Lookout Hill

Overview

Lookout Hill Loop is one of the highlights of the Wild Atlantic Way in County Mayo. Starting and ending at the picturesque Mulranny Pier, the 5.9 km (approximately 6 km) circuit climbs gently to a summit of about 100 m, delivering sweeping vistas of Bellacragher Bay to the north and the drumlin‑strewn Clew Bay to the south, with the iconic silhouette of Croagh Patrick on the horizon. The trail is marked with red arrows and is suitable for families with older children, though the terrain includes boggy sections and a few short ascents that demand sturdy trekking shoes.

History & Background

The route follows the historic Mulranny Causeway, a stone‑built causeway erected in 1889 to connect the village with the Mulranny Park Hotel and the surrounding marine environment. This engineering feat opened up access to a Blue Flag beach, the Rosmurrevagh Machair dune‑grassland, and the Mulranny Salt Marsh – all now protected as part of three European‑designated conservation areas.

A bronze sculpture of a suitcase‑shaped seat, installed on the Great Western Greenway near the loop, commemorates the emigration of Achill men in the 19th century and adds a cultural touchpoint for walkers.

Flora & Fauna

• Mediterranean‑type heather – Ireland’s only swathe of this rare heather blankets the upper slopes, turning a vivid purple in late summer.
• Sea thrift – The salt‑marsh fringe bursts into pink during spring and early summer, providing colour and nectar for insects.
• Birdlife – The Mulranny Salt Marsh and surrounding machair attract wading birds such as oystercatchers, curlews and wintering geese.
• Wild Irish goats – A small herd roams the woodland sections and can often be spotted near the summit.
• Marine life – In the tidal pools of Trawoughter Bay you may see jellyfish with distinctive purple rings.

What to See & Do

• Panoramic vistas – Photograph Bellacragher Bay, the islands of Clew Bay and the towering Croagh Patrick.
• Historic causeway – Walk across the 1889 stone bridge spanning Trawoughter Bay.
• Picnic spot – A wooden table near the summit offers a perfect rest point with sea views.
• Greenway link – The loop intersects the Great Western Greenway, allowing cyclists to join for part of the walk.

Nearby Attractions

Practical Information

The trail is open year‑round and free to access. A downloadable PDF map is provided by the National Trails Office and can be accessed here: Mulranny Lookout Hill Loop Map.pdf.

Because the trail traverses boggy ground and a short stretch of woodland that can become water‑logged, walkers should wear waterproof trekking shoes and be prepared for occasional wet footing. The “no dogs” rule helps protect the sensitive heather and bird habitats.
