Represa de Reque en Cayara – The Hidden High‑Altitude Dam of PotosĂ, Bolivia
Discover the quiet power of the Andes at a dam perched nearly 4,000 m above sea level. Whether you’re a road‑trip enthusiast, a photography lover, or a cultural explorer, Represa de Reque en Cayara offers a unique slice of Bolivian landscape that’s still off the typical tourist radar.
1. Introduction
Imagine a crystal‑clear reservoir glimmering against a backdrop of snow‑capped peaks, the air thin enough to taste the earth, and the only sound being the gentle rush of water over a modest 18‑metre high concrete wall. That’s Represa de Reque en Cayara, a small but striking dam tucked into the high Andes of PotosĂ, Bolivia.
Most travelers to Bolivia head straight for Salar de Uyuni, La Paz, or the historic mining city of PotosĂ. Yet the region surrounding the capital holds a network of hidden gems—waterfalls, natural springs, and remote dams—that showcase the country’s rugged beauty and its centuries‑old relationship with water management. Represa de Reque en Cayara is the perfect base‑camp for those seeking solitude, breathtaking altitude scenery, and a glimpse into the engineering that sustains local communities.
2. About Represa de Reque en Cayara
- Type: Dam (🏗️)
- Location: Cayara, PotosĂ Department, Bolivia
- Coordinates: -19.577807, -65.959105
- Height: 18 m
- Altitude: 3,985 m above sea level
The dam sits in the small settlement of Cayara, a stone’s throw from the main road that links the city of Potosà with the high‑plain communities of the Altiplano. While there is no dedicated Wikipedia entry, local records indicate that Represa de Reque was constructed in the latter half of the 20th century to regulate water flow for irrigation and livestock in an otherwise arid valley. Its modest height belies its importance: at nearly 4 km above sea level, the reservoir captures melt‑water from surrounding glaciers and seasonal rain, providing a reliable water source during the dry season.
From a cultural perspective, the dam is a reminder of Bolivia’s long tradition of communal water projects, dating back to pre‑Inca societies that built terraces and canals in the Andes. Today, Represa de Reque continues to serve nearby farms, and its tranquil reservoir has become an informal gathering spot for locals who come to fish, wash clothes, or simply enjoy the panoramic view.
3. How to Get There
By Air
The nearest major airport is Jorge Wilstermann International Airport (CBB) in Cochabamba, about 250 km north‑west of PotosĂ. From there, catch a domestic flight to Juan Mendoza Airport (POI) in PotosĂ (approximately a 45‑minute flight).
By Bus or Car from PotosĂ City
PotosĂ’s historic center sits at roughly 4,090 m altitude, only 30 km east of Cayara. The most straightforward route is:
- From the city center, head west on Ruta 1 (the main highway toward Sucre).
- After passing the town of Tarapaya, look for the signposted turn toward Cayara. The road narrows into a paved but winding mountain stretch.
- Travel time: 45 – 60 minutes by car or 1 ½ hours by local bus (buses leave the main terminal every 2‑3 hours).
Public Transport Tips
- Bus tickets can be purchased at the Terminal de Buses de PotosĂ. Ask the driver for “Cayara” or “Represa de Reque” to ensure you’re on the right line.
- Shared taxis (collectivos) are also common; they usually depart when the vehicle is full, so be flexible with timing.
- Renting a 4Ă—4 is advisable if you plan to explore nearby attractions on foot, as some access roads become gravelly after rain.
What to Pack
- Altitude‑ready clothing (layers, windproof jacket) – temperatures can swing from sunny 20 °C to below freezing at night.
- Sun protection – the high UV index at 4,000 m is intense.
- Water and snacks – services are sparse near the dam.
4. Best Time to Visit
| Season | Weather | Visitor Experience |
|---|---|---|
| Dry Season (May – October) | Clear skies, low humidity, cooler nights | Ideal for photography, stargazing, and hiking. Water levels are stable but lower, revealing more of the dam’s structure. |
| Rainy Season (November – April) | Occasional showers, higher river flow | The reservoir swells, creating dramatic reflections. Some access roads may be muddy, so a 4×4 is recommended. |
Peak recommendation: Late September and early October. The sky is exceptionally blue, the temperature is mild, and the surrounding valleys are still lush from the brief summer rains.
5. What to Expect
Arriving at Represa de Reque en Cayara feels like stepping into a living postcard. The dam’s concrete wall rises 18 m above the water, but it’s the surrounding landscape that steals the show:
- Panoramic vistas: On a clear day, you can see the snow‑capped peaks of the Cordillera de los Andes stretching toward the horizon. The reservoir mirrors these mountains, creating a perfect symmetry for landscape photographers.
- Quiet ambience: Unlike popular tourist sites, the dam is rarely crowded. You’ll hear the soft splash of water, occasional livestock, and the distant call of Andean condors.
- Local life: Small groups of shepherds often gather to water their llamas. If you’re lucky, a local family may invite you to share a cup of mate de coca, a traditional high‑altitude tea.
- Hiking opportunities: A short, unmarked trail leads from the dam’s edge to a viewpoint 200 m higher, offering a sweeping outlook over the valley. The trail is moderate—suitable for hikers with basic altitude acclimatization.
Because the dam sits at 3,985 m, you may feel the effects of altitude (lightheadedness or shortness of breath). Take it easy, stay hydrated, and consider spending a night in Potosà first to acclimatize.

7. Travel Tips
- Acclimatize Properly – Spend at least one night in Potosà (4,090 m) before heading to the dam to reduce altitude sickness.
- Bring Cash – Small villages around Cayara rarely accept cards; Bolivianos (BOB) are needed for food or transport.
- Stay Connected – Mobile coverage is spotty. Purchase a local SIM (Entel or Tigo) in Potosà for emergency contact.
- Respect Local Customs – Ask permission before photographing people, especially when they are working or tending livestock.
- Pack Light, Pack Smart – A sturdy pair of hiking boots, a windproof jacket, and a reusable water bottle are essential.
- Leave No Trace – The area is pristine; carry out all trash and avoid disturbing the natural spring sources.
- Check Road Conditions – During the rainy season, the unpaved sections near the dam can become slippery. Call a local taxi service the night before to confirm accessibility.
