Backpacking in Sumatra
🏆 Top pickregion ranked #4
By Johan Kruseman 🇳🇱 | Updated June 3, 2026

Everyone talks about Sumatra for orangutans and volcano selfies, but what actually matters once you land is how much time you’re willing to burn on buses, how rough you’re okay with things being, and how deep you want to go into real Indonesia. Sumatra sits on the far western side of the country, a huge, wild counterweight to polished Bali and Java. For backpackers, it’s a trade: cheaper rooms, fewer crowds, more raw jungle and village life, but slower, more chaotic transport and less hand-holding. Bukit Lawang and Lake Toba are the easy hits; Banda Aceh and the Mentawais feel like a different planet compared with Yogyakarta or Lombok. It’s less over-touristed, more “figure-it-out-yourself.” If you like your trips a bit scruffy and high-reward, Sumatra quietly ruins other islands for you.

✨ Why go?
Ranked #4 region in Indonesia
What sets this place apart

Backpackers flock to Sumatra for its incredible variety of landscapes. You can hike through lush jungles, chill on stunning beaches, and explore volcanic mountains—all without the hassle of constant relocation. This region offers a unique blend of nature and culture that’s hard to find elsewhere.

Transport is surprisingly flexible; you can hop on a bemo or rent a motorbike to navigate between towns and attractions at your own pace. This means you can truly embrace slow travel, soaking in the local vibe instead of rushing from one spot to another.

Plus, the chance to interact with diverse communities adds depth to your experience. Whether you’re sipping coffee in a local café or trekking to a remote village, every moment feels authentic. Sumatra isn’t just a destination; it’s a journey worth savoring.

💡 HighlightsTop highlights of Sumatra

  1. Lake Toba & Samosir Island — The world’s largest volcanic lake, a proper geological oddity with Batak villages clinging to its shoreline. Stay in a homestay on Samosir, watch traditional music and carved houses, rent a scooter and ride the rim for views you won’t get anywhere else. It’s dramatic, sociable, and soaked in local culture — still very much Sumatra, not “another lake.”
  2. Bukit Lawang & Gunung Leuser National Park — Jungle treks to see orangutans in the wild (not in cages) are the main draw, but the real win is the thick lowland rainforest, hornbills, and river-camp nights with local guides who know the forest. Trek lengths vary, so you can do a half-day orangutan walk or a multi-day deep jungle trip. Personal favorite: I’ve returned here more than once — nothing beats watching

  2. Bukit Lawang & Gunung Leuser National Park — Jungle treks to see orangutans in the wild (not in cages) are the main draw, but the real win is the thick lowland rainforest, hornbills, and river-camp nights with local guides who know the forest. Trek lengths vary, so you can do a half-day orangutan walk or a multi-day deep jungle trip. Personal favorite: I’ve returned here more than once — nothing beats watching a wild orangutan family move through the canopy at eye level.
  3. Mount Kerinci & Kerinci Seblat National Park — Indonesia’s highest volcano with alpine meadows, crater hikes, and rare rhododendron blooms; the trek is steep but rewarding and far less crowded than the usual volcano circuits. Add tea plantations and sleepy Kerinci villages for cultural contrast — you’ll meet people who live off the slopes.
  4. Mentawai Islands — World-class surf, stone-age-style longhouses, and an indigenous culture utterly different from mainland Sumatra. Getting here takes effort (boat or small plane), but you’ll be rewarded with reef breaks, pristine jungle, and the chance to visit traditional Mentawai settlements — surfing and anthropology rolled into one.
  5. Harau Valley (Lembah Harau) — Hidden gem: towering granite cliffs, plunging waterfalls, rice terraces and quiet homestays make this a low-key paradise for climbers and hikers. Locals picnic by the river; rock climbers find sharp routes; it’s scenic without the crowds of Bukittinggi. Great for a relaxed couple of days of walking and watching village life.
  6. Nias Island (South Nias) — Famous for hollow-point surf and the extraordinary “Fahombo” stone-jumping ritual — a living cultural performance you won’t see elsewhere. Nias has wooden longhouses, unique dances, and a strong community vibe; go during a festival for the best cultural immersion. Access needs planning but the island’s personality is worth it.
  7. Tesso Nilo National Park — Hidden gem: a lesser-known lowland forest and peatland in Riau where you can still find wild elephants, orangutans, and hornbills without the crowds. It’s raw, muddy, and fragile — visiting with trusted local guides helps support conservation and local communities. Expect basic facilities and a real off-the-beaten-path feel.
  8. Bukittinggi & Sianok Canyon (Minangkabau heartland) — Town life, lively pasar markets, and the iconic Minangkabau rumah gadang architecture make this a cultural hub. Walk the Sianok Canyon at sunrise, haggle at the local market for padang-style snacks, and go taste the real rendang cooked by local families. It’s a compact, tactile way to understand West Sumatran culture.
  9. Lake Maninjau — Hidden gem: quieter than Lake Toba but every bit as scenic — a volcanic caldera lake ringed by small villages and dramatic viewpoints. Rent a motorbike and descend switchbacks into the lake at dawn, stop for kopi and book-club-like chats in tiny warungs, and cycle the rim if you like a good adrenaline-fueled descent. Peaceful, photogenic, and very local.
  10. Way Kambas National Park — Elephant encounters, conservation camps, and night safaris in southern Sumatra make this a great place to see Sumatran elephants and learn conservation stories up close. The park has community-run initiatives and simple ranger-run tours — not glitzy, but meaningful if you care about wildlife survival and supporting local conservation efforts.

Day 5: Off-Path Reward: Sipiso-Piso Waterfall
On your way back to Medan, take a detour to Sipiso-Piso Waterfall. It’s a stunning sight that adds a splash of adventure to your return trip. The waterfall is one of the tallest in Indonesia, and the views are breathtaking.

The must-do day? Day 2 in Bukit Lawang. The trek is not just about the orangutans; it’s about immersing yourself in the wild heart of Sumatra. That experience will stick with you long after you leave.

🌤️ When to go?When to go for the best experience


  • Weather: The dry season from May to September is your golden window. Expect less rain, which means trails stay firm and rivers aren’t raging. The wet season (October to April) can turn your trek into a soggy slog, with daily downpours and muddy paths.

  • Temperature: Sumatra stays warm year-round, averaging 26-32°C (79-90°F). Nights cool down to around 22°C (72°F), perfect for camping without freezing your toes off. The dry season feels more comfortable with lower humidity.

  • Daylight Hours: Roughly 11-12 hours of daylight year-round, thanks to its equatorial spot. Early starts are key—hit the trail at dawn to maximize light and avoid midday heat.

  • Crowds: Peak dry months attract more tourists, especially July and August. If you want fewer people, aim for shoulder months like May or September—still

  • Crowds: Peak dry months attract more tourists, especially July and August. If you want fewer people, aim for shoulder months like May or September—still dry but with a quieter vibe.

  • Seasonal Activities: Wildlife spotting and jungle trekking are best in the dry season when animals are more active and trails accessible. Surfing peaks from June to September on the west coast, so plan accordingly if that’s your jam.

  • Price Fluctuations: Expect higher prices during the dry season, especially in popular spots like Bukit Lawang. Off-season offers better deals on accommodation and tours but brace for rain interruptions.


Pro-tip: Book your flights and lodgings for late May or early September to snag dry weather, fewer crowds, and better prices—a sweet spot most tourists overlook.

  • Ferries: Essential for island hopping. Prices vary widely, from $2 to $20 depending on the route. They usually run from dawn until dusk. The experience can be scenic, but be ready for delays; it’s all part of the adventure.


  • Car Rentals: If you crave freedom, consider renting a car. Prices start around $30 per day. It’s the best way to explore at your own pace, but be prepared for some rough roads and local driving styles.

Dive into Rendang, a rich, slow-cooked beef dish that’s a symphony of spices, or try Soto Padang, a fragrant soup that warms you from the inside out.

We 💚 feedbackFinal thoughts on visiting Sumatra

Sumatra’s wild heart beats in its jungles and volcanic landscapes. You’ll find jaw-dropping beauty and rich culture that feels untouched. But, let’s be real: the infrastructure can be a challenge. Expect bumpy roads and limited services. Embrace the chaos, and you’ll uncover experiences that stick with you long after you leave. It’s the kind of adventure that makes you feel alive.

✈️ When did I visit Indonesia?
As part of my 1.5 year travel around the world trip, I visited Indonesia twice (and it was worth it. First in September 2015 and a bit later again in January and February 2016.
