Treking near Landak River, located just 4km from Bukit Lawang. The hidden forests sit beside the river and overlook the Leuser National Park. Scarce of tourists, peaceful and diverse. Eco-Trekking here is a real experience. A great place to explore.

4 Day Combo EcoDiscover Trek, September 2019

 It was one of those lifetime trips that'll be in our hearts forever. We were super lucky and saw some of the rehabilitated Orangutans, Thomas Leaf Monkeys and my favourite was a family of Wild Orangutans that are in a secret spot only our guides knew about. I can't speak highly enough of Heri and Uncle Ian

Carly & Connor, Australia

2 Day Combo eco-discover trek, 
August 2022

.... their unique combo eco-trek - which doesn't only allow to spot semi wild and rehabilitated Orang-Utans in the Gunung Leuser Nationalpark but also truly wild ones in the adjacent property of Heri's grandma. ... If you are up to adventure, go for the 2-day-overnight COMBO trek - this one really differs to all the other 2 day overnight tours offered in Bukit Lawang, because you get to walk off in areas where no other groups trek and not in groups of up to 8 people

Yara, German

4 Day Jungle Trek, February 2020

 It was an absolutely incredible experience and one I will cherish forever. The trek itself was impeccably organized and the guides were fantastic. The wildlife was astonishing, especially the wild orangutans than we managed to watch
