MOTORCYCLE TRAVEL IN Thailand

Completing the Mae Hong Son Loop by motorcycle means stringing together 600 kilometers of mountain curves around Chiang Mai, with a count that has become local folklore: 1,864 curves in total, 762 of which belong to the first stretch alone, between Chiang Mai and Pai.

The number is repeated so often that the Mae Hong Son Chamber of Commerce hands out a certificate to anyone who completes the loop, a tradition that started as a joke among riders and ended up institutionalized.

The route links the backpacker town of Pai, the city of Mae Hong Son with its lake and Burmese-style temples, Khun Yuam, and Mae Sariang, crossing jungle, rice terraces, and Karen and Shan hill-tribe villages hidden in the mist.

It's no accident that the motorcycle-travel world calls it the Holy Grail of Southeast Asia: it's probably the route with the most trip reports, videos, and dedicated guides in the entire region.

Riding Route 1090 by motorcycle between Mae Sot and Umphang means tackling 164 kilometers with a count of 1,219 curves, nearly 7.5 curves per kilometer, winding along a mountain ridge almost without a break.

The Death Highway nickname doesn't come from rider accidents, but from its construction: in the late 1980s the Thai government funded the road through these mountains, and communist insurgents killed around 30 workers during construction, giving the route its grim fame before a single motorcycle ever rode it.

Today the road is fully paved and serves as the gateway to the Umphang Wildlife Sanctuary, home to Thi Lo Su, Thailand's tallest and widest waterfall, dropping 250 meters and spanning nearly 450.

Along with the Mae Hong Son Loop, it's the other route every long-distance rider in Southeast Asia has circled on the map.

Riding the Golden Triangle by motorcycle means visiting the exact point where Thailand, Laos, and Myanmar meet along the Mekong River, a region that for decades was the heart of the world's opium trade before Thailand eradicated the crops in the 1980s and '90s.

The classic route leaves from Chiang Rai, climbs to the Yunnanese hill town of Doi Mae Salong through tea plantations, crosses Doi Tung, where the Thai royal family funded a reforestation project that replaced poppy fields with coffee and flowers, and descends to Mae Sai, the country's northernmost border crossing, before reaching the Golden Triangle viewpoint at Chiang Saen.

Unlike other routes on this list, its fame doesn't rest on riders alone: the name Golden Triangle is recognized worldwide for its history, which is why practically every motorcycle tour operator in northern Thailand includes it in their catalog.

Climbing Doi Inthanon by motorcycle means reaching the highest point in Thailand: 2,565 meters above sea level, on a 106-kilometer ascent from Chiang Mai through Doi Inthanon National Park, established in 1954 as one of the country's first 14 national parks.

The mountain is named after Inthawichayanon, the last great prince of Chiang Mai, who spent his final years protecting these forests and whose remains rest at the summit, the reason the peak's original name was changed.

Near the top stand the twin chedis Naphamethinidon and Naphaphonphumisiri, built in 1987 and 1992 for the king and queen's 60th birthdays, surrounded by gardens that contrast with the rest of the country's tropical landscape.

It's also where Thailand records its lowest temperatures every year, with some winters bringing reports of frost on the ground, something almost unheard of anywhere else in the country.

Route 105 by motorcycle between Mae Sot and Mae Sariang covers 220 kilometers hugging the Myanmar border, closely following the Salween River, with dense jungle on one side and the mountains of Karen State on the other.

One rider described it in a Facebook group of over a thousand members as his favorite road in Thailand, 150 kilometers of pure bliss, and the GT-Rider and Ride Asia forums have had active threads for over a decade tracking the state of the pavement, a sign that this route is closely followed by the long-distance riding community.

Unlike the Mae Hong Son Loop, it carries almost no traffic: it's common to ride entire stretches without passing another vehicle, which makes it the preferred choice for those who've already ridden the better-known routes and want something more solitary.

The stretch of Route 1256 by motorcycle between Pua and Bo Kluea, in Nan province, covers just 47 kilometers, but it climbs along the ridge of Doi Phu Kha National Park with so many tight switchbacks that riders themselves renamed it the Sky Road.

Nan is the least-visited province in northern Thailand despite sharing the same mountainous landscape as Chiang Mai or Mae Hong Son, which leaves this stretch nearly empty even during high season.

Sites specializing in Thailand motorcycle travel describe it outright as the country's best-kept secret, the kind of route ridden by travelers who've already completed the Mae Hong Son Loop and are looking for the same technical demand, minus the organized-tour traffic.

The Doi Ang Khang loop by motorcycle, running from Chiang Mai through Chiang Dao, Fang, and up to the mountain's summit, is described by specialized guides outright as Thailand's steepest climb.

The summit sits at 1,928 meters and hosts Thailand's first royal agricultural station, founded in 1969 by King Bhumibol Adulyadej as part of his program to replace hill-tribe opium crops with cold-climate fruit and flowers, the same project later replicated at Doi Tung.

The mountain is part of the Daen Lao Range, which runs right along the Myanmar border, and the descent toward the villages of Nor Lae and Nong Tao demands careful braking on steep switchbacks that the GT-Rider forums have documented stretch by stretch for over fifteen years.

The Samoeng Loop by motorcycle is every rider's training circuit when they arrive in Chiang Mai: 100 kilometers of gentle curves through forest and mountain villages, completed in a single morning, without the technical demands of other northern routes.

It shows up consistently at number 4 on nearly every list of northern Thailand routes, not because it's spectacular, but because it serves a real purpose: it's where newly arrived riders test their rental bike, the weather, and Thai traffic before committing to something longer like the Mae Hong Son Loop.

The route passes the Queen Sirikit Botanic Garden and Mon Cham, a mountaintop viewpoint with flower gardens that has become a classic backdrop for motorcycle-travel photos on Instagram.

Route 12 by motorcycle between Phitsanulok and Lom Sak, nicknamed the heaven of roads for its smooth pavement and near-nonexistent traffic, crosses Khao Kho, a mountainous region of Phetchabun known as the Thai Alps for its cool climate.

The Khao Kho wind farm crowns the route at around 1,050 meters, with giant turbines that have become one of central Thailand's most photographed viewpoints, alongside strawberry fields that only grow in this area because of the altitude.

Unlike the routes of the deep north, this one connects to the country's central plains, making it the most accessible entry point into Thailand's mountain-road world for riders just starting to explore the country on two wheels.

Reaching Three Pagodas Pass by motorcycle, on the border between Kanchanaburi and Myanmar, means riding one of Southeast Asia's oldest invasion and trade routes: through this same pass, at 282 meters elevation, Burmese armies first invaded the kingdom of Ayutthaya in 1548.

The three pagodas that give the pass its name were only built in 1929, as a symbol of peace between the two countries, but the area was already being crossed by Indian monks in the 3rd century spreading Buddhism into Thailand.

During World War II, Japan routed the infamous Death Railway through here, built with forced labor and Allied prisoners of war, many of whom died during construction. A memorial now stands at the site.

The road from Kanchanaburi passes through Sangkhlaburi, with its wooden bridge over the lake and Wat Wang Wiwekaram temple, before reaching the border checkpoint facing Payathonzu on the Myanmar side.
