Killarney National Park: Exploring Mountains, Lakes, and Castles

After traveling to Ireland several times now, I can safely say that Killarney National Park (Páirc Náisiúnta Chill Airne in Irish) and its surroundings rank among my favorite parts of the country. The stunning landscapes, rich history, and vibrant culture here rival the likes of Dublin and the Cliffs of Moher!

When you think of Ireland, you likely envision rolling green fields and charming villages. Killarney certainly meets those expectations, offering some of the best natural wonders in the country. Nestled on the shores of Lough Leane in County Kerry, Killarney is part of the famous “Ring of Kerry,” a scenic drive that attracts countless tourists from around the globe.

Whether you’re in the mood for a deep dive into Irish culture and history in Killarney Town or prefer outdoor adventures in Killarney National Park, this area has it all. After having an amazing time, I wanted to share some of my favorite things to do in Killarney, Ireland, for those planning a trip.

Best Things To Do In Killarney

1. Visit Killarney National Park

Killarney National Park is a paradise for outdoor enthusiasts, featuring mossy valleys, ancient woodlands, and stunning mountain ranges, along with historic castles and enchanting lakes. Established in 1932 when Muckross Estate was donated to the Irish Free State, this park spans over 25,000 acres.

Outdoor lovers can explore the diverse ecosystems, including the scenic Lakes of Killarney, oak and yew woodlands, and various wildlife. Entrance to the national park is free, although some attractions within may have entry fees. Many highlights mentioned below are located within the National Park, while others are just a stone’s throw away, ensuring a plethora of activities to enjoy.

2. The Muckross House

The Muckross House is one of the most iconic attractions within Killarney National Park. This stunning Victorian mansion, built in 1843 for Henry Arthur Herbert and his wife, watercolorist Mary Balfour Herbert, offers a glimpse into the grandeur of the past. The estate features exquisite gardens that bloom vibrantly throughout the seasons.

Visitors can tour the house, gardens, and working farms year-round. The interiors are beautifully preserved, showcasing elegant period furniture that reflects the lifestyle of its former inhabitants. The grounds also include the ruins of Muckross Abbey, famous for a tree growing inside its walls, adding a touch of nature to the historical site.

Opening Times: 9 AM – 6 PM
Entry Fee: House tours cost €9, while wandering the grounds is free.

3. Explore Ross Castle

Located on the edge of Lower Lake in Killarney National Park, Ross Castle is a beautifully restored structure built by the O’Donoghue clan in 1537. With a rich history of battles and legends, the castle offers guided tours during the summer months.

Visitors can embark on boat trips from Ross and Reen piers to Innisfallen Island, home to ancient ruins of an abbey, and to Lord Brandon’s Cottage on Upper Lake. Local lore suggests that O’Donoghue, the castle’s original owner, jumped to his death from a window and still haunts the lake, riding his white horse every seven years on May 1st. Those lucky enough to see him are said to be blessed with good fortune!

Opening Times: March 7th – October 22nd: 9:30 AM – 5:45 PM
Entry Fee: No fee to enter; guided tours are €5.

4. Old Weir Bridge

Old Weir Bridge is a picturesque ancient stone arch bridge where the three main lakes of Killarney converge. Dating back to the 16th century, its rustic charm is best accessed by foot, bike, or boat tour, as there is no direct road access.

To reach the bridge, park at the N71 and walk to Dinis Cottage, where you can enjoy a coffee before following the footpath to Old Weir Bridge. This serene spot offers great photo opportunities and a peaceful retreat from the busier tourist attractions.

5. Red Deer Spotting

While exploring Killarney National Park, keep an eye out for red deer, Ireland’s largest mammal and the second largest in Europe. With their distinctive reddish-brown coats, male stags can weigh up to 240 kg (530 lbs) and sport impressive antlers.

You can see red deer year-round, but the best time to spot young fawns is during late spring. I was fortunate enough to visit in October during the annual deer rut when rival stags clash for the attention of females. The best places to see these majestic animals include the Knockreer Estate near St. Mary’s Cathedral and the Muckross House area. Listen for their haunting calls echoing through the park!

6. Visit Killarney’s Beautiful Lakes

The Lakes of Killarney are a must-visit destination for enjoying the outdoors and observing wildlife. Surrounded by lush woodlands and towering mountains, the three lakes—Lough Leane, Muckross Lake, and Upper Lake—offer a range of activities.

• Lough Leane: The largest of the three lakes, it’s often referred to as the Lower Lake. Consider taking a boat trip to Innisfallen Island, where ancient abbey ruins dating back to 600 AD can be explored.
• Muckross Lake: Known as the Middle Lake, it features the Muckross Lake Loop footpath, a scenic trail that takes 3-5 hours to walk. Don’t miss the nearby Torc Waterfall, which cascades 18 meters (60 feet) into a picturesque pool.
• Upper Lake: The smallest and southernmost lake is renowned for its excellent fishing, particularly for salmon and brown trout.

For a unique experience, consider booking a boat or kayak tour to explore the lakes up close!

7. Carrauntoohil & The Macgillycuddy Reeks

One of my favorite experiences in Ireland was hiking Carrauntoohil, the tallest mountain in the Macgillycuddy’s Reeks mountain range. Numerous trails lead to its summit, each offering a unique perspective of the rugged landscape.

I opted for the challenging Coomloughra Horseshoe route, a 6-8 hour trek that traverses all three of Ireland’s highest peaks: Beenkeragh, Carrauntoohil, and Caher. While the views are rewarding, it’s essential to exercise caution as weather conditions can change rapidly. These mountains may not be the tallest in the world, but they can be treacherous!

8. Check Out Torc Waterfall

Torc Waterfall is a popular attraction just a short 5-minute walk from the road, making it an ideal stop for families. The waterfall drops an impressive 80 feet into a serene pool, surrounded by lush woodlands.

For those seeking adventure, several trails loop around the waterfall. The Torc Mountain Trail is a rocky 2-hour hike that provides stunning views of Killarney National Park. Alternatively, try the Huntsman’s Hill trail, which loops 3.5 km (2.1 miles), or the more moderate Torc Loop, which takes about 40 minutes to complete.

9. St. Mary’s Cathedral

Located just a five-minute walk from Killarney’s shopping precinct, St. Mary’s Cathedral showcases impressive stonework and stunning stained glass windows. The soaring ceilings create ideal acoustics, making it a popular venue for weddings and church services.

Designed by renowned architect Augustus Welby Pugin, construction began in 1842 but was paused during the Great Famine. The cathedral was finally completed in 1907, and its intricate details make it a must-see.

10. Castlelough Castle (McCarthy Mor)

Overlooking Lough Leane, Castlelough Castle has a rich history dating back to the 12th or 13th century when it was built by the Anglo-Norman De Roches. The castle changed hands to the Gaelic MacCarthys after a battle in 1262 and remained under their control until the mid-18th century.

Today, the ruins sit next to the Lake Hotel and Castlelough Restaurant, surrounded by beautiful mountains and woodlands, making it an ideal spot to stay while exploring the Irish countryside.

11. Walk the Gap of Dunloe

The Gap of Dunloe is a stunning narrow mountain pass formed over 25,000 years ago by a glacier breach. It separates the MacGillycuddy’s Reeks mountain range from the Purple Mountain range and offers breathtaking views.

The name Dunloe comes from the Irish Dún Lóich, meaning “Lóich’s stronghold.” Legend has it that Mac Lóich was the father of five chieftains who ruled Ireland for 37 years from 3266 BC. The road is single-lane, but I recommend walking or biking, or taking a jaunting cart from Kate Kearney’s Cottage. The 5-mile round-trip journey passes charming farms, lakes, and rugged mountains.

12. Driving the Ring of Kerry

Killarney serves as the starting point for the Ring of Kerry, a famous circular road trip in Ireland. This scenic route showcases ancient stone ruins, mossy green hills, and craggy shorelines along the coast.

Meant to be driven counter-clockwise due to some single-lane roads, the route passes many scenic and historical landmarks, including:

• Killorglin (Home of the Goat King)
• Ballycarbery Castle
• Leacanabuaile Stone Forts
• Ladies View
• Moll’s Gap
• Derrynane Beach
• The Skellig Ring
• Kerry Cliffs

Unfortunately, I didn’t have time to drive the Ring of Kerry, as I found plenty to explore around Killarney for three days before heading north to the Dingle Peninsula.

Where to Eat in Killarney

Murphy’s of Killarney

For a true taste of local life, head to Murphy’s of Killarney. This cozy pub features live music and a welcoming atmosphere, making it a great place to enjoy traditional pub fare, including shepherd’s pie, Guinness beef stew, and fish and chips.

Bricin

Bricin, meaning “small trout” in Gaelic, is a popular restaurant set in a beautifully restored historic building on High Street. The inviting atmosphere is enhanced by antique timber and stained glass windows, with local folk crafts adorning the walls.

Transportation Around Killarney

Rental Car

The best way to explore Killarney and its surroundings is by renting a car. I recommend using Discover Cars, which compares local and international rental companies to help you find the best price. Renting a car provides the flexibility to explore remote areas and avoid large tour groups.

Killarney Shuttle Bus

If you prefer not to drive, the Killarney Shuttle Bus offers a convenient hop-on-hop-off service that takes you to all the main attractions in Killarney National Park.

Taxi

While there are local taxi services, I suggest using them as a last resort due to their higher costs.

Jaunting Carts

During your time in Killarney, keep an eye out for horse-drawn carriages known as “jaunting carts” or “pony-and-trap.” This charming mode of transportation offers a unique way to explore the National Park, with options for short rides or longer tours with various stops.
