North Sumatra
Lake Toba
The caldera left by a super-eruption about 74,000 years ago is nearly 100 kilometres long. Come for the scale, stay for the quiet.
Region 01 / 07
Sumatra
A volcano the size of a country, a lake with an island inside it, and a highland culture that kept its own architecture. Sumatra is the long way round — and that is the point.
9 days
Medan in, Padang out
May to October
The shape of the trip
One island, two very different journeys
Sumatra runs more than 1,700 kilometres along the western edge of Indonesia, held together by the Bukit Barisan range. The north is Batak country: Lake Toba, stone tombs and the rainforest of Gunung Leuser. The centre-west is Minangkabau: matrilineal clans, buffalo-horn roofs and a crater lake ringed by hairpins.
Most travellers pick one half. The two fit together if you have nine days and don't mind a flight in the middle. What you will not find is a fast train: outside the Medan airport link, Sumatra moves by road, and the road is part of the trip.
Don’t miss
Four places that justify the road
Each one is a half-day or more. None of them are day trips from Medan.
North Sumatra
Samosir
Batak villages on Samosir
Tongkonan houses, carved stone tombs and a church on every ridge. The island is the size of Singapore and considerably slower.
Aceh border
Gunung Leuser
Orangutans, gibbons and one of the last great lowland rainforests in Southeast Asia. Bukit Lawang is the usual base.
West Sumatra
Maninjau & Bukittinggi
A crater lake at the bottom of the Kelok 44 road, with the Minangkabau capital an hour away and the food worth the detour alone.
Practical
When to go, how to move
01
When to go
May to October is the drier half of the year across most of the island. The highlands are cool year-round: 15–20°C at night around Toba and Berastagi. December to March is wet, especially on the west coast, and the roads pay for it.
02
Getting there
Kualanamu (KNO) serves Medan with direct flights from Jakarta, Kuala Lumpur and Singapore. Minangkabau (PDG) serves Padang. Silangit (DTB) is the small airport beside Toba, useful if you want to skip the drive from Medan.
03
Getting around
Long-distance buses are frequent and cheap; the Medan–Bukittinggi run is a full day. A car with a driver costs more but stops where you want. The Parapat–Tuk Tuk ferry is the classic way onto Samosir. There is no intercity railway.
A route that works
Nine days, Medan to Padang
01
Medan
Land, eat, sleep near the old town. The last big city for a while.
02
Bukit Lawang
Three hours by road. A half-day walk in Leuser with a licensed guide; the orangutan feeding platform is not a zoo, but it is busy.
03
Berastagi
Karo highlands, fruit markets and a sunrise climb of Sibayak if the weather holds.
04
Samosir
Ferry from Parapat to Tuk Tuk, then a scooter loop past Ambarita, Simanindo and the hot springs.
05
Bukittinggi
Fly Medan to Padang, then climb into the highlands. Market, canyon, and the road down to Maninjau.
06
Padang
One night near the coast, a last plate of Padang food, and the airport in the morning.
