Doolough Valley

📍 Doolough Valley, Mayo

🏛️ Attraction

Last updated: 4 March 2026

Overview

Doolough Valley stretches between the towering Mweelrea Mountains to the west and the Sheeffry Hills to the east, cradling three dark lakes – Fin Lough, Doo Lough and Glenullin Lough. The valley forms part of the Wild Atlantic Way and is best experienced by car or bicycle, following the winding R335 from Leenane to Louisburgh. The road is relatively wide, allowing two cars to pass comfortably, and offers numerous pull‑over spots for photography, picnics or a short walk.

History

The valley is most famous for the Doolough Tragedy of March 1849, when hundreds of starving residents from Louisburgh set out for the Delphi Lodge in search of famine relief. Denied assistance, many perished on the 12‑mile trek back through the harsh winter landscape. A simple stone cross – the Doolough Famine Memorial – stands beside a small car park on the lakeside road, bearing the inscription “The Hungry Poor Who Walked Here in 1849 and Walk The Third World Today” and a quote from Mahatma Gandhi. The memorial provides a quiet place for reflection and is a focal point for an annual remembrance walk.

What to See & Do

Aasleagh Waterfalls

Just off the Leenane‑Westport road, the Aasleagh Waterfalls drop into the River Erriff. A single‑car accessibility parking space sits at the trailhead; from there a short, un‑paved walk leads to a viewpoint where salmon may be seen spawning in season. The route forms part of the Western Way, so walkers can continue along the river for a longer trek.

Killary Fjord

Ireland’s only fjord, Killary Fjord, borders the valley’s northern edge. Visitors can enjoy a 90‑minute boat cruise (GetYourGuide) or walk the historic “Killary Famine Route”, a 14 km loop that follows the 19th‑century Green Road.

Doo Lough

The dark waters of Doo Lough reflect the surrounding peaks and provide a tranquil base for kayaking, stand‑up paddleboarding and fishing. Anglers can target brown trout and salmon, but must obtain the appropriate permits from the Delphi Fishery (Delphi Lodge). A stone beach on the lake’s northern shore offers easy launch access.

Hiking & Walking

  • Mweelrea from Doo Lough – a demanding ascent to Connacht’s highest peak (814 m). Suitable for experienced hikers.
  • Ben Bury – a slightly lower summit (795 m) with excellent views of Killary Harbour.
  • Barrclashcame & Tievummera Loop – a 17 km moderate loop that traverses grassy slopes and rocky outcrops.
  • Delphi Forest Walk – an easy, family‑friendly trail through mixed woodland, ideal for a leisurely stroll.
  • Sheeffry Mountains Loop – a 13 km circuit offering sweeping valley panoramas and fewer crowds.

Cultural Extras

  • Lost Valley Tour – a pre‑booked 3‑hour guided walk on a private working farm, costing €25 per adult and €10 per child (Lost Valley website).
  • Silver Strand Beach – a secluded golden‑sand beach 40 minutes from the memorial, perfect for a quiet dip.
  • Clew Bay Archaeological Trail – a heritage trail with neolithic tombs and Bronze Age monuments, accessible from the nearby heritage centre.
  • Kylemore Abbey – a neo‑Gothic estate 30 km south of the valley, reachable via a short detour into Connemara.

The drive is well‑signed; the Wild Atlantic Way marker appears at the valley entrance. Parking is free at several pull‑over spots, including a larger area near the northern end of Doo Lough and a small car park beside the famine memorial.

Accessibility

Aasleagh Waterfalls offers a single‑car accessible parking space, but the walking path to the falls is unpaved and lacks a dedicated pedestrian walkway until the bridge. The main valley road is suitable for standard vehicles, and the drive itself is wheelchair‑friendly as long as visitors remain in the car.

Seasonal Considerations

The valley is accessible year‑round. Winter can bring snow on the higher passes, so drivers should check local weather reports before attempting the Mweelrea ascent. Boat tours on Killary Fjord operate seasonally, with more frequent departures in summer.

Whether you’re seeking dramatic scenery, a poignant slice of history, or a base for outdoor adventure, Doolough Valley delivers a memorable slice of western Ireland that remains largely untouched by the crowds.
