Arrive in Bangkok
Suvarnabhumi or Don Mueang airport to your hotel near the old city
- Welcome dinner
- Nuit : Bangkok
- Environ 1 h de route
Fly into Bangkok's Suvarnabhumi Airport (BKK), or Don Mueang (DMK) if you arrive on a regional flight, and a driver meets you in the arrivals hall for the ride into the city, usually 45 minutes to an hour depending on traffic.
Soir
Our hotel is in a walkable area near the old city and the Chao Phraya River, so the first evening needs no taxis. Plan to land by about 4 pm to make the briefing; the exact time comes with your final itinerary. If you arrive earlier, rest, or walk down to the river to watch the express boats and rice barges go by. In the early evening your See Sight Tours guide meets the group and walks you through the nine days: the temple dress code, the cash worth carrying and how the one-night stops work. Then we sit down together to a welcome dinner of Thai dishes at a local restaurant. Keep the night short, because tomorrow starts at the Grand Palace gate when it opens.
Compris
- Pick-up at Suvarnabhumi (BKK) or Don Mueang (DMK) airport
- Welcome briefing with your guide
- Welcome dinner
Temps libre : Free until the evening briefing
Grand Palace at opening, Chinatown at night
The Grand Palace and Wat Pho, then Wat Pariwat and Chinatown
- Petit-déjeuner et repas du soir
- Nuit : Bangkok
- Environ 1 h de route

We walk to the Grand Palace for its 8:30 opening, ahead of most tour coaches, and go first to Wat Phra Kaew, the royal temple of the Emerald Buddha, while its courtyards are still quiet. Your guide reads the Ramakien murals that run around the cloister with you, then we cross to the palace halls. Wat Pho is ten minutes' walk south: its reclining Buddha is 46 m long, with mother-of-pearl inlay on the soles of the feet.
Après-midi
Lunch is your choice near Tha Tien pier, and the hottest hours are free at the hotel. Late in the afternoon we drive about 20 minutes south along the river to Wat Pariwat, a working neighbourhood temple whose ordination hall is crowded with modern stucco figures, among them, famously, a small gilded David Beckham.
Soir
As the light goes we walk into Yaowarat, Bangkok's Chinatown, for a street-food dinner: your guide orders, explains each dish and settles the bill.
Compris
- The Grand Palace and Wat Phra Kaew at opening, with your guide
- Wat Pho and the reclining Buddha
- Wat Pariwat
- Street-food dinner in Chinatown (Yaowarat) with your guide
Activités en option
- A Thai massage at the hotel or near Wat Pho in the free midday
Option plus facile : Skip Wat Pariwat and rest at the hotel until we meet for Chinatown.
Temps libre : Lunch and the hottest hours free
Activité : About 3 hours on foot in the morning, in heat. Shoulders and knees must be covered at the Grand Palace.
Floating market, then the River Kwai
Bangkok to Damnoen Saduak floating market, then Kanchanaburi
- Petit-déjeuner et repas du midi
- Nuit : Kanchanaburi
- Environ 3 h de route

Matin
This is the trip's only 7 am departure: we leave Bangkok then to reach Damnoen Saduak, about 100 km south-west, at around 8:30, before the coach groups that fill its canals from mid-morning. It is a busy, visitor-facing market and we say so; early, from a paddle boat, it is still a lively hour of fruit, noodle boats and narrow waterways. From there it is about an hour and a quarter north-west to Kanchanaburi, where the Khwae Noi and Khwae Yai rivers meet.
Après-midi
After lunch by the river we spend the afternoon on the history that made the town known abroad. The Kanchanaburi War Cemetery holds nearly 7,000 Allied prisoners of war who died building the Thailand–Burma Railway in 1942 and 1943. Beside it, the Thailand–Burma Railway Centre explains how the line was forced through and what it cost, including the far larger toll among conscripted Asian labourers.
Soir
We give the museum time, not a quick pass, and walk onto the bridge at dusk.
Compris
- Damnoen Saduak floating market by paddle boat
- Lunch by the river in Kanchanaburi
- Kanchanaburi War Cemetery with your guide
- Thailand–Burma Railway Centre
- The Bridge over the River Kwai at dusk
Temps libre : Evening free by the river
Activité : Today is the only 7 am departure, chosen to reach the market before the crowds. The other early slots are the optional 7:30 bridge walk on day 4, the 6:30 bike ride into Sukhothai park on day 6 and the 7:30 departure for Chiang Rai on day 9.
The bridge early, Ayutthaya at sunset
Kanchanaburi to Ayutthaya, then a boat around the old island
- Petit-déjeuner et repas du midi
- Nuit : Ayutthaya
- Environ 3 h de route

If you are up for it, walk the bridge with your guide at about 7:30, before the first tour groups, while the river is still and the curved steel spans are in soft light; the straight central spans replaced those bombed in 1945.
Matin
After breakfast we drive about three hours east across the rice plains to Ayutthaya, capital of Siam from 1351 until the Burmese army sacked it in 1767, and a UNESCO World Heritage Site since 1991.
Après-midi
Lunch on arrival is grilled river prawns, the town's speciality, then a rest through the heat. From about 3:30 your guide takes you through the ruins on the old island: Wat Mahathat, where a sandstone Buddha head sits wrapped in the roots of a fig tree, and the three chedis of Wat Phra Si Sanphet.
Soir
As the sun drops we board a long-tail boat for a loop around the island, past riverside temples and the towers of Wat Chai Watthanaram against the evening sky.
Compris
- Early walk on the Bridge over the River Kwai
- Lunch in Ayutthaya
- Wat Mahathat and Wat Phra Si Sanphet with your guide
- Sunset long-tail boat around Ayutthaya island
Option plus facile : Skip the early bridge walk and join the group at breakfast.
Temps libre : Evening free; the night market is a short walk away
Activité : About 2 hours on foot in the ruins, on flat paths and brick steps.
Wat Chai Watthanaram, then the train north
Ayutthaya to Phitsanulok by train, then by road to Old Sukhothai
- Petit-déjeuner et repas du midi
- Nuit : Sukhothai
- Environ 1 h de route

We are at Wat Chai Watthanaram when it opens at 8 am, with the great central prang and its ring of smaller towers almost to ourselves. King Prasat Thong began it in 1630 on the west bank of the Chao Phraya, in a style that looks back to Angkor, and your guide explains how the plan mirrors the Buddhist universe. We give it about an hour, because the train north leaves Ayutthaya station, a short drive away, at about 10 am. Rather than nearly five hours in a van, we take a daytime express train on the Northern Line to Phitsanulok, roughly 320 km in about three to three and a half hours, with rice fields, sugar cane and small station towns going past the window. Our vehicle drives up separately with your luggage.
Après-midi
We arrive at about 1:15 pm and sit down to a late lunch in Phitsanulok, then it is about an hour by road to Old Sukhothai, where we stay a short ride from the gates of the historical park.
Soir
The evening is free: try Sukhothai noodles at a stall near the hotel.
Compris
- Wat Chai Watthanaram at opening, with your guide
- Daytime express train from Ayutthaya to Phitsanulok, about 3 to 3.5 hours
- Lunch in Phitsanulok
- Transfer from Phitsanulok to Old Sukhothai, with your luggage carried in our vehicle
Temps libre : Evening free in Old Sukhothai
Activité : Lunch is late, at about 1:30 pm in Phitsanulok, so buy a snack at Ayutthaya station or keep one from breakfast. Thai trains often run late; lunch moves with the train, and nothing is booked in Sukhothai until the next morning. We confirm the train time when you book.
Sukhothai at sunrise, then north to Chiang Mai
Sukhothai Historical Park by bike, then Wat Phra That Lampang Luang and Chiang Mai
- Petit-déjeuner et repas du midi
- Nuit : Chiang Mai
- Environ 5 h de route
We ride into Sukhothai Historical Park at opening, around 6:30, on flat paths between lotus ponds, and give it about three hours, not the rushed two of a pass-through. Sukhothai was the first capital of a Thai kingdom in the 13th century, and the park is a UNESCO World Heritage Site.
Matin
Your guide leads you to Wat Mahathat as the first light reaches the seated Buddhas among its columns, then Wat Sra Si on its island and, outside the walls, Wat Si Chum, where a seated Buddha about 15 m high fills a roofless hall and looks out through a narrow opening. Breakfast is back at the hotel, then comes the longest road day: about 320 km and close to five hours of driving, the one day over our 4-hour cap.
Après-midi
There is no railway to Sukhothai and a flight would mean going back through Bangkok, so we split the drive with lunch in Lampang and an hour at Wat Phra That Lampang Luang, a walled Lanna temple whose open-sided wooden hall dates from the late 15th century. We reach Chiang Mai in the late afternoon.
Compris
- Sukhothai Historical Park by bike at sunrise with your guide, bike hire included
- Wat Mahathat, Wat Sra Si and Wat Si Chum
- Lunch in Lampang
- Wat Phra That Lampang Luang
Option plus facile : Ride in the vehicle between the temples and walk the short distances inside each one.
Option plus active : Add Wat Saphan Hin in the western zone, a hilltop temple reached by a stone path, with a standing Buddha looking back over the park.
Temps libre : Evening free in Chiang Mai
Activité : About 10 km of flat cycling at an easy pace. The drive, close to five hours with the Lampang Luang detour, is the one day over our 4-hour cap; the Lampang stops break it into two halves.
A day with elephants, no riding
Chiang Mai to an elephant sanctuary in the hills and back
- Petit-déjeuner et repas du midi
- Nuit : Chiang Mai
- Environ 2.5 h de route
About an hour and a quarter from the city, in the forested hills outside Chiang Mai, we spend the day at an elephant sanctuary chosen for how it treats its animals: no riding, no bathing with the elephants, no shows or painting, and elephants free to move away from people. We name it when we confirm your dates. Reviewers of other trips describe watching rescued elephants from a distant platform; here a small group walks out with a keeper and a sanctuary guide, close enough to watch how the herd feeds, plays and talks to each other, at the distance the keepers set. You help prepare their food, hear how each animal came to the sanctuary, and learn what the end of Thailand's logging trade meant for working elephants and the families who kept them.
Après-midi
Lunch is on site. We are back in Chiang Mai by mid-afternoon, and the rest of the day is yours: a massage, a walk inside the old-city moat or, on a Sunday, the Walking Street market from Tha Phae Gate.
Compris
- A day at an elephant sanctuary near Chiang Mai, with sanctuary guides
- Helping prepare the elephants' food
- Lunch at the sanctuary
Activités en option
- A Thai massage in the old city
Option plus facile : Stay at the sanctuary's shaded viewpoint while the group walks out with the keepers.
Temps libre : Late afternoon and evening free
Activité : Easy walking on uneven, sometimes muddy ground for 2 to 3 hours; wear closed shoes and clothes you do not mind getting dirty.
Market, cooking class and Doi Suthep
A Chiang Mai market and cooking school, then Wat Phra That Doi Suthep
- Petit-déjeuner, repas du midi et repas du soir
- Nuit : Chiang Mai
- Environ 1.5 h de route
Matin
The morning starts at a fresh market with your cooking teacher, picking out herbs, chillies, galangal and the pastes you will pound later.
Après-midi
The class, at a school we name when we confirm your dates, covers the north as well as the familiar dishes: khao soi, the curry noodle soup of Chiang Mai, alongside a curry, a stir-fry and a salad, and what you cook is your lunch. The afternoon is free. In the late afternoon we drive about 15 km up the mountain west of the city to Wat Phra That Doi Suthep, at roughly 1,000 m, the most revered temple of the region. A staircase of about 300 steps, its balustrades shaped as naga serpents, climbs to a gilded chedi, and there is a lift for anyone who prefers it. From the terrace Chiang Mai spreads across the valley below as the light goes.
Soir
We come down for a farewell dinner of northern Thai food: sai ua sausage, nam prik ong and sticky rice, eaten with your hands if you like.
Compris
- Market visit with your cooking teacher
- Northern Thai cooking class, with the lunch you cook
- Wat Phra That Doi Suthep in the late afternoon, lift included
- Farewell dinner of northern Thai food
Option plus facile : Take the lift up to the temple terrace instead of the staircase.
Option plus active : Climb the roughly 300 naga steps to the chedi.
Temps libre : Afternoon free
The White Temple and Chiang Rai
Chiang Mai to Wat Rong Khun and Chiang Rai, then Chiang Rai airport
- Petit-déjeuner et repas du midi
- Environ 4 h de route
Matin
We leave Chiang Mai after breakfast, at about 7:30, and drive about three hours north-east through the hills to Chiang Rai, the stop travellers on other northern trips most often ask to add. Wat Rong Khun, the White Temple, is the work of the Chiang Rai artist Chalermchai Kositpipat, who began rebuilding it in 1997 and is still adding to it: a white, mirror-glass temple reached by a bridge over a pit of reaching hands, with murals inside that set Buddhist scenes beside figures from films and the news. Your guide explains the symbolism before we go in.
Après-midi
After lunch in Chiang Rai, and the Blue Temple, Wat Rong Suea Ten, if time allows, we drive to Mae Fah Luang–Chiang Rai International Airport (CEI), arriving about 2:30 pm; with these short legs the day has about four hours on the road in all, and your guide sees you to check-in. Chiang Rai has direct flights to Bangkok to connect home; book one leaving after about 4:30 pm. If you need to fly from Chiang Mai instead, we drop you at Chiang Mai International Airport (CNX) in the morning.
Compris
- Wat Rong Khun (the White Temple) with your guide
- Lunch in Chiang Rai
- Wat Rong Suea Ten (the Blue Temple), time allowing
- Drop-off at Chiang Rai airport (CEI)
Option plus facile : Skip the Chiang Rai day and take a morning drop at Chiang Mai airport (CNX).
Activité : Book a Chiang Rai to Bangkok flight leaving after about 4:30 pm, and allow a long connection in Bangkok for your flight home.

Faune et météo : November to February is the cool, dry season and the best time for this route. March to May is hot, often above 35°C, and the north is often hazy from crop burning between February and April. June to October brings the rains, mostly as afternoon downpours, with green rice fields and fewer visitors.

Questions
Les prix indiqués dans ces réponses s'appliquent à compter du 1er janv. 2027. Offre du Vendredi fou : 15 % de rabais sur le prix en petit groupe pour les demandes reçues au plus tard le 1er déc. 2026. À partir de CAD 2,225 par personne. Du 2 déc. au 31 déc. : à partir de CAD 2,410. À compter du 1er janv. 2027 : à partir de CAD 2,620.
What does the price include?
Eight nights in central hotels, breakfast daily, seven lunches and three dinners, airport transfers at both ends, our own van and driver, the daytime express train north, your See Sight Tours guide throughout, and every visit in the day plan, including the Grand Palace, the floating-market boat, the elephant sanctuary, the cooking class, Doi Suthep and the White Temple.
How big is the group?
The small-group trip runs with 7 to 12 guests, never more. That keeps everyone within earshot of the guide at the Grand Palace, on one boat in Ayutthaya and around one table at lunch, and it lets the group move quickly at early openings.
Who leads the trip?
A See Sight Tours guide travels with the group from the Bangkok airport pick-up to the Chiang Rai drop-off, without a handover partway through. Sanctuary guides and keepers join us with the elephants, and a cooking teacher runs the class in Chiang Mai.
How fit do I need to be for this Thailand tour?
Easy fitness is enough. Expect 2 to 4 hours a day on foot on flat temple grounds in heat, a flat bike ride of about 10 km in Sukhothai, which you can do from the vehicle instead, and about 300 steps at Doi Suthep, with a lift beside them.
I'm travelling solo. Is there a single supplement?
Yes, and it is published up front: a room of your own is CAD 495 on top of the twin-share price, shown before you book rather than at checkout. Solo travellers join the same group, sit at the same tables and get the same guide time as everyone else.
When is the best time to go to northern Thailand?
November to February is the best time: cool, dry and clear. March to May is hot, often above 35°C, and the north can be hazy from crop burning between February and April. June to October is the rainy season, with afternoon downpours, green rice fields and fewer visitors.
How does booking work?
Choose a date and send a request to book. We confirm your place within 24 hours, with the hotels and the final timings, and no payment is taken until we have confirmed. If a date cannot run, we tell you straight away and suggest the nearest one that can.
Can we travel privately or on our own dates?
Yes. Besides the small group, the trip runs as a private trip for your party only, on a date you choose, from CAD 4,720 per person. If you would rather travel independently on your own dates, ask us from the dates section and we will quote the same route without a group.
Do I need a visa for Thailand?
Canadian and US passport holders currently enter Thailand without a visa for a short stay, but the length allowed changed in 2024 and has been under review since, so we confirm the rule when you book. Every visitor also completes the online Thailand Digital Arrival Card before arrival.
Is the elephant sanctuary ethical?
We only use a sanctuary with no riding, no bathing with the elephants and no shows or painting, where the elephants can walk away from people. You walk with the keepers at the distance they set and help prepare food. We name the sanctuary when we confirm your dates.
How long are the drives?
Road days are three to four hours: days 3, 4 and 9. The long hop north from Ayutthaya is a daytime express train of about three to three and a half hours, not a van. Sukhothai to Chiang Mai is the one longer day, close to five hours of driving, split by lunch and a temple in Lampang. Each day's time is on this page.
How is this different from your Bangkok, Chiang Mai and islands trip?
This trip goes overland through the central plains, with Kanchanaburi, a night in Ayutthaya, Sukhothai at sunrise, Lampang and Chiang Rai, in 9 days. The 13-day islands trip flies north, then adds Khao Sok and the Krabi islands, so choose it if you want beaches.
