Cushnavally Lake – A Hidden Gem in the Gap of Dunloe

Overview

Cushnavally Lake sits in the heart of the Gap of Dunloe, a narrow U‑shaped valley that separates the towering MacGillycuddy’s Reeks to the west from the Purple Mountain Group to the east. It is the third of the five corrie lakes that punctuate the valley – Coosaun Lough, Black Lake, Cushnavally Lake, Auger Lake and Black Lough – all linked by the River Loe. The lake’s surface mirrors the rugged red‑sandstone cliffs that line the road, creating a picture‑perfect spot for anyone travelling the Ring of Kerry or exploring Killarney National Park.

History & Geology

The entire Gap of Dunloe, including Cushnavally Lake, was carved during the last ice age, roughly 25,000 years ago. A massive glacier that once filled the Black Valley broke through the head of the Gap, gouging out a deep, U‑shaped trench in the ancient Old Red Sandstone. As the ice retreated, melt‑water filled the depressions left behind, forming the chain of lakes we see today. The River Loe, which gives the Gap its name, continues to flow through Cushnavally Lake, linking it to its neighbours and eventually draining into the Lakes of Killarney.

The name “Dunloe” derives from the Irish Dún Lóich – “the fort of Lóich” – a reference to an ancient chieftain whose legend is recorded in the Annals of Clonmacnois. While the lake itself does not host any historic ruins, the surrounding landscape is dotted with stone bridges and the famous “Turnpike” boulder, a natural gate‑post that frames the road as it winds past the water.

What to See & Do

Scenic Views

Cushnavally Lake is a natural viewpoint. From the public road that runs the length of the Gap, you can pull over at the designated lay‑by near the lake and soak in the contrast between the dark, glassy water and the bright, craggy peaks of the Reeks. Photographers love the early‑morning light that paints the mountains in gold, while the lake’s stillness often reflects a perfect sky.

Walking & Hiking

The lake is easily reached on foot from Kate Kearney’s Cottage, the historic 150‑year‑old family‑run bar and craft shop that marks the northern entrance to the Gap. The short walk from the cottage to the lake is about 1 km (0.6 mi) each way and takes roughly 15‑20 minutes. For those seeking a longer trek, the full Gap walk (approximately 11 km) passes directly beside Cushnavally Lake, offering a chance to pause, stretch, and enjoy the tranquil waters before continuing toward the Head of the Gap.

Jaunting‑Car & Boat Experiences

If you prefer a more relaxed way to experience the lake, hop on a traditional jaunting car (horse‑drawn carriage) at Kate Kearney’s Cottage. The carriage follows the same road, giving you uninterrupted views of Cushnavally Lake and the surrounding cliffs. Many guided tours combine the jaunting‑car ride with a boat transfer from Lord Brandon’s Cottage back to Ross Castle in Killarney, allowing you to glide across the River Loe and see the lake from a different perspective.

Wildlife & Photography

Sheep often graze on the low‑lying pastures that fringe the lake, and the River Loe attracts a variety of waterfowl, including swans and ducks. While the lake itself is not a designated fishing spot, the surrounding waterway supports a healthy trout population, making it a quiet spot for anglers who join a guided boat tour.

Practical Information

Shuttle Schedule (2026 data)

All shuttle times should be confirmed with the local operator before travel, as seasonal adjustments are possible.

Getting There

The most convenient starting point is Kate Kearney’s Cottage (address: Dunloe Upper, County Kerry). From Killarney, follow the N72 west for about 12 km; the turn‑off to the Gap is clearly sign‑posted. If you are driving, aim to arrive early (before 07:30 am in summer) to avoid the peak of tourist traffic and to secure a parking space.

For those without a car, a combination of a bus to Killarney and a guided tour (many of which are listed on GetYourGuide) will drop you at Kate Kearney’s Cottage, where you can join a jaunting‑car or a boat excursion.

Accessibility

The lakeside lay‑by and the short walk to Cushnavally Lake are on relatively even ground, making them accessible for visitors with limited mobility. However, the road itself is narrow and winding, and the jaunting‑car ride involves occasional dismounts on steep sections, which may be challenging for some passengers.

Best Time to Visit

Mid‑summer offers the longest daylight hours, but early morning (sunrise) provides the most dramatic light on the water and fewer crowds. Autumn brings a palette of gold and amber across the surrounding hills, creating a different but equally striking atmosphere.

Photography Tips

• Golden hour – Arrive 30‑45 minutes before sunrise or after sunset for warm, soft light that enhances the lake’s mirror‑like surface.
• Reflections – Calm days give the best mirror effect; a light wind can add texture without destroying the reflection.
• Composition – Use the Turnpike boulder or the stone bridge as foreground elements to add depth.
• Equipment – A polarising filter helps reduce glare and intensifies the sky’s colour.

Nearby Attractions

While you’re in the Gap, consider a short detour to Ross Castle on the shores of Lough Leane, or stop in Beaufort, the gateway village to the Reeks and the Ring of Kerry. Both are easily reachable by the same shuttle services that serve the Gap.

Seasonal Highlights

• Autumn colours – Late September to early October sees the surrounding hills turn amber and copper, offering a striking contrast to the lake’s dark water.
• Spring wildflowers – The low‑lying pastures blossom with yellow and white wildflowers, adding subtle colour to the landscape.

In Summary

Cushnavally Lake may be modest in size, but its position within the dramatic Gap of Dunloe makes it a highlight for walkers, photographers, and anyone seeking a quiet moment amid Ireland’s most iconic mountain scenery. With free parking, easy walking routes, and a variety of guided‑tour options, the lake is readily accessible while still feeling like a secluded alpine tarn. Whether you pause for a brief photo, enjoy a leisurely jaunting‑car ride, or glide past on a boat, Cushnavally Lake offers a quintessential slice of Kerry’s natural beauty.
