Soon to be established as a national maritime museum, the Underwater Archaeological Office is located within Khai Noen Wong specialising in exhibits on Thailand's merchant marine and items discovered from underwater archaeological explorations from all over the country. There are also exhibits of ancient sailing routes and products. An exhibition chamber deals with the history and culture of the people of Chanthaburi.
Using the Tha Mai-Bang Kachai route cars can easily access the Khao Laem Sing Forest Park ,some 25 kilometres from Tha Mai. The route passes through Wat Khao Laem Sing right up to the park headquarters on a hill. Alternatively, visitors can charter a boat from Laem Sing beach to Ao Krathing Beach ,just 400 metres away, and walk up to the park. Camping is allowed on application.
Khao Laem Sing is a small hill 172 metres above the sea. Located to the east of the mouth of the Chanthaburi River, it has a cape jutting into the sea which looks like a sprawling lion. There is an old fortification called Pom Phairi Phinat built during the reign of King Rama III.
