To step into the Siberut rainforest is to step outside modern time. The Mentawai people believe every leaf, river, animal, and stone possesses an immortal soul (simagere) that must be honored in balance.

The Archipelago and the Flower Men

The Mentawai archipelago consists of four primary islands off the western coast of Sumatra: Siberut, Sipora, North Pagai, and South Pagai. While modern development has touched the outer islands, the dense, roadless interior of Siberut remains one of the world's last sanctuaries of undisturbed indigenous culture.

Here live the Mentawai Tribe — known affectionately as the Flower Men for their practice of adorning their hair and bodies with fresh jungle blooms, medicinal herbs, and hand-woven rattan beads. Having lived in isolation for thousands of years, their animistic belief system (Arat Sabulungan) maintains total equilibrium between humanity and the spirits of the rainforest.

Living in the Uma Longhouse

Mentawai community life revolves around the Uma — a communal timber longhouse elevated on hardwood stilts. Constructed entirely without nails, these sprawling open-air dwellings serve as clan homes, meeting grounds, and ritual shrines lined with ceremonial wood carvings and ancestral totems.

The Wisdom of the Sikerei (Shamans)

At the spiritual core of every clan is the Sikerei — the tribal shaman, medicine healer, and keeper of oral history. The Sikerei possess an encyclopedic knowledge of thousands of rainforest plants, utilizing botanical roots, leaves, and resins for natural medicine and ceremonial purification.

Self-Sufficiency and Sago Harvesting

The Mentawai maintain complete food independence from the outside world. Their staple diet centers around the starch extracted from wild sago palms, complemented by river fish, foraged jungle greens, and forest cultivation.
