Six Mile Water River
The Six Mile Water flows through Antrim before joining Lough Neagh. Its wooded banks, historic gardens, and fishing stretches make it an accessible nature escape from Belfast.
The Six Mile Water is a river in Northern Ireland that flows through County Antrim before emptying into Lough Neagh, Ireland's largest lake. It winds past the town of Antrim for several kilometres, offering a natural corridor prized for walking, fishing, and wildlife watching. Its name derives from the approximate distance between its source and mouth.
What to See
Along the river, wooded banks shelter grey herons, kingfishers, and otters. Antrim Castle Gardens border the river and feature restored historic gardens. Further downstream, the river widens as it approaches Lough Neagh, where landscapes open onto vast water vistas.
History and Context
The Six Mile Water played an important economic role in the region: its waters once powered linen mills, a central industry to Ulster in the 18th and 19th centuries. Remnants of some of these mills remain visible along the waterway. The river also marks the historic boundary of several lordly estates throughout County Antrim.
Highlights of Your Visit
Antrim Castle Gardens
These restored 17th-century Franco-Dutch gardens run directly alongside the river. Their geometric canals and clipped tree-lined avenues form a rare ensemble in Northern Ireland.
Riverside Trails
Marked pathways allow you to follow the river upstream from Antrim town centre. Dense riparian vegetation creates a peaceful atmosphere, contrasting sharply with the nearby town.
Brown Trout Fishing
The Six Mile Water is renowned for brown trout fishing. Local angling associations manage fishing rights across different stretches.
Photography Tips
Early morning raking light across the Antrim Castle Gardens' canals produces sharp reflections. In autumn, the russet foliage of the banks offers intense colour. The stretch near the mouth, more open in character, suits landscape photography with Lough Neagh as a backdrop.
Location and Access
The river flows through Antrim town, approximately 30 km northwest of Belfast. The most convenient access point is the Antrim Castle Gardens car park in town centre. Regular buses connect Belfast to Antrim. Antrim railway station lies within a few minutes' walk of the riverbanks. Main trails are wheelchair-accessible on the sections developed near the gardens.
