Killarney Walks: The Complete Guide to Walking in Killarney National Park

Killarney National Park has walks for every level, and most of them start within a few kilometres of the town centre. If you only have a couple of hours, the flat paths around Knockreer, Ross Island and Muckross are hard to beat. If you have a full day and some hill experience, the Old Kenmare Road, Torc Mountain and Mangerton take you up into proper mountain country.

This guide brings together the main Killarney walks in one place, with distances and grades taken from the National Parks and Wildlife Service (NPWS) wherever they publish them. Where official sources disagree or don’t give a figure, we say so, so you can check before you go.

Killarney National Park at a glance

Killarney National Park was Ireland’s first national park. It began in 1932, when the Bourn Vincent Memorial Park, including Muckross House, was presented to the State. Today the park covers more than 10,000 hectares of lakes, oak and yew woodland, bog and mountain, right on the edge of Killarney town. It is also home to Ireland’s only native herd of red deer, which have lived here since prehistoric times, and it is part of a UNESCO Biosphere Reserve.

A few practical points that make planning easier:

• Access is free. According to the NPWS Killarney National Park website, the park is open to walkers 24 hours a day, all year round. Gardens at Killarney House and Muckross House have their own opening hours.
• Parking in the park is free, including at Muckross House, Ross Castle and the Torc car parks.
• Dogs are welcome on the trails but must be kept on a lead at all times.
• Cyclists share some routes, especially around Muckross, Knockreer and Ross Island, and some cycle routes are one-way. Keep left and listen out for bells.
• Jaunting cars (horse and trap) operate under NPWS permit on several routes, so you will often share the roads near Muckross and Ross Castle with them.

The Killarney National Park Visitor Centre is at Killarney House, near the town centre, and there is an information point at the Muckross House car park. Muckross House itself is about 6 km from town along the N71 Kenmare road.

Easy Killarney walks (good for families and a first visit)

These walks are mostly flat, on good paths, and graded Easy by NPWS. Normal trainers are fine in dry weather, though paths around the lakes can be muddy after rain.

Knockreer Circular (5 km, Easy)

The closest walk to town and a lovely first taste of the park. The loop starts at Killarney House and climbs gently to about 45 m above the lake, giving wide views over Lough Leane to the mountains. NPWS suggests allowing around two hours, but you can easily shorten it. If you are driving, NPWS advises using on-street parking on Port Road, opposite St Mary’s Cathedral.

Quick facts: Knockreer Circular

Distance	5 km loop (NPWS)
Grade	Easy
Time	About 2 hours
Start	Killarney House & Gardens, town centre
Parking	On-street, Port Road (opposite St Mary’s Cathedral)
Surface	Mostly paved paths

Ross Island Mining Trail and Library Point

From Ross Castle, a 15th-century tower house on the shore of Lough Leane, several short trails explore Ross Island. The Mining Trail visits the remains of copper mines that were worked here from the Bronze Age, with information points along the way. NPWS lists it as a 3 km loop, while Discover Ireland gives 2 km. Library Point (5 km loop) and Governor’s Rock are other easy options from the same car park.

Lakeside Walk to Muckross House (5 km return, Easy)

A flat path from the park entrance on the N71 to Muckross House, with the lake on one side and old woodland on the other. Combine it with a visit to Muckross House and gardens, or with the short Old Boathouse Trail (1 km).

Dundag to Torc path (2.5 km return, Easy)

A short, easy path from Dundag Point towards Torc Waterfall. It is a good way to see the waterfall without climbing the steps beside it.

Moderate walks around Muckross

The Muckross peninsula has a network of woodland and lakeside trails. They are graded Moderate because of some climbs, roots and uneven ground.

• Arthur Young’s Walk (5.6 km loop) starts at Muckross House and takes you through some of the park’s most beautiful yew and oak woodland.
• Mossy Woods (2 km loop), also from Muckross House, is short but atmospheric, with moss-covered rocks and trees.
• Killegy Woods and Queen’s Drive (3 km loop) starts at the Blue Pool entrance and climbs for views over the lakes.
• Cloghereen Nature Trail (1 km) near Muckross House was Ireland’s first trail designed for visitors with visual impairments, with a guide rope along the route.
• Dinis and Old Weir Bridge (1 km loop) is a short walk near Dinis Cottage at the Meeting of the Waters. NPWS warns that it is often flooded.

The Muckross Lake Loop

The most famous walk in the area is the circuit around Muckross Lake, passing Dinis Cottage, the Meeting of the Waters and Brickeen Bridge. It is mostly on surfaced paths and quiet roads with little climbing. Discover Ireland suggests allowing about three hours for the quickest circuit, plus extra time if you add the detour to Torc Waterfall. Published distances vary depending on where you start, so check the park map before you set out. We cover the route step by step in our Muckross Lake Loop walk guide.

Torc Waterfall and Torc Mountain

Torc Waterfall is one of the most visited spots in the park, and for good reason. From the Torc car park on the N71 it is only about five minutes’ walk to the falls, which tumble around 20 m through the woods (some sources say 18 m). Steps continue up beside the waterfall, and from the top you can join the Old Kenmare Road.

For a bigger day, Torc Mountain (535 m) rewards you with one of the best views in Kerry over all three lakes. The usual route leaves from the upper Torc car park, follows the Old Kenmare Road and then climbs a stepped path and boardwalk to the summit. It is a proper hill walk, so good boots and a waterproof are essential. Our Torc Waterfall walk guide covers both the short waterfall walk and the mountain.

Please keep the small lower car park at Torc free for people with limited mobility, as NPWS requests.

Strenuous walks: the Old Kenmare Road, the Mass Path and Mangerton

Old Kenmare Road

This old route between Killarney and Kenmare runs through remote valleys behind Torc and Mangerton, and today it forms part of the Kerry Way. NPWS grades the section from the upper Torc car park to Incheens as Strenuous and gives it as 7 km. It is linear, so you will need to arrange a lift, walk back the same way, or continue towards Derrycunnihy. Some sections are boggy, and boots are a must. If you enjoy it, take a look at our guide to walking the Kerry Way.

The Mass Path

A 4 km (one way) trail from Derrycunnihy Church to Lord Brandon’s Cottage, graded Strenuous by NPWS. It can flood in winter, so it is best kept for drier months.

Mangerton Mountain and the Devil’s Punchbowl

At about 838 m, Mangerton is one of the highest mountains near Killarney. On its northern side is the Devil’s Punchbowl, a dramatic corrie lake. The walk to the summit follows a track from the car park off the Kenmare road and takes most walkers a couple of hours each way. In cloud the broad summit plateau can be confusing, so only go up if you can navigate with a map and compass.

The Gap of Dunloe

Just west of the park, the Gap of Dunloe is a narrow mountain pass of about 11 km between Kate Kearney’s Cottage and Lord Brandon’s Cottage, squeezed between the MacGillycuddy’s Reeks and the Purple Mountain range. The road through the Gap is narrow and you will share it with jaunting cars and cyclists, but traffic is light compared with main roads and the scenery is spectacular.

A popular way to do it is to walk or cycle through the Gap, then take a boat from Lord Brandon’s Cottage back across the lakes to Ross Castle. Boats are run by private operators and are seasonal, so book ahead. All the details are in our Gap of Dunloe walking guide.

When to visit

Killarney is beautiful at any time of year, and each season has its own character. Late spring brings bluebells and long evenings, summer is busiest, autumn colours in the oak woods are wonderful, and winter can be quiet and atmospheric. In winter some low-lying paths, such as the Mass Path and the Dinis trail, are prone to flooding, and daylight is short, so plan shorter walks and start early.

Whatever the season, check the Met Éireann forecast before you go. The weather in the mountains can be very different from the weather in town. For clothing tips, see what to wear walking in Ireland.

Staying safe on Killarney walks

Most trails in the park are low-level and straightforward, but the surrounding mountains are serious terrain. NPWS advises staying on marked trails, telling someone your plans, and only heading into the hills if you are experienced. The park map is not suitable for hill walking, so carry a proper map if you go higher.

• In a mountain emergency, call 112 or 999 and ask for Mountain Rescue. Kerry Mountain Rescue responds to callouts across the county.
• Carry a charged phone, a torch, water, food and a warm, waterproof layer, even on short walks.
• For general park queries, NPWS has a Duty Ranger service: +353 64 6635215 (9am–5pm).
• Watch for ticks in long grass and bracken, and check yourself after walks.
