I arrived back in Bangkok yesterday morning. I took a tuk-tuk to the border and then a bus to Bangkok. Thailand and Laos are separated by the Mekong River. The Thai–Lao Friendship Bridge connects the border points. The bridge was built by Australian companies and funded by the Australian government.
The whole trip took over ten hours including the border crossing and a short stop for dinner. Fortunately, the bus was very comfortable, compared with the rattlers I have been used to in Laos and Vietnam. Coming back to Bangkok, completes a full circle through Cambodia, Vietnam and Laos.
any update? where is your next place??
