- Primary lowland rainforest interior — Ancient dipterocarp trees, thick understory and a layered canopy make the heart of Siberut feel properly primeval. Hikes here are sweaty, muddy and worth it: you’re walking through one of Indonesia’s most intact lowland rainforests, with mossy buttress roots and a real sense of solitude.
- Kloss’s gibbon mornings — This endemic gibbon’s eerie, rising-and-falling duet is the sound of Siberut; hearing it echo through the trees is unforgettable. They’re strictly arboreal and tricky to see, so mornings spent listening and glassing the canopy are your best bet — absolutely my personal favorite.
- Mentawai macaques & other endemic primates — The island’s primate lineup (Mentawai macaque among them) is unusually island-specific, so encounters feel special — cheeky

- Mentawai macaques & other endemic primates — The island’s primate lineup (Mentawai macaque among them) is unusually island-specific, so encounters feel special — cheeky macaques on the forest edge, shy langurs higher in the trees. You’ll notice different behaviours than on the Sumatran mainland; bring binoculars and patience.
- River journeys and mangrove corridors — Traveling by longboat down the park’s rivers opens areas you can’t reach on foot: winding mangroves, birdlife-rich riverbanks and quiet pools where wildlife comes to drink. Boat trips are a practical, low-effort way to spot kingfishers, monitor lizards and other riverine species.
- Traditional Mentawai villages (uma longhouses) — Scattered near the park edges, the raised uma longhouses and their cultural landscape add a human dimension that’s tightly linked to the forest. Visiting (with consent) shows traditional forest use — sago gardens, hunting techniques and tattoo artistry — and helps you understand why conserving the forest matters.
- Waterfalls and freshwater pools — Short jungle scrambles often end at small cascades and clear plunge pools that feel wildly remote; great for a cooling swim after a humid trek. They’re not “tourist waterfall” spectacles, but that’s the point — quiet, green, perfect for a midday break.
- Secluded beaches fringed by jungle — The coastline alternates between rocky headlands and long, empty beaches backed by tropical forest — nice for camping or a relaxed day after inland hiking. Expect basic facilities; these are more about peace and scenery than resorts.
