The Kerry Way is Ireland’s longest waymarked walking trail, a roughly 214-kilometre (133-mile) loop around the Iveragh Peninsula that starts and finishes in the town of Killarney. It is not a high-mountain route — the trail deliberately stays in the valleys and the highest point is only around 400 metres — but it strings together some of the finest low-level walking in Ireland: Killarney’s lakes, the remote Black Valley, Atlantic coastal paths, and mountain views that arrive without the need to climb them. Most walkers finish in nine to eleven days, following nine official stages.
Route at a glance
The nine official stages are: Killarney to Black Valley (about 23 km), Black Valley to Glencar (21 km), Glencar to Glenbeigh (16 km), Glenbeigh to Cahersiveen (28 km), Cahersiveen to Waterville (30 km), Waterville to Caherdaniel (13 km), Caherdaniel to Sneem (19 km), Sneem to Kenmare (30 km), and Kenmare back to Killarney (25 km). The middle days are the longest, so many walkers split or combine stages to suit their fitness — seven-day and twelve-day itineraries are both common, and the loop format means you can start at any point. The trail is waymarked throughout with the yellow walking-man symbol, so navigation is straightforward even for first-time long-distance walkers.
Getting there
Killarney is the natural base: it has a train station with direct services from Dublin, and buses connect it with Cork, Limerick and Shannon Airport. From Dublin Airport, most walkers take the train or a bus combination to Killarney and spend a night in town before setting off. Because the route is a loop, you finish where you started, which keeps onward travel simple. If you want to break the walk, the Ring of Kerry road bus route passes through several of the same towns, giving you easy bail-out options.
Best time to walk
Late spring to early autumn — roughly May through September — is the practical window. May and June bring long daylight (over 16 hours around midsummer) and generally the driest conditions; July and August are the warmest but also the busiest, with Irish family holidays filling accommodation. September is a favourite among regulars: the crowds thin out, the light softens, and midges are less of a nuisance. This is Ireland, so rain is a possibility in any month — pack waterproofs regardless of the forecast.
Costs and accommodation
You will not find designated campsites along most of the route, and wild camping is generally discouraged, so the Kerry Way is a B&B, guesthouse and hostel walk. Each stage ends in or near a village with accommodation, from family-run B&Bs to walkers’ hostels. Book well ahead for the May-to-September season — the Iveragh Peninsula is popular with all kinds of tourists, and last-minute beds can be scarce or expensive. Several operators offer luggage-transfer services between overnight stops, so you can walk with just a daypack if you book ahead. Eating is easy: village pubs and cafés serve lunch and dinner, and small shops cover trail snacks.
Practical tips
Bog is the Kerry Way’s signature hazard. Sections cross farmland and open hillside that get seriously waterlogged after rain, so waterproof boots with good ankle support are close to essential, and gaiters earn their place on wet weeks. Streams and taps along the route generally make refilling water straightforward, though filtering is sensible for stream water. The Gap of Dunloe makes a spectacular alternative start or side trip from Killarney if you have a spare day. Finally, carry cash: rural pubs and some B&Bs still prefer it, and ATMs are not guaranteed in the smaller villages.
Worth the detours
Two add-ons repay the extra effort. The Gap of Dunloe — a narrow mountain pass carved between the MacGillycuddy’s Reeks and Purple Mountain — can be walked from Killarney as a dramatic first or last day, with the option of a boat ride back across the lakes. And Killarney National Park itself, which the trail skirts at the start, holds Muckross House, Torc Waterfall and old oak woods that make a gentle warm-up walk before the longer days begin. If the full loop feels like too much, the trail’s loop format means sections like Glenbeigh to Waterville work beautifully as standalone long weekends.
