Ban Satha Asoke village is found off of the main Ubon-Phibun Mangsahan road. Look for the turn-off to the left at around km5.
The community itself is a self-sufficient vegetarian Buddhist commune. They grow all their own food organically, produce their own environmentally friendly soaps and shampoos, and one of the few breakaway Buddhist sects in Thailand to ordain women.
A day-trip here is a learning experience and it is wonderful to see how people can live so simply in this day and age.
You can read more about the community and how to stay there here:
Have a meal at one of the raft restaurants. You get there by crossing the river bridge towards the side where you get the train. Then, walk down the steps so you are on the river edge. turn left and keep walking on the road till you start seeing restaurants. good food, really relaxed and cool environment. Great way to spend an afternoon or evening.
If you would like to relax in a beautiful shady park, stop at Sirindhorn Dam. With today's increased infrastructure security, you must stop at the guard gate and get a pass, but it is easy to do and free. The dam forms a small reservoir and electricity is generated there. The gardens are well kept. There are park benches and gazebos. A nice looking resort sits on the shore but we did not have time to go there. You may also hire boat rides.
