Overview
Lough Nafooey (also written Loch Na Fooey) lies in the heart of Connemara, County Galway, just 11 km from the village of Leenane and a short drive from the Mayo village of Finny. The lake stretches roughly 2.5 miles (4 km) long and 0.5 miles (0.8 km) wide, forming a striking rectangular basin framed by the rugged Maumturk Mountains to the south and the Partry Mountains to the north. A small sandy beach at the western end provides a rare freshwater shoreline, while a tiny funnel‑shaped island sits near the south‑eastern shore.
The lake is fed by several streams, the most notable being the River Fooey, which rises on the slopes of Devil’s Mother mountain, and the Finny River, which drains the lake’s south‑eastern corner into Lough Mask. The surrounding valley is a classic example of a glacially carved landscape, with steep sides that plunge down to the water’s edge.
History & Geology
Although today Lough Nafooey appears as a tranquil lake, the ground beneath tells a dramatic story. The area is part of the ancient “Finny volcano” system, a volcanic centre that was active around 490 million years ago during the Ordovician period. While the volcano itself has long since vanished, remnants of its activity survive as pillow lavas, breccia and other volcanic rocks scattered across the hillsides. These formations link the region to a wider network of extinct volcanoes that once dotted Ireland, Europe and even parts of North America.
Local folklore adds a mythic layer to the lake’s identity. Legends speak of An Capall Uisce, the Water Horse, a Celtic spirit said to roam the waters at dusk. Whether you believe in the creature or not, the tale adds an enchanting aura to evening walks along the shore.
What to See & Do
Walking and Hiking
The Lough Nafooey perimeter is criss‑crossed by sign‑posted trails suitable for all abilities. A gentle stroll along the western sandy shore offers panoramic lake views and easy access for families, and dogs on a leash are welcome on most of the paths. More ambitious walkers can venture onto the surrounding hills, where the volcanic geology becomes visible in exposed rock faces and the occasional pillow lava outcrop. The route that circles the lake also provides striking vistas of Killary Harbour – Ireland’s only fjord – and the distant peaks of the Maumturks.
Fishing
Anglers are drawn to the lake’s healthy stocks of wild brown trout and pike. Fishing is permitted with a licence, which can be obtained in the nearby villages of Leenane and Finny. The clear, cold waters make for rewarding catches, especially for those who enjoy fly‑fishing in a remote setting.
Boating & Swimming
The western beach is one of the few freshwater beaches in Ireland, offering a safe spot for a quick dip on a sunny day. Small boats are available for hire from a handful of holiday cottages dotted around the shore, allowing visitors to explore the lake’s calm interior at their own pace.
Road Cycling
Lough Nafooey is a magnet for road cyclists, with seven documented routes ranging from moderate loops to challenging climbs. Highlights include:
| Route | Distance | Approx. Time | Elevation Gain | Difficulty |
|---|---|---|---|---|
| Clonbur Wood & Cornamona Loop | 28.8 mi (46 km) | 2 h 05 m | 1,150 ft (350 m) | Moderate |
| View of Killary Fjord – Doolough Valley Loop | 35.6 mi (57 km) | 2 h 21 m | 1,200 ft (365 m) | Moderate |
| Sheeffry Pass Loop | 63.5 mi (102 km) | 4 h 50 m | 3,525 ft (1,075 m) | Hard |
| Lough Mask Viewpoint – Lough Nafooey Loop | 41.7 mi (67 km) | 3 h 23 m | 2,550 ft (777 m) | Moderate |
These routes hug the lake’s shoreline, climb into the surrounding passes, and often provide sweeping views of Killary Fjord, the Partry Mountains, and the distant Atlantic coastline. Cyclists can start from designated car parks such as the Aasleagh waterfall car park, and many routes are well‑paved, making them accessible to riders with a moderate level of fitness.
Cultural Highlights
The nearby villages of Leenane, Finny and Clonbur offer traditional Irish pubs, craft shops and modest accommodation options. Leenane, perched at the head of Killary Harbour, is especially popular for its scenic harbour and easy access to the lake’s southern edge.
