside and coastal routes provide less committing alternatives.

Best for: Experienced mountaineers and lower park routes
