About the Expedition
A serious jungle journey for active travellers
This five-day expedition takes you deeper into Gunung Leuser National Park than a standard overnight trek. The route may pass through the Jambur Batu, Landak, and Bohorok river landscapes, with long days of hiking across hills, streams, muddy paths, and remote rainforest terrain.
Your certified local guide and expedition team will help you search responsibly for orangutans, primates, birds, reptiles, insects, and signs of other wildlife. You will also learn about rainforest ecology, medicinal plants, local navigation, and practical camp life.
Rare animals such as Sumatran tigers live in the wider ecosystem, but sightings are extremely unlikely and can never be promised. Wildlife observation always happens at a respectful distance.
- Minimum two and maximum seven guests
- Certified English-speaking guide and expedition support team
- Four nights in simple riverside jungle camps
- Meals, fruit, snacks, and drinking water during the trek
- Traditional rafting return towards Bukit Lawang

Each guest receives a 1.5-litre bottle of drinking water. The guide refills bottles at camp using boiled water. Meals, fruit, and snacks are prepared by the expedition team.
Clothing and footwear
Wear lightweight, breathable, quick-drying clothes. A dry long-sleeved layer is useful at night. Choose broken-in trekking shoes with secure grip for mud, roots, and slippery paths.
Fitness and difficulty
Good fitness, balance, and confidence on natural terrain are required. Expect long walking days, steep climbs and descents, river crossings, high humidity, and simple camp conditions.
Responsible wildlife rules

Weather and route changes
Rain is normal in the rainforest. Routes, campsites, walking times, swimming, and rafting may change because of rainfall, river levels, fallen trees, wildlife activity, or other safety considerations.
Wildlife sightings
All animals live freely in their natural habitat. No sighting can be guaranteed. Five days provide more time to search, but quiet behaviour, animal welfare, and responsible distance always come first.
