West Sumatra: the Minangkabau highlands and the Mentawai coast

West Sumatra is where Indonesian food comes from, at least in the version the rest of the world knows. Rendang, sate Padang, gulai kepala ikan: the dishes that anchor a nasi Padang spread were codified here, in a province where cooking is a serious civic matter and every town claims the best version of something.

It is also the most vertical province on Sumatra. The road from Padang climbs through the Anai valley into a highland of volcanoes, rice terraces and Minangkabau houses with buffalo-horn roofs, then drops through 44 hairpins to a crater lake. And two hours offshore, the Mentawai islands run on a different clock entirely.

Padang is a food city first

Minangkabau International Airport sits at Ketaping, about 30 kilometres north of Padang, and the drive into the city takes 30 to 45 minutes depending on traffic. Most travellers treat Padang as a transfer point. That is a mistake, because the city eats better than almost anywhere in Indonesia and does it for very little money.

A Padang restaurant works on a simple system: you sit down, and a waiter stacks a dozen small plates on the table whether you ordered them or not. You eat what you want and pay for what you touch. Rendang is the famous one, but look for gulai tunjang (cow tendon in coconut curry), dendeng balado (thin dried beef with chilli) and gulai kepala ikan kakap, a whole snapper head in a yellow curry that is best eaten with your hands and a stack of napkins.

The other Padang institution is the coffee shop. Teh talua, tea whipped with egg yolk and sugar, is the local order, and the espresso culture that arrived with students has stuck. Spend one night here before going uphill; the highlands are close enough that there is no reason to rush.

Bukittinggi, Jam Gadang and the Sianok canyon

The road from Padang to Bukittinggi crosses the Anai valley, a gorge of rainforest and waterfalls that is the most photographed stretch of road in Sumatra. The climb takes about two hours, and the temperature drops ten degrees by the time you reach the town at roughly 930 metres.

Jam Gadang, the clock tower in the middle of Bukittinggi, was a gift from the Dutch in the 1920s and has since survived a change of roof shape: the original Dutch crown was replaced with a Minangkabau buffalo-horn roof after independence. It is the town's meeting point, and the market below sells songket, embroidery and the local brittle crackers.

Five minutes' walk away, the Sianok canyon drops 100 metres below the town, with a river at the bottom and a network of paths and old Japanese tunnels cut into the rock. The canyon is quiet in the early morning and crowded at sunset. Fort de Kock, the Dutch fort on the ridge, is connected to the town by a pedestrian bridge and gives you the whole geography in one view.

Harau Valley and the road to Lake Maninjau

Harau Valley sits about 40 minutes east of Bukittinggi, near Payakumbuh, and it is the single most dramatic landscape in the province. Granite cliffs rise 100 to 150 metres straight out of the rice fields, with waterfalls dropping after rain and gibbons calling from the forest above. There are homestays at the valley floor and a few short walks to the waterfalls; it is a place to sleep rather than a place to tick off.

From Bukittinggi, the other great road is the descent to Lake Maninjau. The old route drops roughly 600 metres in 44 numbered hairpins, known as Kelok 44, each turn with a view over the crater lake. A newer, straighter road now carries most traffic, which means the old road is often nearly empty. Take the old one if your driver is willing.

Maninjau itself is a caldera lake about 17 kilometres long, ringed by villages and hot springs. The water is warm, the fish farms are everywhere, and the best thing to do is rent a motorbike and ride the full loop in a morning. Stop at the hot springs at Paninjauan and eat at one of the lakeside warungs that grill tilapia from the ponds behind the kitchen.

The Mentawai islands

The Mentawai chain lies 100 to 150 kilometres off the coast, and it is the reason surfers know West Sumatra at all. The waves around Sipora, North Pagai and South Pagai are world-class: long, fast left-handers over shallow reef, served by charter boats from Padang. A surf charter is the expensive way to do it and the only way to hit multiple breaks in a week.

The cheaper route is the public ferry from Padang to Tuapejat on Sipora, which takes several hours and runs on a schedule that changes with the weather. From Tuapejat there are simple homestays and boats to nearby breaks. For the interior, ferries also run to Muara Siberut, the main town on Siberut, where the rainforest and the traditional Mentawai longhouses are the attraction rather than the surf.

Be honest about what you are booking. Mentawai is not Bali: medical facilities are basic, the sea crossings are rough in the wet season, and a surf trip here depends on swell and local boatmen. Go with a licensed operator, bring your own reef-safe supplies, and respect that the villages you pass through are not a theme park.

The coast: Bungus, Pagang and the road south

South of Padang, the coast road runs through Bungus to a string of small islands that make an easy weekend from the city. Pulau Pagang is the most popular: a 30-minute boat ride from the mainland, a white sand spit, shallow reef and a handful of warungs. Pulau Sikuai, further out, has a resort, and the surrounding water is clearer than anything you will find near Padang.

This coast also has the province's second-best food story: grilled fish at the beach warungs, served with sambal and rice, at prices that make the airport restaurant look absurd. The road continues south towards Painan and the Mandeh bay, where the hills meet the sea and the boat trips are cheaper and less organised than anything on the tourist trail.

What it costs

West Sumatra is one of the cheapest provinces in Indonesia for travellers. A clean guesthouse room in Bukittinggi costs roughly IDR 250,000 to 450,000, and a similar amount buys a bungalow in Harau or on the Maninjau rim. A car with driver for a day of highland transfers is usually IDR 700,000 to 1,000,000, fuel included; agree the route and the total before you leave.

Food is where the province shines. A full nasi Padang lunch for two, with several dishes and drinks, rarely tops IDR 100,000. The Mentawai ferry is the big variable: prices differ between fast and slow boats and between locals and foreigners, and the ticket office is the only reliable source. Bring cash for the highlands and the islands; ATMs exist in Bukittinggi and Padang and become scarce everywhere else.

When to go, and a week that works

West Sumatra is wet most of the year. The driest stretch is roughly June to September, which is also the best time for the Mentawai and the highland roads. Rain in Bukittinggi usually arrives in the afternoon and clears by evening; the coast can be grey for days in November and December.

The province sits on the Sumatran subduction zone and has a history of large earthquakes, including the 2009 Padang quake. Buildings are built for it, but know the drill: if the shaking is long or the sea pulls back, go inland or uphill immediately. This matters most on the coast and the islands.

• Days 1 and 2: Padang — eat, then the coast at Bungus and Pulau Pagang.
• Days 3 and 4: Bukittinggi — Jam Gadang, Sianok canyon, Fort de Kock, Pandai Sikek wood carvings.
• Day 5: Harau Valley — sleep under the cliffs, walk to the waterfalls.
• Day 6: Lake Maninjau — Kelok 44, the lake loop, hot springs.
• Days 7 to 10: optional Mentawai extension — ferry to Tuapejat or a surf charter from Padang.

Questions people actually ask

Is Padang worth more than one night?

Yes, if you care about food. The city has the best nasi Padang in Indonesia, a working waterfront and easy access to the islands at Bungus. One full day plus a night is enough to eat well and see the coast.

How do I get to the Mentawai islands?

Public ferries leave Padang for Tuapejat on Sipora and Muara Siberut, with schedules that change with weather and season. Surfers usually book a charter boat from Padang instead, which is faster and far more expensive.

Do I need a guide in the highlands?

No. Bukittinggi, Harau and Maninjau are easy to do independently with a rented motorbike or a car and driver. A guide is only necessary for serious trekking or for the Mentawai interior.

Is West Sumatra safe?

It is safe for ordinary travel. The real risks are road traffic on the winding highland roads and earthquakes. The coast and islands have tsunami evacuation routes; take them seriously.
