Start in Thailand's vibrant capital. Visit Wat Pho temple before 8:30 AM to avoid crowds, then move on to the Grand Palace. A previous traveler shares: "Getting up early for temple visits was worth it - the morning light made the golden stupas absolutely magical." End your days exploring Khao San Road's food scene. Try authentic pad thai from street vendors and if you're feeling adventurous a deep-fried scorpion.

Bangkok & Central Thailand
Get to the Royal Palace compound by 8:30 AM to beat the tour groups. The palace complex gets hot quickly so pack water and wear light clothing.

The candlelit evenings were magical but bring bug spray!"

Northern Thailand
Take an overnight train to Chiang Mai and continue on to relaxed Pai. The mountain road takes 3-4 hours so consider motion sickness pills.

A visitor shared: "Watching the elephants roam freely at the nature park was humbling. Much better than the riding camps elsewhere."
- Days 8-10
