Noel Kempff Mercado National Park: Bolivia's Remote Wilderness

Noel Kempff Mercado National Park protects 1,523,446 hectares of Amazon rainforest, Cerrado savanna and sandstone tableland along Bolivia's border with Brazil — an area larger than Connecticut and home to fewer than 1,500 visitors a year. Reaching it takes a charter flight or a two-day 4x4 and river journey from Santa Cruz de la Sierra, and that difficulty is precisely what keeps its jaguar, tapir and giant otter populations intact.

The park was founded in 1979 as Huanchaca National Park and renamed in 1988 for Noel Kempff Mercado, the Bolivian biologist who campaigned for its protection before his murder in 1986. UNESCO inscribed it in 2000 under natural criteria (ix) and (x), citing an unbroken record of evolutionary processes and an exceptional range of habitats.

What Makes This Park Different

Most Amazon parks are flat and green. This one has a 200-meter sandstone cliff running through it.

The Huanchaca Plateau

The park's defining feature is the Serranía de Huanchaca, a Precambrian sandstone tabletop that rises abruptly from surrounding lowland forest to roughly 1,000 meters. Its summit holds open grassy savanna, rock outcrops and stunted woodland that feel nothing like the jungle below — a relic landscape isolated long enough that scientists still study its plant communities for clues about past climate shifts. Standing at the rim, you look over a green ceiling that stretches to the Brazilian border.

Geologically, the plateau records more than a billion years of Earth history, from Precambrian sediments through Cambrian layers. That deep timeline is a large part of why the World Heritage listing went through.

Waterfalls Along the Rim

Water drains off the plateau in a series of falls. Arco Iris (Rainbow) is the most photographed, a curtain of water roughly 80 meters high that throws spray rainbows in morning light. El Encanto drops about 60 meters into a forested canyon, with natural pools above and below the drop where you can swim. Federico Ahlfeld is a third set, less visited and often quieter.

Access to the falls depends entirely on which sector you enter. From the northern Flor de Oro base, Arco Iris and El Encanto are reachable on day hikes. The southern Los Fierros sector gives you savanna and forest walks but puts the falls several hours away.

Five Ecosystems in One Border

Because the park spans 200 to 1,000 meters in elevation and sits where Amazon forest meets dry Cerrado, it packs in habitats that normally require separate trips. Botanists count more than 4,000 plant species, with evergreen rainforest on deep soils, semi-deciduous forest, gallery forest along rivers, wetland, and what may be the largest remaining block of undisturbed Cerrado in the world. Around 620 bird species and 139 mammal species have been recorded, including jaguar, lowland tapir, giant river otter and black-tailed silvery marmoset.

The Cerrado here burns naturally from lightning strikes most years, and the vegetation has adapted to it. If you visit late in the dry season, expect blackened ground in the open savanna — it is part of the system, not damage.

Planning Your Visit

This is not a park where you buy a ticket at a gate. Entry requires prior authorization from SERNAP, Bolivia's protected areas service, and in practice that means booking through an authorized operator in Santa Cruz.

Getting There

All trips start in Santa Cruz de la Sierra, whose Viru Viru International Airport receives flights from Lima, São Paulo and Madrid among others. From there you have two routes.

The fast option is a light charter aircraft, roughly two hours to the Flor de Oro airstrip in the north, or to the El Refugio research station on the Paraguá River at the park's edge. The slow option is road plus river: about 340 kilometers of driving over 8 to 9 hours to the settlement of Piso Firme, then a boat down the Paraguá toward the Iténez. The overland route adds days but shows you the working eastern lowlands — cattle country, small river towns, and a road that simply stops at the water.

Do not plan on arriving independently. There is no public transport into the park and no accommodation outside the operator-run camps.

When to Go

The dry season runs roughly May through October, and that is the only reliable window. Rivers are low enough to navigate, airstrips are usable, and trails hold up. Rainfall from November to March can make access effectively impossible, and even in season light aircraft get grounded by weather for a day or two at a time. Build slack into your itinerary.

Temperatures average 25 to 26°C year-round, but between June and August cold Patagonian air can push nighttime lows toward 10°C for several days. Bring a fleece. The mosquitoes are relentless regardless of season, and repellent with high DEET content is not optional.

Costs and Permits

Park entry runs about 100 bolivianos (roughly US$14.50) for foreign visitors and 30 bolivianos for Bolivian nationals and residents, though rates change — confirm with your operator or SERNAP before you travel. Multi-day expedition packages from Santa Cruz typically start around US$1,500 per person and include flights, food, camping equipment and guides. Group size matters: operators divide fuel and charter costs across the party, so a group of six pays noticeably less per head than a group of two.

Allow five to eight days for the trip. Shorter four-night itineraries focus on the northern falls; longer ones add the plateau and river sections.

Practical Advice From Experience

The single most common mistake is treating this like a normal national park visit. It is an expedition with fixed logistics, and a missed charter connection can cost you two days.

Fly in rather than drive if your schedule is tight. The 4x4 route is genuinely interesting, but road conditions in the wet-dry transition can add half a day without warning, and there is no plan B if a bridge is out.

Ask your operator which sector they actually use. Many standard tours go north to Flor de Oro because the falls are close and the airstrip is reliable. The southern Los Fierros entrance, reached from San Ignacio de Velasco, offers better savanna wildlife viewing but longer transfers to the waterfalls. If waterfalls are your priority, say so before booking.

Take the plateau walk if you can handle heat and full sun. The summit is exposed, with little shade and rocky footing, but the views and the odd dwarf vegetation are what separates this park from every other Amazon destination. Guides from the local communities know the routes and the wildlife, and hiring them is both required and worthwhile.

Carry more water than feels reasonable and treat any cut or blister immediately. Medical facilities are hours away by air.

Frequently Asked Questions

Can I visit Noel Kempff Mercado without a tour operator?

No. SERNAP requires advance authorization for all visitors, and there is no public transport, no gas station, no food supply and no lodge outside operator-run camps. Independent travelers who arrive at San Ignacio de Velasco or Piso Firme without arrangements are usually turned back.

How much does a trip to the park cost?

Expect a minimum of around US$1,500 per person for a five-day expedition from Santa Cruz, covering charter flights, permits, meals and camping. Park entry itself is only about 100 bolivianos, so logistics rather than fees drive the budget. Larger groups lower the per-person charter cost significantly.

What is the best month to see the waterfalls?

July and August sit in the heart of the dry season, when airstrips and trails are most reliable, but water volume is lower. June and September offer a reasonable balance of access and flow. Avoid December through March entirely; heavy rain can strand flights and close routes.

How fit do I need to be?

Moderate fitness is enough for the standard waterfall walks, which involve a few hours of humid forest hiking with some slippery sections. The Huanchaca Plateau traverse is harder — exposed, rocky and hot — and is best for travelers comfortable with six or more hours on their feet.

Is there malaria or yellow fever risk?

Yellow fever vaccination is recommended for this part of lowland Bolivia and is often required for onward travel; consult a travel clinic at least a month before departure. Malaria prophylaxis is generally advised for the Santa Cruz department lowlands. Bring antimalarial medication and insect repellent rather than relying on local supplies.
