Yoga in Borneo

Born in Madrid, growing up Rebeca heard of yoga philosophy from her grandmother – a practitioner and teacher in the 80s – but it was only years later while living in Sydney, Australia that she first started studying yoga at the Jivamukti School. Rebeca has been studying regularly with her teachers since and she feels forever grateful to our transformative method.

Rebeca’s teachings come now as a reflection of her dedicated daily practice and detailed observation of the natural world. She is devoted to protecting animal rights and teaching about yoga philosophy is her humble contribution towards all beings.

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.

Full Day Rainforest Trek

Less than one hour drive from Samboja Lestari lies a protected forest area for orangutans, sun bears, proboscis monkeys, 242 species of birds (9 species of hornbills!) and more! While trekking, see the rainforest from a different perspective by walking along the Canopy Bridge, 30 meters above the forest floor. A must-do activity!

Tree planting

There are more than 100,000 young trees of many varieties in our nearby plantation. Make your contribution to regenerating the forest for years to come by planting trees with our local staff.

Sungai Hitam Boat Cruise

Following a 30 minute drive from Samboja Lestari, you will take a leisurely boat ride along the Sungai Hitam river to see highly endangered proboscis monkeys and a river side village of houses built on stilts.

Canopy Bridge

See the rainforest from a different perspective by walking along the Canopy Bridge, 30 meters above the forest floor. A must-do activity!

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.

The sunbears were so cute, being surrounded by the rainforest as we’re so close is amazing, you can hear the orangutans which is really special. We’ll be back for sure, and we’re bringing the family.

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

5 days / 4 nights

The houseboat provides lodging and full-board meals for several days during your trip, giving you a unique experience of living on a river. Several highlights of the tour include traditional villages, dance performance, wildlife, jungle trekking, museum and a Royal Palace.

Trekking in Kutai National Park

3 days / 2 nights
Kutai National Park in East Kalimantan has been established to protect a wild population of around 2000 wild orangutans and other species, as well as traditional Bugis Dayak villages.
We will go deep into the Bornean rainforest in search of endangered fauna and flora, staying overnight in the Camp Kakap. Perhaps one of the most exciting experiences is a night rainforest trek when the cacophony of sound is quite overwhelming!

Derawan Archipelago

Welcome to paradise! The classic tropical islands of the Derawan Archipelago are where you go to trade jungle trekking and orangutans for white unspoiled beaches, palm trees and warm blue sea. 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.

Komodo and Rinca

Visit the Komodo dragon feeding grounds, swim in a beautiful coral garden, or simply relax by the ocean, and prepare to have your breath taken away by such unforgettable locations as Batu Cermin cave, the Rinca & Komodo Islands, and the famous Pink beach! During your time you will have the chance of witnissing animals include the water buffalo, monkeys and, of course, the famous Komodo dragon.
