The Golden Triangle, Chiang Saen, and Mae Sai sit in the far northeastern corner of Chiang Rai, lined up along the Mekong and the border, so you can drive them as one easy loop. From Chiang Rai city to Chiang Saen is about 60 km and roughly 1 hour. The Golden Triangle is a little further up from Chiang Saen, then it's another 37 km or so to Mae Sai (taking Highway 1290 along the river), about 40 minutes.
We'd suggest renting your own vehicle, since the sights are spread out and public transport isn't convenient. A car rents for around 900–1,200 THB a day, or a motorbike for 250–350 THB a day. If you'd rather not drive, you can hire a car with a driver for the day for around 1,800–2,500 THB. This plan runs as 2 days and 1 night with an overnight stay on the Mekong in Chiang Saen, but if you're short on time you can squeeze it into a single day by cutting a few stops.
Day 1
North to Chiang Saen, then a Mekong cruise at the Golden Triangle
08:00
Leave Chiang Rai city for Chiang SaenTake Highway 1016, about 1 hour on flat, easy roads. Grab khao soi or nam ngiao in town before you go if you like — 40–60 THB a bowl.
09:00
Ancient town of Chiang Saen + Wat Chedi LuangAn old town more than 700 years old, built in the Lanna era. Wat Chedi Luang has the largest Lanna bell-shaped chedi in Chiang Saen, around 88 meters tall. Walking the old city walls and temple ruins is free.
10:30
Chiang Saen National MuseumRight next to Wat Chedi Luang, with Buddha images and antiquities of the Chiang Saen craft school. Open Wed–Sun, about 9:00–16:00 (closed Mon–Tue). Entry around 30 THB for Thais, 100 THB for foreigners.
12:00
Riverside lunch in Chiang SaenRestaurants along the Mekong in Chiang Saen serve river fish — fried Mekong fish, tom yum — where you can sit and catch the cool breeze. Around 80–200 THB per person.
13:30
Golden Triangle viewpointAbout 15 minutes north of Chiang Saen, this is the point where the Ruak River meets the Mekong, with Laos and Myanmar in view at the same time. There's a large riverside Buddha and a Golden Triangle archway for photos. Free.
14:30
Mekong River cruiseLongtail boats from the Golden Triangle pier run you along the Laos and Myanmar banks. Boat fares are negotiable, around 400–600 THB per boat (seats several people). Some operators stop at Don Sao island on the Laos side. Confirm the price and timing clearly before you get on.
16:00
Hall of Opium, Golden Triangle ParkA well-presented museum on the region's opium history. Open Tue–Sun, about 8:30–16:00 (closed Mon). 150 THB for Thais, 200 THB for foreigners. The last entry is fairly early, so come before 15:30 if you want to go in.
18:00
Check in by the Mekong + dinnerStay the night in Chiang Saen or on the Mekong near the Golden Triangle. Riverside resorts run around 1,000–3,000 THB a night. Have dinner watching the sunset over the Laos side.
Day 1 tips
The Hall of Opium is closed Mondays and shuts at 4 pm. If your trip falls on a Monday, swap in the boat cruise and a walk around the ancient town of Chiang Saen instead, and save the Hall of Opium for next time. For the boat, go in the late afternoon — the light is softer and the photos come out better than at midday.
Day 2
Along the Mekong to Mae Sai, Thailand's northern tip
08:30
Leave Chiang Saen for Mae SaiTake Highway 1290 along the Mekong and the border, about 37 km and roughly 40 minutes. It's a scenic route past riverside villages.
09:30
Wat Phra That Doi Wao + skywalkA temple on a hill in the middle of Mae Sai, with Thailand's northernmost skywalk running about 150 meters. You get a clear view of Tachileik on the Myanmar side. The skywalk costs 50 THB; the temple is open about 7:00–18:00.
11:00
Mae Sai border checkpoint + Thailand's northernmost pointThe northernmost kilometer marker and the bridge over the Sai River to Tachileik are a popular photo spot. Crossing to the Myanmar side opens and closes unpredictably depending on the border situation, so if you're set on crossing, check the checkpoint's status day by day before you go.
12:00
Mae Sai border marketThe market by the checkpoint sells all kinds of food and goods at low prices — good for soaking up the cross-border trade atmosphere. There are souvenirs both Thai and brought across the border. Watch for counterfeits and know how to haggle.
13:00
Lunch in Mae Sai townMae Sai has noodle shops, khao soi, and the usual rice-and-curry spots, plus Tai Yai (Shan) restaurants you can find near the border. Around 50–120 THB a meal.
14:30
Stop by Tham Luang–Khun Nam Nang Non (if you have time)Between Mae Sai and the town center, this is the forest park known worldwide from the Wild Boars cave rescue. You can walk to the cave mouth and the emerald pool. Free.
16:00
Head back to Chiang RaiFrom Mae Sai back to Chiang Rai city, take Highway 1 (Phahonyothin), about 63 km and roughly 1 hour. If you're flying out, allow at least 1.5 hours to reach Mae Fah Luang Airport before your flight.
What to know about crossing the border
The Mae Sai–Tachileik checkpoint was closed for a long stretch during COVID and has opened and closed on and off depending on the situation on the Myanmar side. Sometimes it's open for day trips, sometimes it's shut. If you're set on crossing to Tachileik, don't lock in your plans — call the checkpoint or check the latest news before you set out. Everything on the Thai side in this plan can be visited as normal.

Day tripSqueeze it into one day
Leave Chiang Rai early, do the Golden Triangle, the boat cruise, and the ancient town of Chiang Saen, then push up to Mae Sai in the afternoon and head back to the city by evening. Good if you're short on time.
Add Doi TungAdd Doi Tung & tea plantations
On the way back from Mae Sai, stop at Doi Tung and the Mae Fah Luang Garden along the route, or the Choui Fong tea plantation in Mae Chan, and carry the trip up into the hills.
Slow travelTwo nights on the Mekong
If you love the riverside mood, add another night in Chiang Saen — wake up to the morning mist over the Mekong, cycle around the ancient town, and take it slow.
