Cosmopolitan, colourful and over a thousand years old, Dublin presents a fine starting point for visitors to Ireland. This capital city is split in two by the River Liffey, which gives form to the city and has no less than nine bridges spanning it. Easily explored on foot, central Dublin presents a wealth of historic landmarks, from ancient cathedrals to gracious Georgian buildings that pay testimony to days gone by. There are several attractions on both sides of the Liffey, ranging from gaols and castles to the birthplaces of famous poets and writers and guided literary trails.Not far from the city in County Wicklow are the Wicklow Mountains, where hills and glens, forests and waterfalls attract weekend walkers and nature-lovers.
