Our ethical trekking rules

These rules apply on every trek, every day, whoever is guiding.

  1. We never feed orangutans or any wildlife. Feeding changes behaviour, spreads disease and teaches animals to approach people.
  2. We keep our distance. At least 10 metres from orangutans, and we step back if an animal comes closer.
  3. We never touch, call or chase animals. We watch quietly and let wildlife decide what happens.
  4. Small groups only. Six guests at most, so we leave a light footprint and you get real time with your guide.
  5. Licensed local guides. HPI-licensed guides from Bukit Lawang and Batu Katak, with an assistant and a jungle chef.
  6. Fair pay, every time. We follow official ITGA-HPI prices, so the whole team earns a professional wage.
  7. No trace left behind. We carry out all rubbish, use reusable water bottles and follow the national park rules.
  8. Sick guests stay out of the forest. Orangutans catch human illnesses easily, so we move your trek if you’re unwell.
  9. No guarantees, no staging. We will never lure an animal so you get a photo.
  10. 10% of every trek goes to our jungle fund. We buy land next to the national park to protect or replant it. See how.

How to tell if a jungle trek is ethical

Many companies in Bukit Lawang call their treks “ethical”. Use these signs to check before you book, with us or anyone else.

Red flagAn ethical trek does this instead
Guides carry bananas or fruit for orangutansNo food for wildlife, ever
“Guaranteed” orangutan sightingsHonest about chances
Groups of 10, 15 or moreSix guests or fewer
Guides call, whistle or bang treesQuiet tracking
Selfies next to orangutans10 metres away, no touching
Prices far below official HPI ratesFair wages for guides and cooks
Unnamed or unlicensed guidesLicensed guides you can meet
Rubbish left at campsEverything carried out

Ask any operator three questions: Do your guides ever feed the orangutans? How many people will be in my group? How much does the guide earn per day? An ethical company answers all three without hesitation. More in our guide to the real cost of cheap orangutan treks.

How to choose a responsible trekking company: check what it does, not only what its website says

Anyone can write “ethical” on a website. Look for proof instead:

  • Meet the guides online. A genuine company shows its guides by name and face, and you can look at their own social media profiles.
  • Check the company’s profiles. Do you see the same local team over the years and real guests, not stock photos?
  • Read reviews that name people. Real reviews mention guides by name and what happened on the trek.
  • Ask where the money goes. What does the guide earn? What stays in the village or goes to the forest?
  • Look for projects you can see. A named project, a place, photos and updates, not just a promise.

We’re happy to be checked. Meet our team on our About Us page, read our reviews, or message us on WhatsApp and ask us anything.

Ethical for people too

An ethical trek protects the people of the jungle edge as much as the wildlife.

  • Local team. Our guides, assistants and cooks come from Bukit Lawang and Batu Katak, so your trek pays local families directly.
  • Official wages. A guide earns a professional day rate, with more pay when the group is larger.
  • Village life, not a show. Guests can join a cooking class, a village tour or a visit to the local school, and we support local projects such as street-cat neutering.

Our jungle fund: 10% of every trek

Being ethical on the trail is only the start. We want to leave something behind for the forest, so 10% of the price of every trek goes into our jungle fund. The money is saved to buy land right next to Gunung Leuser National Park:

  • Where the land is still forest, we protect it, so it can never be cleared for palm oil.
  • Where it is already palm oil plantation, we replant native rainforest trees and let the jungle grow back.

The border between farms and forest is where we want to help.

Every piece of land next to the park gives orangutans more room and creates a buffer between forest and farms, which also reduces human-wildlife conflict. It is our long-term conservation project, and volunteers can join us to plant and look after the trees. Want to help or volunteer? Get in touch, or read our story.

Frequently asked questions

What is ethical jungle trekking?

Ethical jungle trekking means visiting the rainforest without harming wildlife or local people: no feeding or touching animals, keeping a safe distance, small groups, licensed local guides and fair wages for the whole team.

Is jungle trekking in Bukit Lawang ethical?

It can be, but not every operator is. Some guides still feed semi-wild orangutans to guarantee sightings. Choose a company that never feeds wildlife, keeps groups small and pays official HPI rates.

How can I check that a trekking company is really ethical?

Look past the website: find the guides’ own social media profiles, check the company’s profiles for the same local team over time, read reviews that name guides, ask what the guide earns and ask to see any community or conservation project.

Where does the money from my trek go?

It pays fair wages to our local guides, cooks and porters and covers park permits and food. On top of that, 10% of every trek goes to our jungle fund, which buys land next to Gunung Leuser National Park to protect it from palm oil or replant it as rainforest.

Will I definitely see orangutans?

No ethical operator can promise it. In Bukit Lawang the chance is very high; in Batu Katak the orangutans are fully wild and harder to find. Longer treks raise your chances. Read our Bukit Lawang orangutan trekking guide.

How fit do I need to be?

You’ll trek 6–7 hours a day on steep, muddy, humid trails. A reasonable level of fitness is enough for the 2-day trek; the 4-day and longer expeditions are more demanding.

Can I trek alone?

Yes. We match solo travellers with a group when we can. If no group is available, a solo supplement applies (€100 for most treks), or you can join a scheduled group trip with no supplement.

How much does an ethical jungle trek cost?

Our treks start at €120 per person for 2 days and 1 night, including guide, meals, camping gear and park permits. Much cheaper prices usually mean guides and cooks are underpaid.

How do I get to Bukit Lawang or Batu Katak?

Both are about 3.5–4 hours by car from Medan or Kualanamu Airport. We can arrange a private transfer when you book. See our transport guide.
