Land in Bangkok (Suvarnabhumi). Private transfer to your riverside or central hotel gives a comfortable start after the long haul — recommended: Mandarin Oriental or The Peninsula for honeymoon service and riverside views.
Lunch at Sala Rattanakosin or the hotel riverside restaurant — relaxed Thai and international dishes with views of Wat Arun across the Chao Phraya River.
Take a romantic Chao Phraya dinner cruise (typical times 19:00–21:30) or a quiet riverside table at The Deck; excellent for honeymoon ambience and city night views.
Visit the Grand Palace and Emerald Buddha (open 8:30–15:30). It’s Thailand’s iconic cultural site — arrive early to avoid crowds and dress respectfully (shoulders/knees covered).
Check into a romantic Chiang Mai hotel — recommended: Four Seasons Resort Chiang Mai, Anantara Chiang Mai or boutique 137 Pillars House — then brunch at Rustic & Blue or hotel restaurant.
Visit Wat Chedi Luang and nearby ancient temples (open early morning to late afternoon). The Old City’s tranquil lanes are ideal for relaxed discovery.
Visit Chiang Mai Night Bazaar or the Sunday Walking Street (if your schedule aligns) for souvenirs and lively street food (markets open from ~17:00–23:00).
Spend a half-day at a reputable elephant sanctuary (no riding) where you observe, feed and bathe elephants — most sanctuaries run 8:00–13:00 programmes; book in advance.
Join an evening cooking class (typical times 16:00–20:00) where you shop for ingredients and cook a multi-course meal — a fun, hands-on honeymoon activity.
Couples can try an introductory rock-climbing session (Railay is world-famous) or book a spa treatment at your resort; climbing companies operate morning–afternoon.
Join a speedboat tour to Phi Phi (depart 7:30–8:30, return mid-late afternoon). Highlights: Maya Bay (if open), snorkeling at spots like Bamboo Island and Pileh Lagoon.
Book a sea-kayaking day tour (depart 08:00) to explore limestone karsts, sea caves and Koh Panyee fishing village; many tours include lunch and run until mid-afternoon.
Hire a professional photographer for a 1–2 hour honeymoon shoot at iconic locations (Grand Palace approach or riverside) — a lasting memory of the trip.
Spend the morning at Siam Paragon, CentralWorld or MBK for last-minute souvenirs, clothing and gifts; malls typically open 10:00–22:00 (MBK opens earlier).
