From wikipedia:

The people of Trunyan practice customs found nowhere else in Bali, many even unique among the Bali Aga people. Among the unique customs of the Trunyanese is their treatment of dead bodies. Instead of cremations, the funeral rite of dead bodies in Trunyanese society is for them to be simply laid on the ground, covered by cloth and a bamboo cage, and left to decompose. The influence of an ancient banyan tree (known as taru menyan, literally "nice smelling tree") near the burial ground is thought to keep the corpses from smelling putrid. It is said that the tree emits a scent which neutralizes the smell of rotting bodies. It is also said that from this tree the name trunyan is derived. When a corpse has fully decomposed, the skull is placed on a stair-shaped stone altar which is located 500 meters north of the banjar Kuban, a special place which can only be reached by boat. Only the bodies of married couples are allowed to be treated like this. If the deceased is not married, the body is buried at a cemetery.^[1]

These Trunyanese funeral rites date back to the neolithic Agama Bayu sect, one of the six most important religious-spiritual sects during pre-Hindu period in Bali.

One day our host Putu organized for us a trip to this place next to lake batur.
