Lough Gill – A Poet’s Lake in Sligo

Overview

Lough Gill (Irish: Loch Gile) is a freshwater lake of limestone origin, stretching almost 8 km from east to west and about 2 km across. The lake lies mainly in County Sligo with a small portion in County Leitrim, and drains westward into the River Garavogue near Sligo town. Its calm, mineral‑rich waters are framed by mixed oak, rowan and willow woodlands, the wooded hills of Slieve Killery and Slieve Daean, and a chain of roughly twenty small islands. The setting inspired William Butler Yeats’s poem “The Lake Isle of Innisfree” and continues to attract walkers, birdwatchers and literary pilgrims.

History & Mythology

Archaeological evidence shows that the surrounding woodlands have been managed since at least 4 600 BC, with Scots pine dominating until 3 400 BC. The area was home to the Cálraighe tribe in the early historic era, and later became the seat of the Uí Ruairc clan. In the 17th century the plantation‑era fortified house that is now Parke’s Castle was erected on the northern shore, replacing an earlier tower house of the O’Rourke family. The lake’s name is linked to an ancient myth recorded in the Metrical Dinnsenchus: a maiden called Gile drowned in a spring, the tears of her nurse flooding the valley and forming the lake, which was thereafter called Loch Gile.

The islands hold further history. Church Island bears the ruins of a 6th‑century abbey founded by Saint Lommán of Trim, while Cottage Island (also known as Beezie’s Island) was inhabited until 1949. The lake’s micro‑climate supports rare flora such as the Mediterranean strawberry tree (Arbutus unedo) – the world’s northernmost specimens – and orchid‑rich calcareous grassland, earning Lough Gill SAC status under the EU Habitats Directive.

What to See & Do

Walks and Woodlands

• Hazelwood Forest (5 km south of Sligo) offers several short trails, the longest about one hour, with viewpoints over Church Island, Cottage Island and the full lake expanse.
• Slish Wood on the southern shore provides a 3 km rugged hillside track that rewards hikers with sweeping lake panoramas; a car park is available at the trailhead.
• Dooney Rock on the western edge is a short 30‑minute loop that culminates in a rocky promontory overlooking the lake, Benbulben and Knocknarea.

Islands

• Lake Isle of Innisfree – the uninhabited island celebrated by Yeats – can be viewed from the shore or on a boat tour.
• Church Island and Cottage Island are visible from Hazelwood and Parke’s Castle respectively.
• Beezie’s Island offers a glimpse of the lake’s quieter corners.

Heritage Sites

• Parke’s Castle (County Leitrim) – a restored 17th‑century fortified house – dominates the northern shoreline. Its silhouette at sunset is a favourite photograph.
• Church Island Abbey ruins (6th century) and the Tobernalt Holy Well (a Celtic‑Christian pilgrimage site) lie on the lake’s western fringe.

Wildlife

The lake is a Special Area of Conservation for its alluvial forest and orchid‑rich grassland. Birdwatchers can spot kingfishers, common terns and wintering waterfowl. The waters host sea, river and brook lamprey, Atlantic salmon, white‑clawed crayfish and otter. Spring brings an early run of salmon, and a small colony of common terns breeds on the islands.

Water‑Based Activities

• Boat tours depart from Sligo town and from the foot of Parke’s Castle. The Rose of Innisfree waterbus runs daily in summer, offering an hour‑long cruise that includes a guided visit to the castle.
• Kayak tours are available through Sligo Kayak Tours, supplying equipment and instruction for all ability levels.
• Swimming and paddle‑boarding are permitted in the lake’s clear, mineral‑rich water; the Lough Gill 10 km charity swim takes place each summer.
