Reeks of Kerry – Ireland’s highest mountains, darkest skies

📍 Southwest County Kerry, Kerry

🏛️ Attraction

Last updated: 12 June 2026

Overview

The only three mountains in Ireland over 1,000 metres stand in a single ridge here: Carrauntoohil at 1,038m, flanked by Beenkeragh and Caher. The Reeks District – the country between the Ring of Kerry and the Dingle Peninsula – runs from those summits down to Blue Flag sand at Castlemaine Harbour, and Rough Guides put it on its Best Places to Visit list in 2019. It also holds Ireland’s only Gold-Tier International Dark Sky Reserve, which matters more than the label suggests: on a clear, moonless night between September and April, this is the best Milky Way viewing in the country.

The mountains

The Reeks are Old Red Sandstone carved by Ice Age glaciers into U-shaped valleys and corrie lakes – Lough Coomloughra is the finest of them – with Bronze Age stone forts and standing stones scattered across the lower ground. The three 1,000m summits count among the 13 Irish Furths, the peaks over 3,000 ft outside Scotland, and bagging all three along the MacGillycuddy’s Reeks Ridge is the classic high-level day: demanding, exposed and worth the planning.

Most Carrauntoohil ascents start from Cronin’s Yard, where the car park takes a voluntary €2. Be straight about the routes. The Devil’s Ladder, the traditional way up, is loose and slippery – ‘soapy’ is the word local climbers use – and no fun in descent. O’Shea’s Gully can hold ice in winter. The Hag’s Tooth path is a steep scramble. Conditions change fast above 800m in any month, so carry a map and proper boots, and if you’re not used to mountain terrain take a guide – Kerry Climbing runs led ascents of Carrauntoohil and its neighbours. Jim Ryan’s Carrauntoohil & MacGillycuddy’s Reeks (Collins Press, 2007) details 20 routes if you’d rather plan your own, and the Great Outdoors 1:25,000 map series covers the range.

Lower-level walking is plentiful: the Kerry Way crosses the district, including a 14 km Kells-to-Glenbeigh stretch with sea views, and Caherconree carries the highest stone fort in Ireland at 683m.

Off the hills

The district markets a ‘Big Five’ – climb Carrauntoohil, surf Inch Beach, kayak Caragh Lake, cycle the 90 km Ring of the Reeks, and paddleboard Lough Cloon by night under the dark skies (details). You don’t need all five. If you pick one beyond the mountains, make it Inch: the beach holds a consistently surfable wave year-round, with June to August the warmest water for beginners. It’s also the fallback when cloud sits on the Reeks.

The Ring of the Reeks cycle takes in the Ballaghbeama Gap, Moll’s Gap and the Gap of Dunloe. Wild swimmers use Lough Coomloughra, Kells Bay and Coonanna Harbour. Guided horse rides on the Killarney Reeks Trail cross woodland and mountain track to Rossbeigh, a 6 km Blue Flag strand where the wreck of the 19th-century schooner Sunbeam occasionally reappears from the sand.

Killorglin and the calendar

Killorglin is the working capital of the district, with the visitor centre – free maps and trail-condition reports, typically 10am–4.30pm in high season – and the River Laune, a serious salmon and sea-trout fishery, running through it. Its big moment is Puck Fair, 10–12 August, billed as the world’s oldest livestock fair, when a goat is crowned king of the town. K-Fest brings music and art over the June bank holiday weekend, the Flavour of Killorglin food festival follows in early September, and walking festivals mark May Day, Bealtaine, Lughnasa and Samhain. For dinner, Sol y Sombra in Killorglin and Jack’s Coastguard Restaurant in Cromane both fill quickly in season – book.

Practical

Kerry Airport is about 20 minutes from Killorglin, with flights from Dublin, London, Frankfurt, Berlin, Alicante and Faro; Dublin is a four-hour drive, Shannon two, and a car is close to essential. Most trailheads and beaches have free parking. June to August is the busy season; April–May and September–October are quieter and still good walking months, though the weather turns faster. Caragh Lake sits within a Special Area of Conservation, and lodging runs from B&Bs to lakeside houses like Carrig Country House – listings at reeksdistrict.com. Beyond the district, boats for the Skellig Islands leave Portmagee from May to September (booking essential) and Killarney National Park is next door to the east.

Whatever you plan, check the forecast the night before: above 800m the Reeks make their own weather.
