Indonesia
Granite megaliths shaped like human faces staring blankly across misty valleys of the Wallace Line.
The stone faces stare up from the valley floor. Some are two metres tall, carved from granite into expressions that range from serene to anguished. No one knows who made them, or when, or why. The best estimate is 1,000-5,000 years old, but the Bada Valley megaliths remain genuinely unexplained — no inscriptions, no archaeological consensus, no cultural memory among the local Behoa people. The park surrounding them straddles the Wallace Line, where Asian and Australian fauna collide. Anoa (dwarf buffalo) share the forest with maleo birds that incubate eggs in volcanically heated ground.
Lore Lindu National Park covers 2,290 square kilometres of montane forest in Central Sulawesi, straddling the Bada, Napu, and Besoa valleys. The park protects over 200 megalithic stone sculptures — primarily in the Bada Valley — depicting human figures, animals, and abstract forms. The megaliths remain undated with certainty, with estimates ranging from 1,000 to 5,000 years old. No definitive cultural link has been established to any known civilisation, making them among Southeast Asia's great archaeological mysteries. Ecologically, Lore Lindu sits on the Wallace Line and supports endemic species including the Sulawesi anoa, babirusa (pig-deer), Sulawesi warty pig, and the maleo bird (which uses geothermal heat for egg incubation). Trekking routes connect the three valleys through dense montane forest. Access is from Palu (3-hour drive to the park boundary). Accommodation is basic — village homestays in Bada or Wuasa.
Solo
Trekking between valleys of unexplained megaliths in Wallace Line jungle — this is deep solo exploration where genuine mystery still hangs over the landscape.
Friends
Multi-day treks through the valleys, debating megalith theories around campfires, and spotting Wallace Line endemics together makes Lore Lindu a thinking person's group adventure.
