The Carlingford Lough Ferry from Greenore leaves on the half hour. Sailing times depend on the day and month so make sure you ask us or go to https://carlingfordferry.com/timetable/. There is even a bike rack on the Ferry ! After a lovely ferry crossing, you will arrive at Greencastle. Take the time to visit the amazing Royal Greencastle Castle just by Greencastle Pier. Ride along the Greencastle Pier Road and at the T junction turn left towards Lisnacree on the Benagh Road. It’s signposted Warrenpoint and Newry. At Lisnacree you turn left on to the A2 to Warrenpoint…The road pretty much follows the contours of the Lough and it will take about 30 minutes to ride to Rostrevor and Kilbroney Park. Plenty of good reasons to stop off here including a cafe at the Mountain Bike trailhead…As an advisory note, MAKE SURE YOU HAVE A CREDIT/DEBIT CARD or STERLING CASH…(I made that mistake last time and so there was no pit stop for 46km until I got to Omeath !) Cycle a little further and you approach Warrenpoint, I stopped at the Ross Monument to just take in the scenery..The Ross Monument was erected on the shoreline of Carlingford Lough in 1826 to the design of William Vitruvius Morrison, this massive granite obelisk commemorates Major General Robert Ross who had been killed in September 1814 while advancing on Baltimore during the American War.
