The Pattaya Bay area is one of Asia's largest beach resorts and the second most visited city in Thailand, after Bangkok. This panorama overlooks Bali Hai pier and the core of the city. The main sweep of the bay area is divided into two principal beachfronts. Pattaya Beach is parallel to the city centre, and runs from Pattaya Nuea south to Walking Street. Along Beach Road are restaurants, shopping areas, and bars. Pratumnak from Wat Phra Yai Pratumnak is on the south side of Pattaya and is popular for its viewpoints and the temple (Wat Phra Yai) on top of the hill. Pattaya Park and Pattaya tower are at the south end of Pratumnak and the Pattaya Exhibition And Convention Hall (P.E.A.C.H), is positioned at the north end of Pratumnak. In recent years, Pratumnak has gained in popularity because of its more natural environment, nicer beaches, and its convenient location between Jomtien and Pattaya city. Jomtien is divided from Pattaya by Thepprasit Road, the southern route into Pattaya city. It consists of high-rise condominiums, beach side hotels, bungalow complexes, shops, bars, and restaurants. Offshore islands include three "near islands": Ko Lan (main island), Ko Sak, and Ko Krok, 7 kilometres (4.3 mi) from the shore of Pattaya. The "far islands" are Ko Phai (main island), Ko Man Wichai, Ko Hu Chang and Ko Klung Badan, located offshore further west of the "near islands". Ko Rin lies offshore to the south-west, south of Ko Phai group. The names "near islands", "far islands", and "Coral Island" are used for marketing purposes only and do not correspond to any naming conventions of the island groups and are not shown on maritime charts published by the Hydrographic Service of the Royal Thai Navy. In June 2016 the Regional Environmental Office reported that, "The sea water along the busy central Pattaya beaches is of poor quality and could endanger human and marine life.
