Overview
The River Main – often spelled Maine – is a modest but charismatic river in County Antrim, Northern Ireland. Its source lies high in the Glens of Antrim, a landscape of steep valleys and blanket bogs that has inspired poets and hikers for centuries. From its headwaters the river flows north‑west through the villages of Cullybackey and Randalstown, before entering the expansive Lough Neagh, the island’s largest freshwater lake. The river ultimately joins the Lower Bann and reaches the North Channel.
Geography & Hydrology
- Length: approximately 55 km (34 mi) 【Wikipedia】
- Average discharge: 15.4 m³ s⁻¹ 【Wikipedia】
- Catchment area: about 400 km²
- Main tributaries: left‑hand Kellswater and Braid River 【Wikipedia】
- Course: rises in the Glens of Antrim, passes through Ballymena, Cullybackey and Randalstown, and empties into Lough Neagh at the townland of Slaght Bridge.
- River name: Irish An Mhean (or An Mhaighin), meaning “river of the plain”.
The river’s clear, oxygen‑rich waters support a late‑season run of Atlantic salmon and a healthy population of sea‑trout, making it a key tributary for Lough Neagh’s fishery.
History & Background
The name Maine (Irish: An Mhean) reflects the river’s ancient Gaelic roots, literally “river of the plain”. Historically the waterway shaped settlement patterns in the Antrim interior; villages grew around mills and fords that harnessed its steady flow. In the 20th century the river gained a political footnote when former Northern Ireland Prime Minister Terence O’Neill was ennobled as Baron O’Neill of the Maine, underscoring its symbolic place in regional identity.
Environmental Impacts
A long‑term study of the River Main’s channelisation (1991) showed that the drainage works increased mean daily flows by about 5 % and dramatically raised suspended‑sediment concentrations—from 7.8 mg L⁻¹ pre‑channelisation to over 54 mg L⁻¹ afterwards. The altered hydraulics reduced over‑bank storage, increased water‑table draw‑down near the banks and led to habitat loss for spawning salmon and trout. These changes are still evident in reduced redd counts and lower juvenile recruitment observed in recent scientific monitoring.
Angling
The River Main is a noted salmon and sea‑trout fishery. Its clean, oxygen‑rich waters support a late‑season run of Atlantic salmon and a robust population of sea‑trout.
| Species | Season | Typical Run | Notes |
|---|---|---|---|
| Salmon | 17 Mar – 30 Sep | Good late run of salmon and grilse | Access is limited; many stretches are private |
| Sea‑trout | 17 Mar – 12 Oct | Consistent throughout season | Larger sea‑trout often seen in autumn |
Permits & Regulations
Fishing in Northern Ireland is regulated by the Department of Agriculture, Environment and Rural Affairs (DAERA). Anglers must obtain a DAERA rod licence and a River Main permit. Permits can be arranged through the local Inland Fisheries Ireland office in Macroom (Tel (026) 41222) or directly with the River Maine & Brown Flesk Anglers Club (website: http://rivermaineandbrownfleskanglers.webs.com). Guided trips and permit assistance are offered by Tim Landers of Landers Outdoor World (Phone 066 7126644, website http://www.landers.ie).
Scenic Walks & Photography
The river’s course through the Glens offers several informal walking routes. Low‑land tracks reveal limestone cliffs, ancient stone walls and the occasional ruin of old mill buildings. The stretch between Cullybackey and Randalstown is especially photogenic, with gentle pools framed by mature oak and ash trees. While there are no formal visitor centres, the Galgorm Resort – set on the river’s banks – provides wheelchair‑friendly paths, a riverside café and accommodation for those who wish to combine outdoor activity with a comfortable base.

Seasonal Highlights
- Spring (March‑May): Salmon begin their upstream migration; the riverbanks burst into fresh green.
- Summer (June‑August): Peak salmon runs and abundant sea‑trout; ideal for angling and photography.
- Autumn (September‑October): Salmon and sea‑trout runs continue; foliage in the surrounding glens turns golden, providing striking backdrops.
- Winter: Quiet river flow; good for peaceful walks and bird‑watching, though water levels can be lower.
Practical Information
- Access: Free along most of its length, though some sections cross private land – always seek landowner permission.
- Parking: Free roadside pull‑outs are available at several points between Cullybackey and Randalstown.
- Public transport: Regular bus services run to Cullybackey and Randalstown from Belfast; the riverbank is a short walk from the stops.
- Accessibility: Most informal routes are unpaved and uneven; the Galgorm Resort’s riverside paths are wheelchair‑friendly.
