Make sure you have enough gas in the tank, because Londonderry is well worth a detour. Situated 18 miles from Cranagh, it offers up some fantastic attractions, such as Derry City Walls and Museum of Free Derry and Bloody Sunday Memorial. Belfast, 50 miles away, is another destination that’s worth the trek. Swing by Titanic Belfast and Belfast Castle, two top-notch sights in the area.
