EXPEDITION TYPE:

Join us as we delve into some of Earth's oldest and most threatened forests, venturing deep into the Gunung Lesuer ecosystem of Northern Sumatra. This jungle is credited with being the last crucial stronghold for a plethora of critically endangered life, surviving alongside one another not unlike Earth before humans entered the global stage. Here, one is in the presence of sun bears, Sumatran tigers, Sumatran rhinos, Sumatran elephants and quite the list of wonderfully curious apes all in one place. Such pristine evergreen dipterocarp forest is shrinking every day thanks to illicit logging, unchecked palm oil cultivation and wildlife poachers. It is estimated that as much as 50% of this rainforest has been cleared in just the last 25 years. Such rampant destruction continues today at a truly incomprehensible rate.

Working with our local partners at Sumatra Eco Project, this adventure will take us first into the environments surrounding Bukit Lawang, then neighboring Tengulun, and critically- one of Sumatra’s last surviving coastal mangrove habitats, Karang Gading. We will target herps such as the king cobra, mangrove pit viper, red-headed krait, striped & blue coral snakes, reticulated pythons, wagler’s pit viper, and the Sumatran spitting cobra. Additional mammalian targets include the Sumatran elephant, Sumatran orangutan, sun bears, siamang gibbons, Thomas leaf nose monkeys, silver leaf langurs, Sunda pangolin, binturong, colugos, and slow loris. After the thrill of Sumatra, we’re adding an optional secondary adventure to Komodo National Park from Dec. 10-16. Keep scrolling for more info and a link to the Komodo-specific portion of this trip.

Our journey plays out over the course of 10 days, as we work our way through several habitats for their respective targets. Proceeds of this trip directly benefit the Sumatra Eco Project and its animal rehabilitation center. The center has successfully re-wilded nearly 500 displaced animals ranging from orangutans to serpent eagles and basically everything in-between.
