Grand South East Asia Loop Adventure

Bangkok → Siem Reap 38 days Up to 20

About this trip

This 38-day trip takes you overland through Thailand, Laos, Vietnam and Cambodia, starting in Bangkok and finishing in Siem Reap. It's a long haul across four countries, so expect a lot of movement and a wide range of scenery along the way.

You'll take in city markets, colonial-era towns, countryside, and coastline, moving from Thailand's cities through Laos and Vietnam before ending among Cambodia's temples and beaches.

It's a fully guided group trip with a moderate pace, giving you a broad introduction to the region rather than a deep dive into any one place.

What you'll do

  • Explore Bangkok's markets and city life
  • Take in the colonial history and landscapes of Laos
  • Travel through Vietnam's cities and countryside
  • See Cambodia's beaches and ancient temples
  • Finish the journey at the temples of Siem Reap
Good to know
  • Covers four countries in 38 days, so it suits travellers who want breadth over slow travel
  • Choice of private or shared rooms depending on preference
  • Moderate pace with a fully guided group throughout
