Nepal has a small road network and an enormous amount of vertical relief to run it through, which is why so much of it is interesting on a motorcycle and why so little of it is quick. The country's best riding falls into three groups: the Kathmandu–Pokhara corridor and the hill roads that hang off it, the high desert road up the Kali Gandaki into Mustang, and the older mountain highways built in the 1950s and 60s that most traffic has since abandoned in favour of faster routes. Everything is affected by the monsoon, roughly June to September, and by an ongoing programme of road upgrades. This overview covers which roads are worth the trip, what condition they are in, and the licence, rental and traffic rules, verified August 2026.
How Nepal's road network is shaped
Almost everything hangs off two axes. The Mahendra Highway, also called the East–West Highway, runs more than 1,030 km (640 miles) across the flat Terai from Mechinagar on the Indian border in the east to Bhim Datta in the far west, crossing over 500 bridges. It is the country's logistical spine and, for a rider, the least interesting road in Nepal — hot, straight and busy. Everything worth riding runs north from it into the hills.
The second axis is the Kathmandu–Pokhara corridor, where most visitors start. From Pokhara the network fans out north toward the Annapurna and Mustang valleys and south back to the Terai on two very different roads. Nepal drives on the left, and the practical rule everywhere is that the largest vehicle takes priority regardless of what the law says.
Top roads in Nepal
| Road | Distance | Character | Start and finish |
|---|---|---|---|
| Prithvi Highway (NH17) | 174 km (108 miles); about 206 km (128 miles) door to door from Kathmandu | River-valley freight corridor, heavy traffic, partly rebuilt to four and six lanes, landslide-prone | Naubise to Prithvi Chowk, Pokhara |
| Kali Gandaki corridor to Upper Mustang | Pokhara to Lo Manthang via Beni, Jomsom and Kagbeni | High trans-Himalayan desert, gravel and riverbed, restricted area with permits and a compulsory guide | Pokhara to Lo Manthang and Kora La at 4,660 m (15,300 ft) |
| Tribhuvan Highway (NH41) | 107 km (66 miles) Naubise to Hetauda, for 32 km (20 miles) as the crow flies | Nepal's oldest highway, 1956, an unbroken series of climbs and descents over the Sivalik Hills | Naubise, west of Kathmandu, to Hetauda and on to Birgunj |
| Siddhartha Highway (NH47) | 181 km (112 miles) | Tight, narrow curves through Palpa hill country; rockfall on the Butwal–Tansen section | Siddharthanagar on the Indian border to Pokhara |
| Araniko Highway (NH34) | 112 km (70 miles) | Kathmandu's road to Tibet; steep-sided and among the most landslide-prone highways in Nepal | Kathmandu to Kodari on the Chinese border |
| Mahendra Highway (NH01) | Over 1,030 km (640 miles) | Flat Terai transit route across the whole country, mostly single-lane each way | Mechinagar in the east to Bhim Datta in the west |
Open the Kathmandu to Pokhara loop via Daman in Google Maps — down the old Tribhuvan Highway over Daman, west along the Terai, then back up the Trishuli, which turns the standard transfer into a proper two or three day circuit.
The Prithvi Highway, the road everyone rides
The Prithvi Highway is the default Kathmandu to Pokhara route and the busiest interesting road in the country. It runs 174 km (108 miles) from Naubise to Pokhara, was built with Chinese assistance between 1967 and 1974, and follows the Trishuli and then the Marsyangdi and Seti valleys through five districts. It carries almost all of the heavy freight into the Kathmandu valley, which is the source of both its traffic and its accident record.
It is also a construction site. The Mugling–Pokhara upgrade, contracted in 2021, was around 60 per cent complete by late 2025, with roughly 30 km already rebuilt to four lanes and six-lane sections planned at Setipul and Lower Gagangauda in Pokhara and at Dulegauda and Khairenitar. Some stretches are now genuinely good, others are single-lane working sites, and bridge operations close sections outright for a few hours at a time on published schedules. Our full Kathmandu to Pokhara guide covers the corridor, the detours to Bandipur and Gorkha, and what to check before you set off.
Upper Mustang, the ride behind the permit
North of Pokhara the Kali Gandaki cuts between Dhaulagiri at 8,167 m (26,795 ft) and Annapurna I at 8,091 m (26,545 ft) to form what is by several measures the deepest gorge in the world; the riverbed below Tukuche sits 5,571 m (18,278 ft) beneath the summit above it. Follow it north past Jomsom and Kagbeni and you cross into the old Kingdom of Lo, a trans-Himalayan desert that receives only 250–400 mm (9.8–15.7 inches) of precipitation a year because the big peaks take the monsoon out of the air first.
Two things make it different from anything else in Nepal. The first is the paperwork: Upper Mustang is a restricted area, every foreign visitor needs a permit issued through a registered Nepali agency and carrying a per-person, per-day fee, and a licensed guide is compulsory and checked. The second is that the rain shadow makes it rideable during the monsoon months when the rest of the country is closing. Our Upper Mustang guide covers the permits, the road surface and the daily valley wind that dictates when you ride.
The Tribhuvan Highway and Daman, the old road nobody uses
The Tribhuvan Highway is Nepal's first road, completed with Indian assistance in 1956 and named for King Tribhuvan. It links Naubise, 25 km (16 miles) west of Kathmandu, with the Indian border at Birgunj, and the section that matters is the middle. Hetauda is 32 km (20 miles) from Naubise as the crow flies; the Tribhuvan Highway takes 107 km (66 miles) to get between them, in an unbroken sequence of climbs and descents over the Sivalik Hills.
The high point of the road is Daman, 77 km (48 miles) southwest of Kathmandu at 2,322 m (7,620 ft), which has arguably the finest Himalayan panorama accessible by road in Nepal — on a clear morning the view runs from Dhaulagiri in the west to Everest in the east. Since faster routes to the Terai opened, most freight has left this road, which is exactly what makes it good now. It is narrow, poorly surfaced in places and slow, and it is the single best day of tarmac riding within reach of Kathmandu.
The Siddhartha Highway through Palpa
The Siddhartha Highway is the other way between Pokhara and the Terai, 181 km (112 miles) from Siddharthanagar on the Indian border up through Butwal, Tansen and Syangja. Built with Indian financial assistance between 1964 and 1971 and opened in 1972, it carries about 34 bridges, the longest crossing the Kali Gandaki at Ramdi.
Nepali travellers largely avoid it in favour of the Prithvi Highway, for two honest reasons: it is a long chain of narrow curves, and the surface is poor. The Butwal to Palpa section runs through rocky terrain with frequent rockfall and a bad accident history. Riders read the same facts differently. If you want continuous cornering, hill towns like Tansen and far less truck traffic than the Prithvi Highway, this is where to find it — but ride it in daylight, in the dry, and watch the cutting above you as well as the road ahead.
The Araniko Highway to the Tibetan border
The Araniko Highway runs 112 km (70 miles) northeast from Kathmandu to Kodari on the Chinese border, built in the 1960s with Chinese assistance on an older yak track. It passes Dhulikhel at 1,585 m (5,200 ft), drops into the Panchkhal valley and then follows the Sun Kosi through increasingly steep country to Barabise and Tatopani.
Be honest about what it is. It is described as among the most dangerous highways in the country: the slopes above the final stretch are extremely steep and highly landslide-prone, the road was closed for 46 days by the Sunkoshi landslides in 2014, and it was cut entirely by the 2015 earthquakes before reopening that August. Ride it in the dry season and treat the section beyond Barabise as conditional rather than planned.
Seasons, permits and the practicalities
Season. The monsoon runs roughly June to September and it is the dominant constraint on riding in Nepal. Rain on steep, cut slopes produces landslides, and highways including the Prithvi and the Araniko are blocked repeatedly every year. The reliable window is October to April, with October and November giving the clearest mountain views after the rain has washed out the haze, December and January cold at dawn but fine by mid-morning, and February to April warm and increasingly hazy from dust and agricultural burning. Upper Mustang is the exception that stays open through the wet months.
Permits. Most of Nepal needs no permit at all. The restricted areas do, Upper Mustang most prominently, and those permits can only be applied for through a registered Nepali agency and come with a compulsory guide. Conservation area permits apply separately in the Annapurna region. Rates change; confirm current figures with your agency or the Department of Immigration rather than trusting a published number.
Licences and insurance. Bring a valid home licence for the class of machine plus an International Driving Permit, obtained before you travel. Rental agencies ask for both and traffic police do check. The bigger exposure is insurance: a great many standard travel policies exclude motorcycles or cap cover at 50cc, which excludes every rental in Nepal, and an evacuation from a mountain road here means a helicopter.
Rentals. The trade is concentrated in Thamel in Kathmandu and Lakeside in Pokhara. The default machine is a 400cc-class single such as a Royal Enfield Himalayan, with cheaper 150–250cc Indian-market bikes available for tarmac-only trips. Weekly rates for the bigger bikes run into the low hundreds of US dollars. Get the geographic scope of the rental in writing, check the tyres properly rather than glancing at them, and video the machine before you ride away.
Traffic culture. Left-hand drive, heavy trucks and buses overtaking on blind bends as routine practice, livestock on the carriageway, unlit vehicles after dark and pedestrians in the traffic lane. Ride in daylight only. A horn behind you is information rather than aggression; it usually means the vehicle is already committed to an overtake.
Gear notes for a country with no signage and patchy power
Two problems recur across every route above. The first is navigation. Diversions around construction and landslide clearance are unsigned or signed only in Nepali, mobile data drops in the deep valleys and disappears entirely above Kagbeni, and the alternative roads are village tracks that do not read as through routes on a map. Downloading the whole region before you leave the city, and running it on a display you can read in dust and hard sun, is the difference between a diversion and a lost afternoon — our offline navigation guide covers what to prepare, and a JADO S6 riding system keeps route and cameras on one screen so your phone stays in your pocket at checkpoints.
The second is that you are on your own with the machine. Rental tyres in Nepal are frequently closer to the wear limit than you would accept at home, construction sections throw loose chippings, and Mustang adds sharp rock and sub-zero mornings that move your pressures around. Our tire pressure guide explains what to set and check daily, and a TPMS sensor flags a slow leak while you are still upright. Lodge power on the hill routes is limited and often switched off overnight, so a bi-directional fast charger that draws from the bike is more useful here than another set of adapters.
FAQ
What is the best motorcycle route in Nepal?
For most riders it is the Kathmandu–Pokhara corridor ridden as a loop, out via the Prithvi Highway with detours to Bandipur and Gorkha and back over Daman on the old Tribhuvan Highway. For riders with more time and a bigger budget, the Kali Gandaki road into Upper Mustang is the standout, but it needs permits and a guide.
When should I ride in Nepal?
October to April. October and November are the best month for mountain visibility. Avoid the monsoon, roughly June to September, when landslides close highways with little notice. Upper Mustang is the exception and stays rideable in the wet months because it sits in the rain shadow.
Do I need permits to ride around Nepal?
Not for the main highways. Restricted areas such as Upper Mustang require a permit obtained through a registered Nepali agency, come with a compulsory licensed guide, and carry a per-person, per-day fee. Conservation area permits apply separately in the Annapurna region.
Do I need an International Driving Permit in Nepal?
Yes, together with a valid home licence for the class of machine. Rental agencies generally ask for both, police checks happen, and travel insurers treat the licence question as the first test of any claim. You have to obtain the IDP in your home country before you travel.
What bike should I rent in Nepal?
A 400cc-class adventure single such as a Royal Enfield Himalayan covers everything from the Prithvi Highway to the Mustang gravel. If you are staying on tarmac between Kathmandu, Pokhara and the Terai, a 150–250cc bike is cheaper and perfectly adequate. Whatever you take, check the tyres yourself before you accept it.
