Bangkok, Chiang Mai & Phuket: Thailand's Classic Triangle

Nine days split evenly across three cities leaves almost no slack later on, which makes today the only genuinely free evening of the whole trip — worth treating as rest rather than a chance to get ahead on sightseeing. Khaosan and Silom offer very different first nights; neither is wrong, but they set different tones for the week.

Watch out: This is the only unscheduled evening in the whole nine days — the temple circuit starts tomorrow and the pace doesn't really let up after that.

• Arrive and check in
• Khaosan Road or Silom evening

With Chinatown's food walk added onto the end of the usual temple circuit, this day needs to move briskly through the Grand Palace and Wat Pho to leave real energy for Yaowarat after dark — trying to linger at both ends isn't realistic. The river express boat is the efficient link between the temples and doubles as a break from walking.

• Grand Palace, Wat Pho, Wat Arun
• Chao Phraya river express boat
• Chinatown evening food walk

Only three days in Bangkok on this trip means Chatuchak has to fall on a weekend to make the cut at all — check the calendar before counting on it. Jim Thompson House in the middle of the day is the one indoor, unhurried stop between two much busier ones.

Watch out: With only three Bangkok days on this route, there's no spare day to shift Chatuchak to if it doesn't land on a weekend.

• Chatuchak Weekend Market (Sat/Sun)
• Jim Thompson House
• Rooftop bar evening

This is the pivot of the whole trip, swapping Bangkok's scale for Chiang Mai's smaller old city, and it's worth keeping deliberately light — a moat walk and a café stop in Nimman, nothing that demands much after a flight and three intense Bangkok days behind it.

• Morning flight north
• Old City moat walk
• Nimman café district

Going early for Doi Suthep matters more on this trip than most, because tomorrow's sanctuary-and-cooking-class day is already the busiest on the itinerary — front-loading the temple mountain here protects some energy for that. The Night Market's two-day window means there's no real risk of missing it.

• Doi Suthep sunrise or morning
• Wat Chedi Luang Old City
• Saturday or Sunday Night Market

This is the last full day in Chiang Mai before flying south, and it's also the most physically demanding of the three-city trip — sanctuary in the morning, cooking class in the afternoon, and the Night Bazaar only if there's anything left by evening. It's fair to treat the market as optional rather than part of the plan.

• Ethical elephant sanctuary half-day
• Thai cooking class afternoon
• Night Bazaar

The last leg of the triangle drops straight from Chiang Mai's cooler mountain mornings into Phuket's beach heat, and after yesterday's sanctuary and cooking class this day is intentionally undemanding — a flight, a swim, and a choice between Bangla Road's noise and a quieter beach bar.

• Morning flight south
• Kata or Karon beach
• Bangla Road or beach bar evening

The choice between Phi Phi and Phang Nga Bay is the actual decision of the day — Phi Phi means more open water and Maya Bay's crowds, Phang Nga means calmer karst scenery and mangroves, and picking one rather than trying both is what keeps this day sane. The Big Buddha viewpoint afterward is a short stop, not a second tour.

Watch out: Phi Phi and Phang Nga Bay tours both run as full-day trips, so trying to combine both in one day isn't realistic — pick one.

• Phi Phi speedboat day trip OR Phang Nga Bay tour
• Big Buddha viewpoint
• Rawai seafood

The final morning offers a genuine choice between one last swim and a walk through Phuket Old Town's shophouse streets — after a trip that rarely paused, either is a reasonable way to close it out before the transfer to HKT.

• Morning beach or Phuket Old Town walk
• Depart HKT airport
