Wat Yai Chom Prasat Located on Highway No.35 with a left turn after crossing the Tha Chin River, this is an ancient temple presumed to have been built during the Ayutthaya era. The doors and windows of both the old and new chapels were neatly and beautifully carved in various floral designs. It is believed the craftsmen were Chinese, as the carvings include some Chinese trees.
Mahachai Market This is one of Thailand's largest traditional fresh seafood markets, but visitors can find much more than seafood, especially if there is time to spare. Handicrafts such as wicker furniture, pottery and local sarongs are among the colourful offerings in the market. Crossing the river from Mahachai to the west bank, visitors will arrive at Tha Chalom, a large fishing village and industrial land for marine products.
Wat Chong Lom or Wat Sutthi Wata Wararam This temple fronting the river mouth is located at Tambon Tha Chalom on the western side of the Tha Chin River. It was constructed during the Ayutthaya period. Religious buildings in the temple have been beautifully renovated. The windy area by the sea is used as a rest area for the locals.
Wichian Chodok Fortress This fortress is located near the city pillar shrine in the town. It was constructed in 1827 during the reign of King Rama III to prevent sea invasion by an enemy. It can be seen as ruins nowadays. The cannons, which used to be housed in the fortress, are now displayed at the city pillar shrine and the city hall.
Phanthai Norasing Shrine This is regarded as the symbol of honesty. It was erected to be a memorial to Phanthai Norasing, a man of integrity of the Ayutthaya period. The historic event occurred in 1704 when Phra Chao Sua, a king of Ayutthaya, made a royal visit by the Ekkachai royal barge via the curved Khok Kham Canal. Phanthai Norasing, who was the coxswain, could not operate the steering, thus causing the prow to be broken by hitting the limb of a tree. To foster the palace law, the coxswain then begged the king to slaughter him although he was forgiven. After his death, the king built a shrine in Khlong Khok Kham and commanded to have a new canal, later named Khlong Mahachai, dug to eliminate the sharp curves of Khok Kham Canal. A cruise along the canal via mangrove forests and fishery villages is organised by Khun Narin Bunruam Tel: 0-3441-2490.
Ao Mahachai Mangrove Forest Study Centre offers a nature trail along a mangrove forest around the Tha Chin Estuary. From the town, take Sutthiwawithi Road for 2.5 kilometres, then turn left and proceed for 6.5 kilometres to the centre.
