The RN7: Madagascar's classic road trip, stop by stop

The RN7, the Route nationale 7, runs south from Antananarivo to Toliara (Tulear) on the south-west coast, a little over 920 km by its kilometre posts. It's Madagascar's classic road trip: highland rice terraces, the rainforest of Ranomafana, ring-tailed lemurs at Anja, the sandstone of Isalo, then spiny forest and the sea. It's paved and slow. Give it about a week from the capital to the coast if you want time for the parks, then consider flying back.

Our Classic South is an RN7 tour with time to enjoy it: 11 days from €1,730 per adult, private, with your own vehicle and driver-guide. The Ultimate Madagascar Adventure drives the same road north at the end of three weeks. Here it is as the Classic South runs it.

How long is the RN7, and what is the road like in 2026?

The kilometre posts start in the capital. Antsirabe is at about km 170, Fianarantsoa about 410, Ambalavao about 460, Ihosy about 600 and Ranohira, the town for Isalo, about 700. It ends at Toliara's seafront around km 926.

It's tarmac all the way, in very different states. Reports of repairs don't make every stretch fast. L'Express de Madagascar documented severe delays on the southern RN7 in late 2025, and conditions can change again with works and rain. Confirm the driving plan close to departure.

Rough planning distances and driving allowances, without long stops. These aren't a timetable:

• Antananarivo to Antsirabe: about 170 km, usually four to five hours.
• Antsirabe to Ranomafana: five to seven hours, through Ambositra.
• Ranomafana to Fianarantsoa: about 65 km on a narrow, winding road.
• Fianarantsoa to Ambalavao: about 55 km, an hour or a little more.
• Ambalavao to Ranohira: roughly 220 to 240 km, usually four to six hours.
• Ranohira to Toliara: 250 km, about five hours by Madagascar National Parks' reckoning, nearly eight at the worst of 2025.

Ranomafana: the rainforest just off the road

Ranomafana isn't on the RN7. You turn east off it north of Fianarantsoa into steep mountain forest, the one big rainforest on the way south, and the Classic South gives it two nights: a night walk along the forest edge, then a morning in the park looking for the golden bamboo lemur and lunch at Centre ValBio, the research station. Our Ranomafana guide covers the trails and fees.

Fianarantsoa and Ambalavao: the old town, the paper and the zebu market

Day 6 rejoins the RN7 and stops in Fianarantsoa, the big town of the southern highlands, for its old upper town: steep cobbled lanes, houses packed tight, a lot of churches and a view over the city. The World Monuments Fund, which put it on its 2008 watch list, calls it the only place in Madagascar where nineteenth-century buildings still stand together as a whole.

Ambalavao is about 55 km on. Its Antemoro paper is made from the bark of a local bush with flowers pressed into it, and the Classic South visits the workshop after lunch.

The zebu market here is the country's second biggest, after Tsiroanomandidy, says Rough Guides. It starts before dawn on Wednesday and runs until Thursday morning, with herds walked in from as far as Toliara. The Classic South sleeps in Ambalavao on day 6, so if that night is a Tuesday or a Wednesday you can go early next morning. Our trips start on any date, so ask us to time it.

Ihosy, the Horombe plateau and Isalo

On day 7 the country changes. Ihosy, about 140 km past Ambalavao, is the de facto capital of the Bara, zebu herders whose cattle you'll often meet on the road. Then the RN7 crosses the open grassland of the Horombe plateau, long and nearly empty, until Isalo's sandstone rises out of it.

At Ranohira the Classic South has a free afternoon and sunset at the Window of Isalo, then spends day 8 in the park among canyons and natural pools. Although swimming appears on the published trip, the CDC advises avoiding untreated fresh water in Madagascar because of schistosomiasis. Ring-tailed lemurs and sifakas are often seen on the trails. Our Isalo guide compares the walks.

The travel advice sharpens here. At the time of writing, the UK Foreign Office calls the triangle between Ihosy, Toliara and Fort Dauphin tense, with greater risks at night, and advises a recognised tour operator there. It reports attacks by cattle raiders in the commune of Ilakakabe, near Isalo, though not on tourists. More in Is Madagascar safe?

Ilakaka, Zombitse and the road to the coast

Day 9 is the drive to the sea. The first town after Ranohira is Ilakaka, which changed for good in 1998, when one of the world's biggest sapphire deposits was found around it. The rush built a main street of stone-buying counters. Drive through by day, and if you stop, stay on the main street with your driver-guide. Unless you know stones, look rather than buy.

Further on, the road runs beside Zombitse-Vohibasia National Park, where Madagascar National Parks counts eight lemur species and Appert's tetraka, a bird found in this corner of the south-west and almost nowhere else. Circuits take 30 minutes to two and a half hours, and dawn is best for birds. It isn't on the Classic South's plan, so ask us whether a walk fits.

Sakaraha to Toliara was the worst stretch of the RN7 in late 2025, so leave early. Near the coast the country turns to spiny forest and baobabs.

How many days does the RN7 need?

A direct drive would mean several long days. Give the stops their own nights. Allow two nights at Ranomafana, one at Ambalavao for Anja and two at Ranohira for Isalo. That makes a week to the coast, the Classic South's pace on days 3 to 9, then a flight back from Tulear instead of two or three more days on the same road. Any faster and you'll see the RN7 mostly through the windscreen. More in Madagascar itineraries.

Why you shouldn't drive the RN7 at night

The UK, Canada and France all advise against driving after dark. The Foreign Office says vehicles often have no lights and few roads are lit, and France lists what you meet on the tarmac: people on foot, broken-down vehicles, herds of zebu and carts. The UK also reports frequent armed robberies on main roads, particularly at night and outside the major towns.

Plan the long legs to start early enough to finish before dark. A five-hour leg that turns into eight is how people end up driving in the dark. With your own driver-guide you set the departure time, so the long days can end in daylight.

Self-drive or a driver-guide?

Of Madagascar's long roads, the RN7 is the most realistic one to drive yourself: it's paved, though the right vehicle still depends on current conditions and side trips. Traffic drives on the right, and you need your licence and an International Driving Permit, which UK drivers must get before they leave home.

Against it: potholes, trucks, map apps that don't know which stretch is under repair, and the southern third, where the Foreign Office advises a recognised tour operator. A one-way hire usually means paying for the car's drive back too. Our guide to getting around has the costs.

A driver-guide plans each day around the road and does the talking in Malagasy or French. For a first time on the RN7 we'd take one. We would say that, of course.

The best months for the RN7

• April and May. The rains tail off in April, and May is dry and mild before the busy months.
• June to August. Dry and cool, and the busiest months. Highland nights are cold, while Toliara stays in the high twenties with almost no rain. Humpback season on the wider south-west coast begins around June; Anakao is a documented departure point.
• September to early November. Our pick: warming up, ring-tail babies about and the main rains still to come. Isalo is hot by October, so walk there early.
• December to March. The rains. Ranomafana is very wet, France warns against Isalo's canyons in storms, and the Foreign Office puts cyclone season at November to April. We'd only drive the RN7 then if those are your only dates.

Adding Andasibe or Andringitra

• Andasibe. It's 140 km east of Antananarivo on the RN2, not the RN7, but the Classic South starts there because it's the place to hear the indri. Without it, the trip is two days shorter. See our Andasibe guide.
• Andringitra. Granite peaks 47 km off the RN7 from Ambalavao, on a track Madagascar National Parks says is hard going from November to March. Pic Boby, at 2,658 m, needs at least two days of trekking plus time for the approach. Extra hiking days can be discussed between Ambalavao and Ranohira; our Andringitra guide distinguishes valley walks from the summit trek.
