The capital, Bangkok, is ideal for entertainment and shopping, tempered with picturesque temples and sky-high views. Venture to the islands in the Gulf of Thailand or Andaman Sea, such as Koh Samui or Phuket, for postcard-perfect beaches fringed with palm trees and ringed with clear, inviting water to be in the lap of affordable luxury. Or head north to Chiang Mai, a mountain town full of culture, tradition and spa rituals to indulge in.
