Lough Corrib: Ireland’s Majestic Waterway

The Natural Beauty and Geography of Lough Corrib

Lough Corrib, the largest lake in the Republic of Ireland, is a breathtaking expanse of water that stretches across Counties Galway and Mayo. Spanning approximately 176 square kilometers (68 square miles), it is a haven of natural beauty, biodiversity, and historical intrigue.

The lake is divided into two sections—the upper and lower Corrib—separated by a narrowing near Oughterard. The upper section, located in County Mayo, is wilder and more rugged, featuring islands, boglands, and remote shorelines. In contrast, the lower section, closer to Galway City, is more accessible and known for its serene waters and picturesque surroundings.

The lake is home to over 1,300 islands, many of which are steeped in history and legend. Some of the most famous include:

Remains of prehistoric settlements, crannógs (artificial islands), and burial sites can still be found around its shores and islands.

2. The Legend of Oisín and Niamh
One of the most famous myths linked to Lough Corrib is the tale of Oisín and Niamh.

According to legend, Oisín rode across the waters of Lough Corrib on a magical horse, leaving behind the mortal world for the enchanted realm of eternal youth.

During the medieval period, Lough Corrib was a strategic location for trade and defense. Several castles and fortresses were built along its shores, including:

The island also features a remarkable gravestone, believed to mark the burial site of St. Patrick’s nephew, Lugna.

5. The Ghosts and Hauntings of the Lake
With its long history, it’s no surprise that Lough Corrib has its fair share of ghostly tales.
