“We” are the husband and wife team of Mbra and Andrea, we created Green Hill in 2006 and our vision was to build a conservation project that would help to protect Gunung Leuser National Park, it’s wildlife and human communities. What makes us unique is that our conservation work is funded by our ethical and sustainable tourism programme in which we take YOU, our conservation minded and adventurous visitors, on jungle treks in areas which are off the beaten track and well away from the busy tourist trails.

We specialise in ethical/sustainable jungle tourism by trekking routinely in remote areas and strictly following and actively promoting national park rules. We operate a “positive tourism” policy where a key component is the promotion of biodiversity and ensuring community involvement from the beginning. You can join us for a classic jungle trek in Bukit Lawang or go beyond the ordinary and let us take you to see the untouched jungles of Bukit Kencur, Tualang Gepang, Simpang Dua and Simolap Hotsprings. Because of our unique backgrounds and experience we can help you explore the wildlife and culture in a way that is not possible with conventional trekking companies.

 Mbra was born in Bukit Kencur and has been a guide for over 20 years (many with a scientific research project) but is now focusing on the management of Kuta Langis Ecolodge and farm…..our regeneration site in a converted palm oil plantation.
