At 35 kilometres from the centre of Rayong , Mount Fa Chi is located, from the top of which there are picturesque views of the Kraburi River with islands and neighbouring Myanmar. During World War II, Japanese soldiers used the area as their port, and even a sunken cargo ship remained here, which can now only be seen at low tide. The observation deck, where a narrow one-lane road leads, is 259 meters above sea level.
In the morning before dawn, the river valley is covered with fog so that a thick veil can be seen from the top of Mount Fa Chi. The sunsets from the observation deck are especially beautiful.
