Visit Doi Suthep shrine (open ~6:00–17:00); allow time for the 15–20 minute climb or take the short drive; excellent city views and cultural experience.
Have dinner in Nimman (try Khao Kha Moo or fusion Thai) then hit the nearby Saturday Night Market (if it's a Saturday) or Chiang Mai Night Bazaar in the evening.
Minivan ride from Chiang Mai to Pai takes ~3–4 hours on winding mountain roads; private car is faster but more expensive. Depart early to maximize time in Pai.
Explore Pai Canyon (open daylight hours; best before sunset). Trails require careful footing; the ridge offers panoramic views and fun paths for photos.
Head back to a viewpoint (Pai Canyon or local sunset spots) for sunset photos, then have dinner in town — try grilled river fish or pad thai at a local stall.
Speedboat to Pak Bara then minivan to Hat Yai or direct connecting flight to Bangkok depending on pre-booking; allow several hours for connections—book early-evening flight to BKK.
Experience the world-famous Full Moon Party (typically starts around 22:00 and runs until dawn). Stay safe, watch personal belongings, and pre-book return transport.
Afternoon snorkel trip to spots like Shark Bay or Mango Bay, or try an introductory dive (PADI Discover Scuba) — operators open daily, book in advance.
