Driving around Limerick can be a little confusing because of the profusion of one-way streets -- it's best to park your car and walk to see the sights. However, you might want to drive to King's Island for King John's Castle (there's a free parking lot opposite the castle). If you need to park downtown, head for the lot at Arthur's Quay, which is convenient for sightseeing and shopping, and well signposted. Parking in the city costs around €1.50 per hour.
If you need to rent a car in Limerick city, contact Irish Car Rental (Ennis Road, Limerick; tel. 1850/206088 or 061/206025; www.irishcarrentals.com). Most major international car-rental firms maintain desks at Shannon Airport.
On foot, the city's streets are fairly easy to figure out, and the main central street has a changing name -- it's Rutland Street in the north and O'Connell Street and Quinlan Street in the south. Most tourist sights are in the north on King's Island, which is the oldest part of the city, although some are to the south around Pery Square (where the architecture is grand Georgian buildings) and on the river's edge. A good way to hit the high points is to pick up a booklet outlining the Tourist Trail at the tourist office and in bookshops.
