Drumcliff Bay and River Highlights

📍 Drumcliff Bay, Sligo

🏛️ Attraction

Last updated: 28 April 2026

Overview

Drumcliff Bay, often called the Drumcliff Estuary, marks the point where the Drumcliff River (traditionally the Codnach) spills into the shallow waters of Sligo Bay. Framed to the west by the low sand‑dune spit at Lower Rosses and backed by the iconic silhouette of Ben Bulben, the estuary is a patchwork of salt‑marsh, mudflats, dunes and sandy beaches such as Lissadell Strand. At low tide the mudflats become a vast, reflective carpet, while the higher shore offers sweeping views of the Atlantic horizon.

The river itself runs eight kilometres north of Sligo town, draining Glencar Lake before crossing the N15 at a low‑lying bridge. Downstream the waterway is designated as a fly‑only stretch, renowned for salmon, sea‑trout and brown trout.

History & Background

The estuary’s ecological value is recognised at European level: it is a Special Protection Area (SPA) under the EU Birds Directive and part of the Cummeen Strand/Drumcliff Bay Special Area of Conservation (SAC). Volunteers from BirdWatch Ireland monitor wintering flocks of barnacle and brent geese, while the adjacent Ballygilgan Nature Reserve – the famed “goose field” – provides safe grazing for these birds.

The river’s name, Codnach, means “placid or even‑tempered river”. Early Irish annals record a legendary battle on its banks in A.M. 3656 (1538 BC), and the Dinnsenchus poem recalls wicker‑framed boats once built here. Medieval historian Mac Firbisigh mentions a now‑lost “Fort of Codhnach”. Over the centuries the waterway has witnessed monastic settlements and the passage of poets, linking it intimately with the village of Drumcliff, home to St Columba’s 6th‑century monastery and the burial place of W.B. Yeats.

Wildlife & Conservation

The mudflats and surrounding dunes support a rich tapestry of wildlife. In winter, flocks of barnacle and brent geese dominate the scene; spring and autumn migrations bring waders such as oystercatchers, curlews and redshanks. BirdWatch Ireland’s volunteers conduct regular counts, contributing data to the SPA monitoring programme. The dune system at Lower Rosses hosts specialised flora including marram grass, sea lavender and the rare sea holly.

What to See & Do

Birdwatching & Tide‑Revealed Mudflats

  • Winter brings massive flocks of barnacle and brent geese to the mudflats and Ballygilgan. Spring and autumn migrations add waders and gulls. Binoculars and a field guide are essential.
  • Check local tide tables and walk the exposed mudflats at low tide for striking reflections and photographic opportunities, especially with Ben Bulben on the horizon.

Sand‑Dune Walks & Beaches

  • The dune system at Lower Rosses offers gentle undulating paths, viewpoints over the estuary, and specialised flora such as marram grass and sea lavender.
  • Lissadell Strand provides a wide, sandy beach ideal for leisurely strolls, picnics, and, when conditions are calm, a quick dip.

Angling

  • The Drumcliff River is a premier salmon and sea‑trout fishery. Seasons (all dates inclusive):
SpeciesSeason
Salmon1 Feb – 30 Sep
Sea trout1 Feb – 12 Oct
Brown trout15 Feb – 12 Oct
  • Upstream of the N15 bridge any legal method may be used; downstream is fly‑only. The “Fly Pools” just beyond the bridge are famed for sea‑trout during the Mayfly hatch, with natural flies such as Cahill, Green Peter and Mayfly proving effective. Record catches include sea‑trout over 1½ lb and a 22‑lb salmon.

Cycling & Events

Drumcliff Bay forms part of County Sligo’s popular Bike Week routes, offering a relatively flat, traffic‑light‑free circuit that showcases the estuary, dunes and coastal scenery. Cyclists can start from the Lower Rosses car park, follow the riverside trail to Lissadell Strand and return via the Benbulben Forest Walk. Local bike‑hire shops in Sligo town often include this loop in their suggested itineraries during the annual Bike Week celebrations (see the county’s event calendar for exact dates).
