It is easy to orientate in the central part of Pattaya, as soon as you understand the overall grid system of roads.
Along the beach, you have Beach Road; then Second Road and Third Road, followed by Sukhumvit Road. On the other axis of the grid, you find many small roads, and three main roads: North Pattaya Road, Central Pattaya Road, and South Pattaya Road. Beach Road is one-way southwards, while Second Road is one-way northwards. (please note that the map is not to scale).
