Killarney sits at the northern edge of the MacGillycuddy’s Reeks, Ireland’s highest mountain range, with three lakes spread out beneath it and 26,000 acres of national park on its doorstep. It is one of the most visited towns in Ireland — and in March 2026, it became one of the most searched. Jessie Buckley, who grew up here, won the Best Actress Oscar for her role in Hamnet, becoming the first Irish woman ever to win that award. If you are looking for things to do in Killarney, you have picked the right moment. The town that shaped one of cinema’s finest actors is very much open for visitors.
The Best Things to Do in Killarney, Ireland
Killarney has drawn visitors since the 18th century, when wealthy tourists travelled to Kerry specifically to see the lakes. Queen Victoria visited in 1861. The scenery has not changed. What has changed is the infrastructure — Killarney is now one of the most well-organised visitor towns in Ireland, with excellent accommodation, restaurants, and transport connections to the rest of Kerry.
The town is compact and walkable. You do not need a car to explore the national park — jaunting cars, cycling, and walking trails all start from the town centre. Most visitors use Killarney as a base for the Ring of Kerry and Dingle Peninsula as well. Three or four nights here gives you enough time to do all of it properly.
For visitors from the USA, Killarney is an easy entry point. Kerry Airport has seasonal direct connections from the US, and Cork Airport — a 90-minute drive — has more year-round options. From Dublin, it is a three-hour drive or a three-hour train journey on the Irish Rail intercity service.
The Arbutus Hotel — The Buckley Family Legacy
Jessie Buckley was born in Killarney in 1989. Her family has owned the Arbutus Hotel on College Street since 1926. That is four generations of the same family running the same hotel in the same town — the kind of continuity that is rare anywhere, and quintessentially Irish.
The Arbutus is a proper Irish town hotel — warm, well-run, with a bar that has been central to Killarney life for a century. Jessie’s father, John Buckley, still runs it. If you want a direct connection to Killarney’s most famous recent export, this is the place to stay or at least stop in for a pint.
Killarney has a strong musical and artistic tradition. Jessie came second on RTÉ’s Fame: The Musical in 2008 and went on to study at the Royal Academy of Dramatic Art in London. Michael Fassbender — known for X-Men, 12 Years a Slave, and Steve Jobs — was also raised partly in Killarney before his family moved to Cork. The town is quietly proud of both of them.
Killarney National Park
Killarney National Park was the first national park in Ireland, established in 1932. At 26,000 acres it covers mountains, lakes, native oakwood forests, and blanket bog. The variety inside a single park is unusual — you can walk from dense oakwood into open mountain moorland in under an hour.
The three lakes — Lough Leane, Muckross Lake, and the Upper Lake — are connected and run for about seven miles through the park. Lough Leane is the largest and most photographed, with Ross Castle on its western shore and Innisfallen Island visible a short boat ride from town.
The park is free to enter. Main access points are near Muckross House, at Ross Castle, and at the Torc Waterfall car park on the N71. Torc Waterfall is a short walk from the road and one of the most photographed spots in Kerry. Red deer roam freely through the park — Ireland’s only native red deer herd. You are likely to see them near the lakes in the early morning.
Ross Castle
Ross Castle stands on a rocky peninsula at the south-western edge of Lough Leane. The O’Donoghue Mór clan built it as their stronghold. Cromwellian forces did not take it until 1652, after bringing artillery across the lake by boat. Guided tours run throughout the day. From the castle, you can take a boat trip onto the lake or hire a rowing boat for a quieter outing.
Muckross House and Gardens
Muckross House is a Victorian mansion built in 1843 for Henry Arthur Herbert, an MP and Kerry landowner. Its most famous moment came in 1861 when Queen Victoria visited — Herbert refurbished the entire estate at enormous cost for the occasion. The debt ruined him.
Arthur Bourn Vincent donated the house to the Irish state in 1932, and it became the nucleus of the national park. Today it opens for guided tours, and the basement shows Victorian domestic life — kitchens, laundry, servants’ quarters. The walled garden is worth visiting in summer when the herbaceous borders are at their peak.
The Traditional Farms adjacent to the house recreate working Irish farms from the 1930s. There are animals, demonstrations of traditional crafts, and staff in period clothing. The combination of the house, farms, and surrounding gardens gives you a half-day easily.

The Gap of Dunloe
The Gap of Dunloe is a narrow mountain pass carved by glaciers between the MacGillycuddy’s Reeks and the Purple Mountain. The road through it is narrow, often single-track, and unsuitable for larger vehicles. That is part of the appeal. It is best experienced on foot, by bicycle, or by jaunting car.
The classic excursion combines all three: jaunting car from Killarney to Kate Kearney’s Cottage at the entrance to the Gap, walking or cycling through the Gap (about eight kilometres), then a boat trip across the three lakes back to Ross Castle. This full-day excursion is one of the finest ways to see the Kerry landscape. Book transport in advance during summer.
Kate Kearney’s Cottage — named after a 19th-century local beauty said to offer poitín to passing travellers — is now a pub and restaurant at the mouth of the Gap. It is a good place to stop for a meal before or after the walk.
The Ring of Kerry and Day Trips from Killarney
Killarney is the natural starting point for the Ring of Kerry, the 179km scenic route that circles the Iveragh Peninsula. The full ring takes a day by car. Kenmare, Waterville, Caherciveen, and Portmagee are the main stops, with views of the Atlantic and the Skellig Islands throughout.
Skellig Michael — the UNESCO World Heritage Site where much of Star Wars: The Force Awakens was filmed — is accessible by boat from Portmagee. Boats run from May to early October, weather permitting. Numbers are strictly limited and places sell out months in advance. Book well before your trip if Skellig Michael is a priority.
The Dingle Peninsula is 40 minutes north of Killarney and offers a different experience — Irish-speaking in parts, with the Slea Head Drive, Gallarus Oratory, and the town of Dingle itself. Four nights based in Killarney gives you enough time to do both the Ring of Kerry and Dingle without rushing.
For a full Ireland route that builds Killarney into a complete circuit, our 7-day Ireland itinerary from the USA covers the southwest in detail. If you have more time, the 10-day Ireland itinerary for American travellers adds the north and the midlands.
Planning Your Visit to Killarney
When to Go
July and August are the busiest months. June and September offer better weather than you might expect, with significantly smaller crowds. Spring — April to May — can be beautiful. The Kerry landscape is at its most vivid green in spring, and the roads are quiet. Winter visits are possible and increasingly popular, with the national park largely empty and accommodation prices lower.
How Long to Stay
Three nights is the minimum to cover Killarney town, the national park, and one day trip. Four nights lets you do the Ring of Kerry and the Dingle Peninsula both. See our full County Kerry guide for a wider look at the region. For budget planning, our Ireland trip cost guide for US visitors covers flights, accommodation, and daily costs across the country.
