One of the famous area in Sri Sawat is the reservoir behind the Sri Nakarin Dam. The beginning of this water way is called Lumnam Jone which is the beginning of the ever famous River Kwai. Lumnam Jone can be reach by one tour operator to limit the number of visitor. They can be contacted at Truly Yours tour [http://www.trulyyourstour.com/adventure.asp www.trulyyourstour.com]. The trip is 2 days and 1 night on first weekend of the month. This is the only tour concession to Lumnam Jone.
Amphoe Sri Sawat has two main ethic groups, Thais and Karen. There are several villages of mostly Karen people in tambon Naasuan. Other ethnic groups: near the Amphoe is a small Mon village. Beyong Ong Sit village and off a side road is a Lao village called Jerot. (the villages originally came to help clear the forest when the dam was built and ended up settling in the area). Although many of the Karen ladies do wonderful weaving, (sarongs, blouses, bags) there is no shop locally that sells this. Occasionally there will be a house that will have items for sale - but will be hard to find.
The Mon Bridge and Mon Market (at Sangkhlaburi, about 4 hours away) is a good place to shop.
The Sri Nakharin dam has a nice cafe serving mostly Thai food and snacks and is open every day.
At the Erawan market there are numerous small eating places serving mostly Thai food - but at very reasonable prices.
