Sumatra is the sixth-largest island on earth, and it feels nothing like Bali. Distances are huge, the roads are slow, and the reward is a landscape still dominated by volcanoes, rainforest and highland lakes. Orangutans live in the jungle near Bukit Lawang, the Batak people farm the shores of the world’s largest volcanic lake, and the Minangkabau of West Sumatra run one of the largest matrilineal societies on the planet. It is also where rendang and nasi Padang come from.
This hub links the destination guides we have for the island and explains how they fit together on a route.

Getting to Sumatra and Getting Around
Most visitors arrive at Kualanamu International Airport (KNO) near Medan. Flights from Bali take approximately 3.5 hours (from about IDR 500,000-900,000), and Jakarta to Medan is roughly 2.5 hours. Medan is also linked to Kuala Lumpur and Singapore. Our Medan airport transfer guide covers the road into town.
The other main gateway is Minangkabau International Airport (PDG) in Padang, which makes a natural exit point for a one-way route. Flying Medan to Padang takes about 1.5-2.5 hours and costs approximately IDR 400,000-700,000 as of 2026. The overland alternative via Bukittinggi is 12-14 hours. For anything longer than a short hop, we fly.
Local legs are by minibus or hired car with driver. Berastagi to Lake Toba is about 3 hours by minibus (approximately IDR 30,000-50,000), and Padang to Bukittinggi is about 90 minutes (IDR 25,000-40,000). Ferries from Parapat to Tuk Tuk on Samosir take around 30 minutes.
North Sumatra: Medan, Bukit Lawang and Lake Toba
Medan is the island’s biggest city and most travellers’ first stop. Tjong A Fie Mansion (approximately IDR 35,000) and Maimoon Palace (approximately IDR 5,000) are the best colonial-era sights, and the durian stalls on Jalan Semarang are the reason foodies come. Read our Medan food guide and where to stay in Medan before you land.
Bukit Lawang sits on the edge of Gunung Leuser National Park, part of the Tropical Rainforest Heritage of Sumatra UNESCO World Heritage site. Guided treks run approximately IDR 200,000-350,000 for a half day and IDR 350,000-600,000 for a full day as of 2026. Our orangutan trek guide explains how to choose a guide and what sightings to expect.
Lake Toba is a crater lake roughly 100 kilometres long, formed by a supereruption about 75,000 years ago. Samosir Island, in the middle, is the traveller hub, with Tuk Tuk as the base, and stone sarcophagi at Tomok, the stone chairs at Ambarita and the longhouse complex at Simanindo as the main Batak sights. Rooms in Tuk Tuk run from approximately IDR 100,000-200,000 for budget bungalows to IDR 200,000-400,000 for lake-facing mid-range. See where to stay at Lake Toba, the Lake Toba things to do guide and our Lake Toba food guide.
Between Medan and Toba, the Karo highlands around Berastagi offer the Sibayak volcano hike, usually done with a guide (approximately IDR 150,000-250,000).
West Sumatra: Padang and Bukittinggi
Padang is the Minangkabau capital and the home of nasi Padang, where a full mid-range spread costs approximately IDR 50,000-100,000 per person. Beyond eating, there is the Adityawarman Museum, the Malin Kundang rocks at Pantai Air Manis, and access to the Mentawai surf trips. Start with the Padang guide, then the Padang food guide and where to stay in Padang.
Bukittinggi, about 90 kilometres north, sits above Sianok Canyon with the Dutch-era Jam Gadang clock tower at its centre. The canyon rim walk is free, and a guided canyon-floor walk costs approximately IDR 100,000-200,000. Fort de Kock is about IDR 10,000. See where to stay in Bukittinggi.
Sample Routes
Our two ready-made routes cover most trips:
- Sumatra Adventure: 10 days from Medan to Padang via Bukit Lawang, Berastagi, Lake Toba and Bukittinggi, budgeted at roughly IDR 4,000,000-8,000,000 (USD 250-500) for budget travellers as of 2026.
- Sumatra Jungle Adventure: a jungle-focused version built around Bukit Lawang and the orangutan treks.
When to Go
May to September is the drier season in North Sumatra and best for trekking and volcano views; it also overlaps with durian season (about June to September). West Sumatra gets rain through the year. December to March is the wettest stretch almost everywhere, with muddier trails and cloudier summits. Sumatra has fewer tourists than Bali in every month, so book flights early rather than rooms.
Where to Stay
Medan, Lake Toba, Padang and Bukittinggi each have a dedicated stay guide linked above, with price bands by area. If you have not picked a base yet, search hotels across Sumatra on Booking.com to compare cities side by side, then narrow to a town.
Book Tours
Guided trips save time on this island because transport is slow. Browse Sumatra tours on GetYourGuide, or go city by city with Medan tours and Lake Toba tours. Take travel insurance with medical evacuation cover as well; many Sumatran trails are remote.
