Do you need to check opening hours before visiting Narrow Water Castle?
Yes. Narrow Water Castle, also called Narrow Water Keep, stands on Newry Road near Warrenpoint, BT34 2FJ, and is not listed as continuously open to visitors.
The Department for Communities says entry is during specified opening hours and advises checking current arrangements and any charges. The 16th-century tower and bawn guard a narrow section of Carlingford Lough. The site is separate from ordinary roadside viewing areas and may have controlled access to the structure.
Practical advice: Confirm opening before making a dedicated journey, and check for suitable signed parking. Do not stop on the main road or enter restricted masonry areas simply because the exterior can be seen.
