<h3>How to travel between Thailand, Vietnam, Laos, Cambodia?</h3>

I will be traveling to Thailand soon and, after a few weeks there, I hope to visit Vietnam, Cambodia and Laos. Does anyone know the best way to get around? How reliable are the rail links etc?


<strong>Cambodia best answer:</strong>
<p><i>Answer by noodles</i><br/>Hi,
From Thailand to Laos: You can take a train or bus from Bangkok to Nongkhai(12hrs ride) for $ 20 and up then from Nongkhai you can take a bus to Vientiane, Laos for a few dollars(45mns to 1hr ride).
From Laos to Vietnam and Cambodia: There are tour buses from Vientiane, Laos to Vietname and Cambodia, but I am not sure about the prices. It can't be much though. More info about Laos, you can check out http://www.laos411.com/</p>

Exploring the ruins &amp; temples around Angkor Wat in Cambodia with Jason &amp; Sanna. Best trip ever, despite the dangers &amp; awful travel conditions. Awesome</p>
