This land, Tung Prong Thong, used to be an agricultural and fishing land for people who were living in the villages of Sam Pho, Pak Nam, and Pra Sae. The land was recovered by Subdistrict Municipality of Pak Nam Kra Sae and villagers.The collaboration brought back balance to the largest mangrove forest in Rayong Province. The collaboration also led to the development of ecotourism and natural trails. By doing so, it has raised visitors’ awareness to realize the significance of the abundance of forestry in the coasts. Walking along the wooden bridge for 2 kms, the visitors can experience the abundance of mangrove forest with a variety kinds of plants (e.g., samae, black taboon, Lamphun, mangrove, and Prongdang). Tung Prong Thong is the highlight because it happens from yellow Prong trees rubbing. When the sun shines, the scenery is spectacular because it shows golden Prong trees among the green of mangrove trees.
