Cotapata National Park

Cotapata National Park (Parque Nacional y Área Natural de Manejo Integrado Cotapata) protects a dramatic slice of the eastern Andean slope in Bolivia's La Paz department, where the high, treeless puna spills down through misty cloud forest into the humid subtropical Yungas. Created in 1993 and covering roughly 600 km² only a short distance northeast of the city of La Paz, it packs an extraordinary altitudinal range into a small area — from glaciated peaks of the Cordillera Real above 5,000 m, down through high-Andean grasslands, wetlands and Polylepis (queñua) groves, into dense moss-hung cloud forest, and finally into warm montane rainforest around 1,300 m near Coroico. That gradient supports hundreds of vertebrate species and a very high diversity of plants.

For travellers, Cotapata is famous for one thing above all: the El Choro Trek, a classic multi-day descent that follows a pre-Hispanic, partly Inca-era stone-paved trade route from the pass of La Cumbre down to the village of Chairo. The walk is overwhelmingly downhill, losing well over 3,000 m of altitude as it crosses the entire park top to bottom. The park sits between La Paz and the resort town of Coroico, making it one of the most accessible wild areas in the country.

This is a place of weather extremes within a single trip — expect freezing wind and possibly snow at the start near La Cumbre, then heat, humidity, mud and mosquitoes by the time you reach Chairo. Bolivia's currency is the boliviano (Bs). Cash is essential; there are no ATMs or card facilities inside the park, and small community fees are collected in cash along the trail.

The park has no single "entrance" in the usual sense. Almost everyone enters at the top, at the La Cumbre pass on the La Paz–Coroico road, and exits at the bottom in Chairo. All access runs through La Paz.

By Plane

The nearest airport is El Alto International Airport (LPB), serving La Paz and sitting on the altiplano above the city at around 4,060 m — one of the highest international airports in the world. It handles domestic flights from across Bolivia plus regional international connections. From the airport, transfer down into La Paz (taxi or minibus, roughly 30–45 min depending on traffic) and arrange onward road transport to the La Cumbre trailhead from there. There is no airstrip in or beside the park itself.

By Train

There is no passenger rail service to Cotapata National Park or its trailheads. Bolivia's rail network is limited and primarily focused on freight, and remote natural areas like Cotapata are not served by rail. Travelers must rely on road transport (bus, shared taxi, or private vehicle) to reach the La Cumbre trailhead or other access points.

By Car / Road

From La Paz, head out on the old Coroico road toward the La Cumbre pass at roughly 4,650–4,700 m. The drive takes about 45 minutes to 1 hour by taxi; a private taxi from central La Paz to La Cumbre is the simplest option and lets you be walking by early morning. Minibuses and shared transport bound for Coroico also pass La Cumbre and can drop you at the trailhead — agree the drop-off point with the driver in advance, as the start of the Choro path leaves the highway at an apacheta (stone cairn) and downhill track.

At the bottom, the trek ends at Chairo, a small village in the lower Yungas. From Chairo there is no through public bus on a fixed schedule, so most hikers arrange (or share) a jeep/4x4 onward to Coroico (via Yolosa), typically a bumpy ride of around 1–2 hours on rough road. From Coroico there is frequent transport back up to La Paz. Because pickups at Chairo can be irregular, arranging the vehicle in advance, or teaming up with other trekkers to split the cost, saves a long wait.

Inside the park you get around almost entirely on foot. The El Choro is a single, well-trodden route, so navigation is straightforward, but it is a serious multi-day walk over uneven, often steep and slippery pre-Hispanic stone paving alternating with rougher, muddy forest track. There are no roads, taxis or public transport along the trail itself between La Cumbre and Chairo.

If you don't want to carry a full pack, porters and pack mules can be hired (most easily through La Paz tour operators, sometimes arranged with locals at the trailhead) to carry camping gear and food, letting you walk with a light daypack. Hiking poles help enormously on the relentless downhill. Pace yourself by the villages and camps along the way — Chucura, Challapampa and the small settlements lower down (toward Sandillani) are the natural staging points. For day visits, shorter walks are also possible from the Coroico/Yolosa side without committing to the full crossing.

• Andean páramo and puna near La Cumbre — wide, cold, treeless high country with views back to the snow peaks of the Cordillera Real, sometimes dusted with snow even in the dry season.
• Cloud forest (ceja de selva) in the middle stretch — dense, dripping, moss-hung montane forest alive with ferns, bromeliads, orchids and butterflies, often wrapped in mist.
• The pre-Hispanic stone-paved road itself — long sections of Inca-era and earlier paving, steps and retaining walls, one of the best-preserved old trade routes in the region.
• Waterfalls and river crossings — the trail repeatedly meets gushing streams and cascades, with footbridges and fords, as it drops into the warmer valleys.
• Casa Sandillani — the celebrated hillside garden created by Tamiji Hanamura, a Japanese gardener who settled here in the late 1950s and tended an immaculate garden by hand until his death in 2013. It remains a beloved, quirky landmark near the lower end of the trek.
• Wildlife — Cotapata lies within the range of the spectacled (Andean) bear (Tremarctos ornatus), and the park is exceptionally rich in birds, including the Andean cock-of-the-rock and, high up, the chance of an Andean condor. Sightings of large mammals are rare, but birdwatching is superb.

The reason almost everyone comes is the El Choro Trek — the classic 3-day (sometimes 4-day) crossing of the park.

• The route: La Cumbre → Chucura → Challapampa → Chairo (passing Casa Sandillani near the end), descending the whole way from roughly 4,700 m at the pass down to around 1,300–1,500 m at Chairo. Total walking distance is commonly cited at around 44–57 km, with the dramatic feature being the ~3,500 m of descent. A short initial climb to the high point is the only significant uphill; after that it is overwhelmingly downhill — easy on the lungs, hard on the knees.
• Day 1 typically crosses the high pass and begins the long drop through puna into the upper cloud forest, often camping around Challapampa.
• Days 2–3 continue down through ever-thicker, warmer forest, past small settlements, river crossings and Casa Sandillani, finishing at Chairo.
• Walking the old Inca/pre-Hispanic road: much of the joy is the engineering underfoot — stone paving, steps and drains built centuries ago.
• Birdwatching and nature: the changing ecosystems make for excellent birding and butterfly-spotting, especially in the mid-elevation cloud-forest belt; carry binoculars.
• Day hikes: not everyone does the full crossing — shorter walks from the Coroico/Yolosa side suit those who don't want the multi-day commitment, though the trek is designed as a one-way descent.

Guides, porters and mules are widely available through La Paz operators, and many independent hikers do the trail self-guided thanks to its clear, single route. Full guided tours from La Paz typically run a few hundred US dollars per person including guide, transport and gear (porters can be hired separately, on the order of US$35+ per day). Either way, community fees are collected at several points along the trail — for example small charges at Chucura and Challapampa and at other camps (typically Bs 10–25 per person/tent). Carry plenty of small boliviano notes. Allow 3 days minimum, and start as early as possible on Day 1 to clear the cold high section before afternoon weather closes in.

Plan to be self-sufficient — carry and cook your own food for the duration of the trek; there are no restaurants on the trail. Pack lightweight, high-energy meals (instant soups, pasta, oats, dried fruit, snacks) and a stove, since you cannot count on buying cooked food en route. Organised tours include a cook who prepares meals at camp. The small village shops stock snacks and drinks but not full meals, and supply is informal, so never depend on them. Proper eateries are only at the ends of the journey — in La Paz before you set off, and in Chairo and especially Coroico once you finish, where a hot meal is well earned.

Treat all water before drinking it. Streams and rivers are frequent along the route, but water should be boiled, filtered or chemically purified before use, as it is untreated. Carry enough capacity to cover the gaps between reliable water sources, especially on the hot lower sections. Small shops along the trail sell bottled water and soft drinks intermittently, but stock is limited and pricier than in town — don't depend on it. Bring electrolyte sachets for the lower, sweatier stretches. There is no bar or nightlife scene inside the park; that belongs to Coroico, where you can celebrate the finish.

Accommodation inside the park is basic and trail-bound — there are no hotels on the trail itself. Be realistic: the El Choro is a camping trek.

• Budget (camping / community lodging): the realistic option. Pitch a tent at simple community campsites in and around Chucura, Challapampa and other settlements (some toward Sandillani are covered riverside shelters). Several charge a small fee (commonly around Bs 18–25 per tent/person, varying by site), with rudimentary latrines and nearby water. Very basic rooms or hospedaje space sometimes exist in trail villages but cannot be relied upon.
• Mid-range: effectively unavailable inside the park. The nearest mid-range hotels and guesthouses are in Coroico, beyond the Chairo exit.
• Upscale / heritage: none inside the park. For comfortable or higher-end stays, base yourself in Coroico (hotels with pools and valley views) or in La Paz before and after the trek.

Carry a tent, a warm sleeping bag (the upper camps are cold) and a sleeping mat unless your tour provides them. Rates above are approximate and collected in cash.

There is essentially nothing to buy inside the park beyond basics. A handful of small village shops and family stalls along the trail (notably toward Sandillani) sell drinks, snacks, water, and sometimes cold beer or soft drinks at marked-up prices — handy, but stock varies and shouldn't be relied on for meals. Do all proper provisioning — trekking food, stove fuel, water-treatment tablets, batteries, sunscreen, insect repellent — in La Paz before you start, where supermarkets, outdoor shops and markets cover everything you need. Carry enough cash in small boliviano notes for community fees, shop purchases and the onward jeep from Chairo, as there is nowhere to withdraw money en route. Souvenirs and crafts are better found in La Paz or Coroico.

• Coroico (~1–2 hr by jeep from Chairo) — the warm, laid-back Yungas resort town that is the natural place to recover after the trek, with hotels, restaurants and valley views.
• La Paz (~45 min–1 hr to the La Cumbre trailhead; ~3–4 hr back from Coroico) — Bolivia's high-altitude hub for resupply, food and onward travel.
• Yungas Road / "Death Road" (near Coroico) — the notorious old cliffside road, now world-famous for the downhill mountain-bike descent from La Cumbre toward Coroico.
• Takesi Trek (also reached from near La Paz) — a comparable pre-Hispanic stone-paved Inca trail descending into the Yungas, the obvious next trek for those who loved El Choro.
• Sorata (~4 hr from La Paz) — a green valley town at the foot of the Illampu massif, a base for further Cordillera Real trekking and climbing.
