South Dublin is an administrative county covering the southwestern suburbs of Dublin rather than a separate city. Tallaght is its main centre, with Clondalkin, Lucan and Rathfarnham the other principal districts.
The county is suburban rather than a destination, though the round tower at Clondalkin is a fine early medieval survival. The Dublin Mountains rise along its southern edge with walking trails and views over the city, and central Dublin with Trinity College and the Book of Kells is a short journey northeast.
The Luas tram reaches Tallaght and the city centre, supplemented by buses. The county is spread out and a car helps for the mountains.
Late spring through early autumn gives the longest daylight and the best chance of dry weather. Rain is possible in any month and the climate is mild year-round.
