Overview
The Glenshesk River is a modest but captivating watercourse that threads its way through the Glenshesk valley – one of the famed nine Glens of Antrim – before spilling into the Atlantic at Ballycastle Bay. Shaped by the last Ice Age, the glen’s steep sides are cloaked in mixed woodland, open fields and a patchwork of stone walls that speak of a long agricultural tradition. The river itself is shallow and brown‑tinged near its mouth, a characteristic that adds a rustic charm to the surrounding beach and mini‑park where information boards tell the story of the area.
History
The valley surrounding the Glenshesk River is steeped in centuries of conflict and culture. At the foot of the glen lie the ruins of the Franciscan Friary of Bunamargy, founded in 1485 by the local chieftain Rory MacQuillan. The friary was later set alight by English forces under Sir William Stanley in 1584, a reminder of the turbulent Tudor wars that scarred the region. Standing stones dot the landscape, marking ancient burial sites of clan warriors who fell in battles that pitted the MacDonnells, the MacQuillans and the McNeills against one another.
The 19th‑century Glenshesk Bridge, an early Victorian stone arch built by William Bald in 1846, is a local landmark. Known locally as the “Big Bridge”, it is the only bridge in the Antrim glens that bears carvings on both faces, hinting at the craftsmanship of Charles Lanyon’s design studio. During the World Wars the glen contributed to the war effort: men stayed on the farms to keep food supplies flowing, and the area witnessed two dramatic aircraft crashes in 1941 and 1943, the remnants of which are still recounted in local oral history.
Flora & Fauna
The mixed woodland along the river supports a variety of native trees such as oak, ash and hazel. In spring the glen is carpeted with bluebells and primroses, while summer brings heather on the higher slopes. Birdwatchers can spot kingfishers darting over the shallow pools, while the banks are a favourite haunt for mallards, greylag geese and, on quieter days, otters. The river’s clear sections support brown trout, making occasional angling a low‑key activity.
What to See & Do
- Stroll the Riverbank – A well‑maintained footpath follows the river from the mini‑park at the mouth up through the glen. Along the way you’ll cross several low‑level bridges, including a pedestrian footbridge that offers a perfect photo‑op of the river’s gentle flow and the mallards that often paddle nearby.
- Explore Bonamargy Friary – Just a short walk from the river’s lower reaches, the friary ruins provide a tangible link to 15th‑century monastic life. The stone walls and vaulted arches are especially atmospheric at sunrise.
- Visit the Glenshesk Bridge – Pause on the “Big Bridge” to admire the dual carvings and imagine the engineers who built it during the Irish Famine, a period of massive civil‑engineering activity.
- Wildlife Watching – The river’s shallow pools attract mallards, kingfishers and occasional otters. Anglers can be seen casting from the banks, especially near the mini‑park where a few locals fish for trout.
- Coastal Views – At high tide the river meets the sea in a dramatic estuary, framed by the cliffs of Fair Head in the distance. From the beach you can also see the ferry terminal for Rathlin Island, making a quick detour to the island’s historic cave possible.
- Historical Walks – Follow the Glenshesk Scenic Route signposted from the T‑junction near the Bonamargy Friary. The route weaves past ancient Breen Wood, St Patrick’s Church and its round tower, and offers glimpses of the WW2 crash sites on Drumacullin and Cool Brae, marked by interpretive panels.
Practical Information
Getting there – The easiest public‑transport link is the train from Belfast Lanyon Place to Portrush, changing at Coleraine or Ballymena. From Ballymena, Bus 217 runs to Ballycastle; note that no service operates between 11:30 am and 2:45 pm, so plan your arrival outside that window. An alternative is Bus 402 from Coleraine, marketed as the “Tourist Rambler”, which drops passengers directly in Ballycastle.
Parking – Free parking is available on the promenade adjacent to the river’s mouth and near the mini‑park. The car park is a short walk from the footbridges and the beach, making it convenient for families and cyclists.
Admission – There is no entry fee to walk along the river or to visit the surrounding historic sites; all attractions are free to the public.
Facilities – The mini‑park beside the river provides benches, information boards and a small shelter. Public restrooms are located near the beach promenade. Several cafés and the Kebab King takeaway on the main street of Ballycastle offer refreshments for a quick bite after your walk.
Seasonal notes – The river’s estuary is most photogenic at high tide, when the water rushes over the sandbars and the cliffs of Fair Head become visible on clear days. The footbridges are open year‑round, and the historic markers are maintained by the Glens of Antrim Historical Society.
Accessibility – The promenade and the main footbridge at the river mouth are level and suitable for wheelchair users. Some of the narrower, older stone bridges have steps and may be challenging for those with limited mobility.
