Your activities in a nutshell

Orangutan Sanctuary

A highlight and extreme privilege of our retreat is touring Samboja Lestari Orangutan Sanctuary. Samboja Lestari (translated as ” Samboja Forever”) is currently a home to over 200 orangutans that have been released into 6 islands around the lodge. Our detailed tour, will get you one-of-a-lifetime opportunity to deepen your orangutan knowledge but also observe the behaviour of rehabilitated individuals living within the complex.

Sungai Wain Full Day Trek

Within a protected forest area there are around 80 orangutans and a home for Malayan sun bears, proboscis monkeys, 242 species of birds (9 species of hornbills!) and countless other species. Upon arrival we meet our local guide and start searching for all those beautiful creatures.

Tree planting

It takes a lot of knowledge to plant trees properly, finding the best locations regarding amount of sun, water needs, proper soil balance and nutrients, etc. It is very educational and you will be able to experience for yourself the value of the local workers.

Sun bear Sanctuary

The BOS Foundation also looks after a number of sun bears, smallest bears in the world. You will get to see staff feed the bears but you will also get an opportunity to participate in building daily enrichment.

Sungai Hitam Boat Cruise

Cruise along the Sungai Hitam river for a chance to see highly endangered Proboscis monkeys, as well as several local villages.


We have chosen a special place for our yoga retreat. Located in the Borneo Orangutan Survival’s beautifully appointed eco-lodge where aesthetics and artisanal handicraft blend seamlessly into its breath-taking surroundings. You don’t have to even move from your bedroom with its panoramic views to enjoy the abundant wildlife all around.

Each twin room has its own en suite and exceptional views of the rainforest. For an extra fee, you can book a double bed kings room on the top floor of the lodge with an 180 degree view over the forest canopy, or a double bed queens room below that features an intimate 180 view of the forest understory. An unforgettable experience.

I loved walking through the forest, thevariety of plants, flowers, trees and animals. There was so much to discover. It was so peaceful and quiet – and still you could always hear different animal noises.

Petra Stuber

Thanks to the organizers of the program! What you and BOS achieve in general is unimaginable and to see it upclose is wonderful. I would also like to commend the staff at Samboja Lodge. Everyone is very friendly, motivated and seems very happy.

Mahakam River Adventure Tour

The Kalimantan Mahakam River is one of the greatest adventure tours of Indonesia, where the poison darts of the blow pipes still move their way through the rainforest!

Snorkel or take an optional scuba excursion to see schools of barracuda, whale sharks, green sea turtles, manta rays and more near Derawan’s coast.
