Khmer ruins, Mekong sunsets and Thailand's boldest food

Northeastern Thailand (Isan)

Isan is the country's largest and least touristed region — Khmer temple ruins, silk villages and the mighty Mekong.

Why visit Isan

Isan rewards travellers who like their trips unfiltered: sandstone Khmer sanctuaries, riverside towns, village markets and the spiciest, most flavourful food in Thailand.

Highlights

  • Phanom Rung and Phimai Khmer sanctuaries
  • Nong Khai and the Mekong river road
  • Khao Yai National Park and its vineyards
  • Rocket festivals, silk weaving and som tam

When to go

November to February is cool and dry. The green season from June brings lush landscapes and lively festivals.
