I don't go there for the trails. I go there to lay on the beach under an umbrella and eat pineapples, mangos, som tam, and bing gai. Throw in a couple of Singha's and I'm good to go. My wife is Lao and has relatives in Kong Chiam so we generally spend two weeks on the beach, a week in Ubon/Kong Chiam, and a week shopping in Bangkok. Beautiful country, wonderful people, good parties, and great food.
