Madidi National Park is, by most scientific measures, the single most biodiverse protected area on Earth. Created in 1995, it spans nearly 19,000 km² of northwestern Bolivia and — almost uniquely among the world’s parks — packs nearly 6,000 vertical meters into that space, from steaming Amazon lowland up to snow-capped Andean peaks. That range is exactly why the numbers are so extreme: researchers have documented over 1,200 bird species (roughly 14% of every bird species on the planet), 200+ mammal species, nearly 300 fish species, and more than 120,000 insect species within a single park’s borders. This isn’t marketing language — it’s the conclusion of a multi-year scientific survey by the Wildlife Conservation Society, and it’s why serious wildlife travelers put Madidi on their list alongside the Galápagos or the Serengeti.

A Short History

Madidi was formally created as a national park and integrated natural management area in September 1995, protecting a landscape with both remarkable ecology and a deep human history — the region holds pre-Hispanic and colonial archaeological heritage alongside a living, present-day Indigenous population. In 2015, the Wildlife Conservation Society launched Identidad Madidi, a major multi-year scientific expedition that systematically surveyed the park’s biodiversity for the first time, ultimately adding more than 1,300 new species and subspecies records and identifying over 120 species that may be entirely new to science. That research is what put Madidi’s “most biodiverse park on Earth” claim on a solid scientific footing, rather than leaving it as an unverified tourism slogan.

What’s Actually Inside the Park

• The numbers, verified: Over 1,200 bird species, 270+ mammal species, nearly 500 fish species, 200+ amphibian species, and more than 120,000 documented insect species — figures compiled through WCS-led research in partnership with Bolivia’s national park service (SERNAP).
• Signature wildlife: Jaguars, Andean bears (Bolivia’s only bear species and one of the more elusive sightings in South America), giant otters, maned wolves, vicuñas, pink river dolphins, and harpy eagles all live within the park.
• 12 major ecosystems in one park: Because of its nearly 6,000m elevation range, Madidi contains everything from lowland Amazon rainforest and pristine savannah to cloud forest and high Andean puna — a range of habitats most parks can’t come close to matching.
• A living cultural landscape, not an empty wilderness: Madidi is home to 46 Indigenous communities across six ethnic groups, including the Tacana, Ese Ejja, Tsimané, and Mosetén, plus the Toromona, a group believed to remain in voluntary isolation. This is genuinely inhabited land, not an uninhabited nature reserve.

How People Visit Madidi

Independent access isn’t really possible — Madidi is visited almost exclusively through guided jungle tours departing from Rurrenabaque, in neighboring Beni department, which is Madidi’s standard gateway town despite the park itself sitting across the border in La Paz department. Nearly every trip starts the same way: by motorboat up the Beni River, which runs past Rurrenabaque; many lodges then continue onto the Tuichi River, a tributary that cuts deeper into the park itself.
Travel time varies far more than a single “multi-hour” figure suggests, since it depends entirely on which lodge you’re headed to:

• Closest option: San Miguel del Bala, just 40 minutes upstream on the Beni River alone — the most accessible lodge within the park.
• Mid-range: Most jungle ecolodges (e.g. Madidi Jungle Ecolodge), roughly 3 hours, continuing onto the Tuichi.
• Furthest/most immersive: Chalalán Ecolodge, 3.5–5.5 hours depending on water levels, reached via the Beni and then further up the Tuichi.

Several lodges, including community-run options like Chalalán (owned by the Indigenous community of San José de Uchupiamonas) and San Miguel del Bala, operate specifically to give visitors low-impact access while supporting the Indigenous communities who call the region home.

Best Time to Visit

• May–September (dry season): The recommended window — easier trekking, more comfortable conditions, and better wildlife visibility.
• October–April (rainy season): Lush and dramatic, but trails are muddier and access can be more difficult.

Safety

• A guide is essential, not optional. This isn’t a park with marked trails you can wander independently — dense, disorienting terrain and genuine cases of travelers going missing after leaving guided tours in this exact region (see our Rurrenabaque guide’s Safety section for the documented history) make this one of the clearest “stay with your guide” destinations in Bolivia.
• Remote medical access. Once inside the park, you’re genuinely far from medical care — reputable operators carry first aid and emergency protocols, which is part of why operator selection matters so much here.
• Standard Amazon lowland precautions apply — insect-borne illness risk, sun exposure, and the general lowland health guidance covered on our Beni guide.

Altitude Information

Not a single altitude to plan around — Madidi’s defining feature is its range, from Amazon lowland to nearly 6,000m Andean peaks within one park. Most tourist access (via Rurrenabaque) stays in the lowland Amazon zone, so altitude sickness isn’t a practical concern for the standard jungle tour experience. If your broader itinerary includes highland Bolivia, see our Altitude Sickness guide.

Good to Pack

See our full Rurrenabaque guide and Bolivia Packing List for jungle-specific packing detail — insect repellent, lightweight long sleeves, a headlamp, and binoculars are all essentials for a Madidi trip specifically.
