Did you know that Siberut Island National Park is home to 65% of Indonesia’s endemic mammal species, with four endangered primates found nowhere else on Earth? This UNESCO Biosphere Reserve, located in the Mentawai Islands off Sumatra’s west coast, offers one of the world’s last glimpses into an ancient way of life where indigenous traditions have remained largely unchanged for centuries.
Siberut Island National Park Overview
Covering approximately 1,905 square kilometers (735 square miles), Siberut National Park constitutes much of Siberut Island, the largest of the Mentawai Archipelago. Located about 150 km (93 miles) off Sumatra’s western coast, this pristine rainforest sanctuary was designated a UNESCO Biosphere Reserve to protect its exceptional biodiversity and cultural significance.
The park features diverse ecosystems including lowland rainforests, mangroves, peat swamps, and coastal areas. With elevations rarely exceeding 500 meters (1,640 feet), the terrain is crisscrossed by numerous rivers and streams that serve as natural highways through the dense jungle. Towering dipterocarp trees create a magnificent canopy that can reach up to 60 meters (197 feet) in height.
Beyond its natural wonders, Siberut is the ancestral homeland of the indigenous Mentawai people, who maintain traditional animistic beliefs and a sustainable way of life that has remained largely unchanged for centuries.

Getting Around Locally
Navigation within Siberut National Park requires local knowledge and often involves a combination of boat travel and jungle trekking:
River Travel
The island’s numerous rivers serve as natural highways. Dugout canoes and longboats are the primary means of transportation between coastal villages and interior settlements. Most guided tours include boat transfers as part of the package.
Jungle Trekking
Exploring the interior requires trekking through dense jungle on muddy trails. Paths can be challenging and often involve river crossings. A local guide is essential not only for navigation but also for cultural interpretation and wildlife spotting.
Local Guides
Hiring a Mentawai guide is mandatory for park exploration. Guides can be arranged through tour operators in Padang or at the park office in Muara Siberut. Choose experienced guides who speak your language and understand conservation principles.
Local Insight: The Mentawai people often travel barefoot through the jungle, which helps with grip on muddy surfaces. While visitors should wear appropriate footwear, be prepared for your shoes to get very muddy!
Where to Stay
Accommodation options in and around Siberut National Park are limited but provide authentic experiences:
Traditional Uma Homestays
For the most authentic experience, stay in a traditional Mentawai Uma (longhouse) with a local family. Accommodations are basic with sleeping mats on wooden floors, no electricity, and shared facilities. This immersive option provides unique cultural insights and typically includes meals prepared by your host family.
Eco-Lodges
A few eco-lodges operate on the fringes of the national park, offering slightly more comfortable accommodations while maintaining environmental sustainability. These typically feature private rooms with mosquito nets, shared bathrooms with basic facilities, and common areas for dining and relaxation.
Muara Siberut Guesthouses
In the port town of Muara Siberut, several simple guesthouses cater to travelers. While basic, they offer amenities like electricity, running water, and sometimes even Wi-Fi. These are good options for the night before or after your jungle trek.
“Staying in a traditional Uma longhouse was the highlight of my Siberut experience. Falling asleep to the sounds of the jungle and waking to the calls of gibbons created memories I’ll never forget.”
Dining & Local Cuisine
Food options in Siberut National Park reflect the island’s isolation and the Mentawai people’s traditional lifestyle:
Traditional Mentawai Cuisine
The Mentawai diet centers around locally sourced ingredients with minimal processing:
- Sago – The staple carbohydrate extracted from sago palm pith, often prepared as a porridge or baked into cakes
- Freshwater Fish – Caught from local rivers and typically grilled or boiled
- Wild Boar – Hunted sustainably and prepared for special occasions
- Taro and Sweet Potatoes – Cultivated in small gardens and prepared in various ways
- Bananas and Coconuts – Common fruits that supplement the diet

Dining Etiquette: When eating with Mentawai families, follow their lead. Food is often shared communally, and it’s polite to accept what’s offered. Eating is typically done with hands, so wash before meals (if water is available). Always thank your hosts for their hospitality.
What to Expect
Visitors should adjust their expectations regarding food variety and preparation methods. Meals in traditional villages are simple and repetitive, focusing on nutrition rather than culinary diversity. Tour operators typically bring supplementary food supplies for visitors, including rice, noodles, eggs, and canned goods.
In Muara Siberut, a few simple warung (small restaurants) serve Indonesian staples like nasi goreng (fried rice), mie goreng (fried noodles), and grilled fish. These provide more familiar options before and after jungle treks.
