Oldest Eco-Tourism Spot in Lombok: Otak Kokok Waterfall

You would not know that, Lombok has the olderst eco tourism spot, so, let me tell you about Otak Kokok. Otak Kokok Waterfall and Joben Eco Park are tucked away in the quiet village of Montong Betok, East Lombok. What make it special is, this area is already under the gentle care of Joben Resort, part of the Mount Rinjani National Park Authority.

The heart of this place is a waterfall that flows straight from the ancient roots of a banjúr tree—said to be hundreds of years old. It’s a rare and sacred sight, where nature seems to speak in its own still language.

The name Otak Kokok, in the Sasak language, means “water source” or “river head”—a name as humble as it is meaningful. According to local belief, this waterfall holds healing powers. It’s said that if you bathe beneath it and the water turns milky white as it touches your skin, it reveals the presence of illness in your body. And if you continue to let the water wash over you, the illness may slowly lift and leave.

To bathe under water that flows straight from the base of a living, centuries-old tree is to feel something otherworldly. The sensation is extraordinary—the water stays icy cold, even under the sun’s heat. And the view? It soothes the eyes and calms the spirit.

Unlike most waterfalls that demand a long trek and a descent of countless stairs, Otak Kokok welcomes visitors with ease. Just 30 steps down, and you’re there—standing before its fresh, flowing grace.


It’s not just the waterfall that holds wonder. The bathing pool at Otak Kokok Joben, too, is said to carry healing gifts. The water here springs directly from the foothills of Mount Rinjani, and for generations, the people of Pesanggrahan Village have believed it holds the power to cure all kinds of ailments.

In addition to the waterfall itself, the site also offers two large swimming pools—equally cool and refreshing. For those who may feel unsure about bathing directly beneath the falls, these pools offer a gentler alternative to enjoy the same mountain waters.

In a time when many natural sites are struggling to compete with flashy, man-made attractions promising ‘perfect’ vacations, Otak Kokok Waterfall and Joben Resort still hold strong. The pull of tradition and the growing desire to return to the calm of nature continue to make this place a favorite among locals and curious travelers alike.
