Indonesia and Sumatra


Sumatra (also spelt Sumatera) is the sixth largest island in the world (approximately 470,000 km²) and is the largest island entirely in Indonesia.

The island is home to a host of species including Sumatran Pine, Rafflesia arnoldii (world's largest individual flower), Titan arum (world's tallest and largest inflorescence flower), Sumatran Tiger, Sumatran Orangutan, Sumatran Rhinoceros, Sumatran Elephant, Sumatran Striped Rabbit, Malayan Tapir, Malayan Sun Bear, Bornean Clouded Leopard and many birds and butterflies.

The island includes more than 10 National Parks, including 3 which are listed as the Tropical Rainforest of Sumatra World Heritage Site. Gunung Leuser National Park is the area in which our treks and expeditions are centred. Indonesia is second only to Brazil in its holdings of tropical forests; ten percent of the world's total rainforest grows on the Indonesian archipelago of 13.677 islands.

Gunung Leuser National Park and Bukit Lawang

Gunung Leuser National Park is one of the biggest national parks in Indonesia (950,000 hectare). The biodiversity is breathtaking and approximately 700 different species of animals (320 birds, 176 mammals and 194 reptiles and amphibians) live in this region. Of the 10,000 plant species recorded in the West Indo-Malayan region, it is estimated that 45% are found in the Gunung Leuser ecosystem.

Bukit Lawang is located about 3 hours drive from Medan. Our base is situated in Bukit Lawang and it is the main access point for Gunung Leuser National Park. In 1973 the Bohorok Centre for ex-captive and refugee Sumatran orangutans was established in 1973 by two Swiss zoologists, Regina Frey and Monica Boerner. Many of the rehabilitated females have conceived and given birth in the forest. This means the centre has increased the orangutan population as well as giving the infant a chance to grow up in a protected forest area.


We can arrange all types of accommodation to suit all budgets.

Most of the guest houses and rooms in Bukit Lawang are by the side of the Bohorok river and cwith stunning views of the jungle. It is not uncommon to sit eating your lunch and find yourself being observed by an orangutan from the other side of the river.

Most rooms are en suite. Many rooms have their own balcony and hammock, giving you an amazing vantage point of the river and the surrounding jungle.


We can also arrange for you to stay outside of the tourist area, with one of our guides and his family. Learn how to cook traditional Indonesian food and achieve a real sense of what it means to live as a Sumatran in this area.

It is also possible to help out with farming in the adjacent padi fields whilst taking in magnificent views of the surrounding National Park.



Accommodation during trekking expeditions

On an overnight trek we all camp together in a tent sized to the number of people. It is quite basic, but more than adequate and a key part of the jungle camping experience.

We recommend you bring a sleeping mat and a sleeping bag if you have them. If you are already on the road we might have a spare one we can lend you as with other equipment which we can give you more details of when you book.

If you would prefer not to share a tent whilst on the trek we have a few dome tents which can be hired.

Getting to Medan, Sumatra

We can provide private transportation from Medan to our base or to the other tour destinations. If you are flying from Europe or US you should be able to book a flight direct to Medan . You may have a short stopover in Kuala Lumpur or Singapore . At the time of writing Thai Airlines and Malaysian airlines offer reasonably priced flights.

If you are already travelling, you can fly direct to Medan from Jakarta , Penang, Kuala Lumpur or Singapore . Air Asia offers some very cheap deals.
Our Guides

We employ our guides locally. All are fully licensed, highly experienced and English speaking. Local weather conditions or the general unpredictability of Indonesia may necessitate adjustments to the tour itinerary or route. We fully trust our guides to make balanced and reasoned decisions to ensure your safety and enjoyment.

All of our guides follow a strict code of no contact with the orangutans. Some of our guides are also involved with research and conservation projects based in the area and are fully aware of the importance of following conservation guidelines, both to protect the jungle and the wildlife indigenous to this region and also to set an example to other guides and visitors.


The purchase of travel and medical insurance is strongly recommended for all overseas travel. Please confirm with your insurer that your policy meets your needs.

Visas and red tape

Most Western nationals are eligible for a 30 day visa on arrival at a cost of $35. If you are planning on staying longer, it is possible to apply for a 60 day tourist visa from an Indonesian embassy outside of Indonesia . We strongly recommend you contact your Indonesian embassy or General Consulate to check your visa status.


Immunization is strongly recommended for visits to Sumatra , in particular for typhoid, hepatitis A and B, tetanus and polio. We recommend that you consult your GP before your trip.

The current situation

Unfortunately the Gunung Leuser ecosystem, which extends beyond the boundaries of the National Park, is seriously threatened. Environmental groups are concerned that rapidly expanding palm oil plantations, partly driven by ambitious plans for biofuels, are damaging the country's rainforests. Ironically, biofuels are likely to speed up global warming as they have encouraged farmers to burn tropical forests that have absorbed a large portion of greenhouse gases.

Greenpeace says Indonesia had the fastest pace of deforestation in the world between 2000-2005, with an area of forest equivalent to 300 soccer pitches destroyed every hour. We hope that our local initiative can add to the momentum towards local people conserving their own environments through enhancing an appreciation of wildlife and ‘wild' environments through education and work opportunities for the local people.

Expedition Jungle is fully inclusive of the local population. Our viability depends on the knowledge of our people as well as the natural and cultural environment. We also hope that by exposing tourists to the beauty of the rain forest and the current issues we can also generate outside support and contribute towards highlighting the plight of Sumatra 's rainforests before it is too late.
