Constructed to connect Mulranny village and the railway system to the shore, the Victorian Causeway spans Trawoughter Bay. Today, it provides visitors with direct access to a pristine coastal landscape featuring a Blue Flag beach, a rare machair plain, and the ecologically famous Mulranny Saltmarsh.
The Historic Causeway Walk Review
Walking along the causeway offers uninterrupted, 360-degree views across Clew Bay towards Croagh Patrick. At low tide, the saltmarsh drains into intricate tidal channels, exposing rich mudflats that serve as a crucial feeding habitat for native and migrating waterfowl.
Why Visit the Causeway & Saltmarsh?
- Historic Architecture: Constructed to bridge the village directly over the bay.
- International Bird Habitat: Wintering ground for Brent Geese, Curlews, and Oystercatchers.
- Varied Terrains: Passes through tidal channels, storm beaches, and machair dunes.
- Direct Greenway Access: Easily linkable into the Great Western Greenway and Lookout Hill loop.
Ecology & Seasonal Wildlife
The Mulranny Saltmarsh is noted for its specialized channel network and heavily grazed coastal flora. During the autumn and winter months, the area hosts a significant portion of Ireland's wintering Brent Geese population alongside Grey Plovers, Godwits, Dunlins, and Terns.
