Trip to Vietnam, Cambodia and Laos

Hi there,

I plan to go to Siem Reap for some volunteer work and want to see a bit of Vietnam and Laos as well before/after that. My idea is to fly to Ho Chi Minh City and then travel to Siem Reap from there. My flight back to Europe should then be from Hanoi, so that I'm able to see a bit more from Vietnam and Laos as well. Timeframe to be defined, would suppose approx. 1 week to travel to Siem Reap and approx. 1 week to go from Siem Reap to Hanoi.

Do you have any tipps / recommendations on where to go and how to go there?

Thanks and best regards,
Nina
