Represa Toro Wanuna is a small, concrete‑gravity structure built to regulate water flow in the high‑Andean watershed that feeds the surrounding valleys. Its modest height belies its importance: at 4,000 m the dam helps sustain irrigation, livestock watering, and local community needs in an environment where water can be scarce and seasonal.
A Brief History
Official records list the dam under the code MMAyA CB‑P‑099, indicating it is part of the Ministry of Environment and Water’s (Ministerio del Medio Ambiente y Agua) network of water‑resource projects. While detailed historical narratives are scarce, the dam’s existence reflects Bolivia’s long‑standing effort to harness Andean water sources for agriculture and rural development. Its construction likely dates to the late 20th or early 21st century, a period when the Bolivian government intensified infrastructure projects in the Cochabamba department.
Why It Matters
- Water Security: In high‑altitude zones, even a small reservoir can make the difference between a thriving community and a water‑shortage crisis.
- Ecological Balance: By moderating river flow, the dam supports downstream ecosystems and prevents sudden floods during the rainy season.
- Cultural Landscape: The dam sits amid traditional Quechua and Aymara farming terraces, offering a living example of how modern engineering coexists with age‑old agricultural practices.
How to Get There
By Air
The nearest major airport is Jorge Wilstermann International Airport (CBB) in Santa Cruz de la Sierra, about 140 km (87 mi) east of Colomi. From the airport, you can rent a 4×4 vehicle or arrange a private transfer to Cochabamba city (≈ 340 km north) and then continue to Colomi.
By Bus
Cochabamba’s central bus terminal hosts daily services to Colomi. The journey takes roughly 4–5 hours on a standard inter‑city bus, winding through scenic valleys and high‑plain vistas. Ask the driver to drop you off at the Colomi municipal office—most locals will point you toward the road that leads to the dam.
By Car
If you prefer driving, follow these steps:
- From Cochabamba: Take Route 4 (Ruta 4) heading north toward Tiquipaya.
- Turn onto Route 7: After Tiquipaya, follow signs for Colomi (approximately 120 km).
- Local Road: Once you reach Colomi, ask for directions to “Represa Toro Wanuna”. The dam sits just a few kilometers outside the town, accessible via a gravel road that is well‑marked but may be rough after heavy rain—bring a high‑clearance vehicle.

Best Time to Visit
| Season | Weather | Visitor Experience |
|---|---|---|
| Dry Season (May – October) | Clear skies, cool days, cold nights; minimal rain. | Ideal for photography, hiking, and stable road conditions. |
| Rainy Season (November – April) | Frequent afternoon showers, occasional fog. | Water levels rise, offering a fuller reservoir view, but roads can become muddy. |
Recommendation: Aim for June to September. The dry, sunny days provide excellent visibility of the surrounding Andes, and the high altitude means crisp air perfect for trekking. If you’re interested in seeing the dam at higher water capacity, a late‑January visit during the rainy season can be rewarding—just prepare for possible road delays.
What to Expect
The Landscape
Approaching Represa Toro Wanuna, you’ll first notice the stark contrast between the white‑washed concrete of the dam and the deep green of native tussock grasses that cling to the slopes. The reservoir, though modest, reflects the sky in a brilliant turquoise hue, framed by distant snow‑capped peaks that punctuate the horizon.
The Atmosphere
At 4,000 m, the air is thin, and you may feel a slight shortness of breath until you acclimatize—take it easy, hydrate, and avoid strenuous activity for the first hour. The silence is profound; the only sounds are the gentle lapping of water against the dam and occasional distant bird calls.
Photographic Opportunities

Travel Tips
- Acclimatize Properly – Spend at least a night in Cochabamba (2,500 m) before heading up to 4,000 m.
- Dress in Layers – Temperatures can swing from 15 °C (59 °F) in daylight to below 0 °C (32 °F) after sunset.
