Isan, the area of Northeast Thailand, makes up one third of the country. Bordered by Laos and the Mekong river, it is home to some of the most scenic yet untouched areas in Thailand. Far from the tourist trail, it.s the part of Thailand where you can truly experience what daily life is like in the country. Our home town of Nong Khai, Isan, is on the shores of the legendary Mekong River. Vientiane, the capital of Laos, is just a 30-minute drive away via the Friendship Bridge linking Thailand and Laos.
