Overview
Errisbeg Hill (Irish: Iorras Beag, “small peninsula”) is a modest‑sized Marilyn and Hewitt situated just outside the fishing village of Roundstone in Connemara, County Galway. At roughly 300 m (Wikipedia) – or 280 m according to some local tourism sites – the hill dominates the surrounding bogland and coastline, offering one of the most accessible high‑point views on the Wild Atlantic Way. From the summit you can spot the Roundstone Bog, Dog’s Bay, the Twelve Bens, the Aran Islands on a clear day, and the endless Atlantic horizon.
The hill sits on a granite‑based substrate of hornblende metagabbros and metanorites, giving the landscape its characteristic rugged texture. Its prominence of 275 m makes it the most westerly summit in the South Connemara area and a useful navigation point for local fishermen.
History & Landscape
The name Iorras Beag simply describes the hill’s shape – a small peninsula jutting into the sea. In 1684 the 17th‑century historian Roderic O’Flaherty wrote of the hill as a “second place discovered by marriners … over which is Irrosbeg hill, the second place discovered by marriners after the Twelve Bens”. Historically the hill has served as a grazing area for sheep and a landmark for vessels entering Roundstone harbour. In recent decades it has become a favourite waypoint for walkers seeking a taste of Connemara’s wild beauty without the commitment of a multi‑day trek.
Geology
Errisbeg is formed from hornblende‑rich metagabbro, a hard, dark igneous rock that weathers to thin, nutrient‑poor soils. This geology underpins the blanket bogs and heathland that blanket the slopes, and contributes to the hill’s sharp, exposed ridgeline that offers unobstructed views in all directions.
Flora, Fauna & Wildlife
Late spring and early summer bring a carpet of heather, gorse and alpine‑type wildflowers such as bell‑heather, crowberry and the rare Mackay’s heath. The hill is also a habitat for St Dabeoc’s heath, another locally scarce plant. Sheep are a constant presence, and raptors – buzzards, kestrels and occasionally peregrine falcons – can be seen circling the ridge. From the summit you may also spot seals playing in the waters off Dog’s Bay on a clear day.
The Errisbeg Loop Walk
The most popular route is a roughly 7 km (4‑5 mi) loop that starts at the road junction just off the R341, a short walk from the centre of Roundstone. The trailhead is marked by a small free car park and a gate at the end of the narrow road that runs past O’Dowd’s Seafood Bar. From the gate, follow the sheep‑track uphill, veering left to avoid the wetter bog sections. The ascent gains about 450 m and passes a mixture of open hillside, wet blanket bog, and a short stretch of surfaced minor road before reaching the cairn‑topped summit.
The walk is rated moderate to difficult – the bog can be slippery after rain and the route is unmarked in places, so a basic map or GPS (coordinates 53.395050, -9.958932) is advisable. Most walkers complete the loop in 3–5 hours depending on fitness and weather.
Mixed‑Mode Adventure
Cyclists can incorporate a 12 km coastal segment from the estate of Ballynahinch Castle to the base of the hill, then continue on foot for the final 5 km to the summit. This option is popular with those who want to combine sea‑views on a bike with a hill‑top finish.
