Roe Estuary – waders on Lough Foyle

📍 Aghanloo, Londonderry

🏛️ Attraction

Last updated: 20 June 2026

Overview

Roe Estuary is a reserve for watching, not walking. It sits on the south-east bank of Lough Foyle where the River Roe meets it, about 6km north of Limavady in County Londonderry, and the draw is the intertidal mud, salt-marsh and eel-grass that feed thousands of waders, ducks, swans and geese on their winter passage. The best of it can be seen from the car park at high tide without setting foot on the shore. Below the surface the mud holds lugworms, ragworms, shrimps, periwinkles and dense mussel beds – the larder that brings the birds in.

Background

The estuary was designated a nature reserve in the 1990s and is managed by the Northern Ireland Environment Agency. It is part of the wider Lough Foyle system, a major stop-over for birds moving between the Atlantic and inland wetlands. The Coleraine–Portrush railway still crosses the estuary on a low bridge, and the strip of salt-marsh alongside the line is an unusual habitat for the area. Crossing the railway or the bridge is prohibited.

When to come

The reserve is a winter site first and foremost. From November to March curlew, bar-tailed godwit, turnstone and brent goose gather in the largest numbers, and a rising tide pushes them onto the mud in front of the car park. Spring brings breeding lapwing and the odd nesting redshank; summer is quieter for birds, though otters are seen more often then, hunting crabs in the shallow pools. Autumn sees big flocks of brent goose building up again. Come early: the curlew calling across the marsh at dawn is the thing people remember.

Birdwatching

The mud-flats are the reason to be here. Species recorded regularly include:

  • Curlew (Numenius arquata)
  • Lapwing (Vanellus vanellus), with its tumbling spring display flights
  • Turnstone (Arenaria interpres)
  • Bar-tailed godwit (Limosa lapponica)
  • Brent goose (Branta bernicla)

High tide concentrates the flocks; low tide spreads them across mud that is too soft and too far to approach safely. Bring binoculars or a scope – without them you will see distant specks.

Fishing and otters

Salmon and eels move through the estuary between the River Roe and Lough Foyle, and anglers take silver eels, flounder, bass, sea trout and the occasional mullet, using size 1 to 1/0 hooks baited with worm, crab or fish strip. Otters work the shallow pools around high tide, when the receding water makes them easier to pick out.

Walking

There are no formal paths on the reserve. The flat coastal walk that forms part of the Lough Foyle Trail passes the estuary, with access points at Station Road (Ballykelly), Carse Road (Broharris), Carrowclare Road (Ballymacran) and Shore Avenue (Myroe). Be honest with yourself about the ground: the shore is soft mud and can be dangerous at low tide. The site manager’s advice is plain – stay within the car-park viewing area at high tide, check tide tables before you go, and wear sturdy footwear.

The calm tidal stretch of the Roe near the estuary draws paddleboarders and kayakers in summer. Launch from the car-park area at high tide for the safest water.

Conservation status

Roe Estuary is part of the Lough Foyle Ramsar site, designated in 1999 as a wetland of international importance, which takes in the estuaries of the Foyle, Faughan and Roe. It is also a Special Protection Area under the EU Birds Directive, recognising its value for wintering and migratory waders. Dogs are not permitted on the reserve, to protect the bird roosts; take all litter home and keep off the salt-marsh vegetation.

Getting there

The estuary lies off the A2 north of Limavady. From Derry follow the A2 east for about 30km; Lough Foyle Trail signage directs you to the car park at the end of Carrowclare Road, off the B69 Seacoast Road. Public transport is limited – the nearest station is Bellarena on the Coleraine–Portrush line, a short taxi from the reserve, and local buses between Limavady and Derry stop at the A2 junction near the trailhead.
