Remnants of old charcoal kilns found at Siam Village in Kubang Badak are about 100 years old, from approximately the same time as World War I. However, little research has been conducted into promoting the antiquity of remnant charcoal kilns as a representation of the historical inheritance of the Siamese community and their early settlement on Langkawi Island. This paper reveals the great potential of the abandoned charcoal kilns as a tourist site and shows the role of heritage conservation through reviewing the conditions. Following the methodology, firstly, charcoal kilns in Malaysia are investigated in term of their natural, cultural, and social history. Secondly, interviews were conducted to examine empirically the community life of that heritage area and the impacts of the charcoal kiln as tourist product. The segmentation of the narration into preservation means, sustainable activities, and historical knowledge is exemplified by extracting important data for taxonomic derivation of heritage conservation, economic, and community development. Finally, a set of guidelines including conservation approaches is proposed to support sustainable tourism development. The findings from the interviews conclude that the conservation of remnant charcoal kilns is vital for the long-term sustainability of cultural heritage tourism.
