Backpacking in Potrerillos
👌 Worth visitingvillage ranked #4
By Johan Kruseman 🇳🇱 | Updated October 19, 2026

People assume Potrerillos is just a dam and a reservoir you glimpse from a bus window on the way to Chile. It's actually a proper village, tucked in the Andean foothills of Mendoza province, about an hour west of Mendoza city. For backpackers, it's a mixed bag in the honest sense: no hostels lining a main strip, no nightlife, but genuinely dark skies, river sound at night, and access to hikes that don't require a guide company markup. Evenings are quiet, communal dinners at guesthouses, early to bed. You'll meet other travelers if you're staying somewhere social, but it's smaller-scale than Mendoza city or even Uspallata. I remember sitting by the reservoir at dusk, wind dropping suddenly, watching the water turn the color of the surrounding rock, and realizing I hadn't heard a car engine in twenty minutes. That silence is the whole pitch.

✨ Why go?
Ranked #4 village in Argentina
What sets this place apart

Backpackers stop in Potrerillos mostly as a breather between Mendoza's wine-and-hostel circuit and the rougher, higher-altitude stretches toward Uspallata or the Chilean border. The village works as a slow-travel pause: no major sights to rush toward, just river access, short-to-moderate hiking trails, and a reservoir used for kayaking and windsurfing in warmer months. It suits hikers, couples wanting a quiet night away from dorm noise, and solo travelers who don't mind a low-key evening. It's not a party stop, and most people stay one or two nights rather than lingering a week. The atmosphere leans calm and residential rather than touristic, so don't expect a packed hostel common room every night, though a few guesthouses do attract a steady trickle of travelers heading the Mendoza-to-Santiago … read more 👉

The atmosphere leans calm and residential rather than touristic, so don't expect a packed hostel common room every night, though a few guesthouses do attract a steady trickle of travelers heading the Mendoza-to-Santiago route. If you need constant stimulation, this isn't your spot. If you want a genuine pause with mountain air and unhurried mornings, it delivers exactly that.

💡 HighlightsThe experiences that define the visit

  1. Embalse Potrerillos (the reservoir): The centerpiece of the village, this turquoise-green reservoir is surrounded by dry Andean hills and offers kayaking, stand-up paddleboarding, and windsurfing rentals from small operators near the shore. Best visited in summer (December to February) for water activities, or early morning in any season for photography. Renting a kayak typically costs a modest hourly fee, and a paddle session runs about one to two hours.
  2. Cerro Cocodrilo viewpoint hike: An easy trail near the dam climbing to a wide panorama over the reservoir and surrounding peaks. It takes roughly 1.5 to 2 hours round trip and costs nothing beyond good shoes and water. Go in the cooler morning hours, especially in autumn or spring, to avoid midday sun.
Beyond the village itself, Cacheuta hot … read more 👉

Beyond the village itself, Cacheuta hot springs and the Uspallata valley make excellent day trips, both reachable within an hour or so; Cacheuta, with its riverside thermal pools, is my personal favorite for an afternoon of doing absolutely nothing productive.

🌤️ When to go?Seasonal considerations and timing

  • Summer (December to February): Warm days around 28-32°C (82-90°F), good for reservoir activities like kayaking and windsurfing, but also peak domestic tourism from Mendoza city, so weekends get busier and prices rise slightly.
  • Autumn (March to May): Mild days near 18-22°C (64-72°F), clear skies, fewer visitors, ideal for hiking without heat exhaustion.
  • Winter (June to August): Cold, often 5-12°C (41-54°F) during the day and near freezing at night, quiet season with lower guesthouse rates, but some trails and water activities shut down.
  • Spring (September to November): Comfortable 15-20°C (59-68°F), wildflowers along the trails, moderate crowds, good daylight hours for full-day hikes.
Aim for a weekday in autumn, when the reservoir viewpoints are often empty, unlike on a summer Saturday.

🛏️ Where to stay?Best areas and accommodation options

Guesthouses (hospedajes) and small cabañas dominate the lodging scene here rather than traditional hostels, so budget travelers should look for shared cabañas or rooms in family-run properties near the reservoir road, which tend to run cheaper and often include breakfast. A few properties cater specifically to backpackers and cyclists passing through on the Mendoza-to-Chile route, offering dorm-style rooms or shared kitchens.

Guesthouses (hospedajes) and small cabañas dominate the lodging scene here rather than traditional hostels, so budget travelers should look for shared cabañas or rooms in family-run properties near the reservoir road, which tend to run cheaper and often include breakfast. A few properties cater specifically to backpackers and cyclists passing through on the Mendoza-to-Chile route, offering dorm-style rooms or shared kitchens. Camping is also viable in designated areas near the reservoir during warmer months, and it's the cheapest option by far if you have your own gear. Because the village is small, availability can be tight during summer weekends and Argentine holiday periods, so booking a day or two ahead helps. Staying closer to the reservoir puts you near kayak rentals and the main viewpoint trail, while accommodations slightly further up the valley offer quieter nights and better stargazing. Don't expect late check-in flexibility everywhere; many hosts are small-scale and keep early hours, so confirm arrival times in advance, especially if you're coming in on a late bus from Mendoza city.

🚌 Day tripsExploring the surroundings

Potrerillos works well as a base for day trips because Ruta 7 runs straight through the valley, and buses between Mendoza and the Chilean border stop on the highway, so most outings take 30 minutes to 2 hours each way.
Cacheuta Hot Springs:
The thermal pools sit about 20 km east along the Mendoza river, in a canyon with steaming water and cold air at the edges. Allow a half day. Local buses toward Mendoza drop you at the Cacheuta turnoff for roughly US$1 to 2, and day entry to the thermal complexes runs about US$25 to 45. Visit from May to September, when soaking in cold air feels best. First-timers often arrive without a swimsuit and towel, and renting them adds up.

Visit from May to September, when soaking in cold air feels best. First-timers often arrive without a swimsuit and towel, and renting them adds up.

Uspallata Valley:
Head west for about 1.5 hours on Ruta 7 to reach a wide, dry valley ringed by multicolored hills, the setting of film scenes and old Inca trail traces. Buses toward Chile pass the area, and a round trip costs around US$8 to 14. The shoulder months of October to November and March to April give clear skies without the summer heat. Many people stay too short; plan at least three hours on the ground, because the last bus back leaves earlier than expected.

Puente del Inca:
A natural rock bridge stained orange and yellow by mineral springs spans the river at 2,720 m, with the ruins of an old spa hotel beside it. The ride takes about 2.5 to 3 hours each way, so start early. Expect US$12 to 20 return on a regular bus, plus a few dollars for snacks. December to March is the safest window, since snow can close the pass in winter. The common error is skipping layers; the wind at this altitude is sharp even in January.

Mendoza City and Wineries:
The city lies about 50 km east, around 1 to 1.5 hours by bus, and gives you wine tastings in Luján de Cuyo plus a walkable center of plazas. A bus return is about US$3 to 5, bikes rent for roughly US$10 to 15, and a tasting costs US$8 to 25. Harvest season, February to April, is liveliest. Book wineries in advance, because many refuse walk-ins.

FAQTraveler FAQ

Potrerillos is reached most easily from Mendoza city, about an hour away by regular bus service or remise (private car), with buses running multiple times daily from Mendoza's main terminal. There's no train service, and most backpackers combine the trip with onward travel toward Uspallata or the Chilean border. A one-way bus ticket typically costs only a few hundred Argentine pesos.
It's worth it if you want a quiet, scenic pause with hiking and reservoir access rather than sightseeing-dense days. It won't satisfy travelers looking for nightlife, museums, or a bustling social scene, since the village is genuinely small and low-key. For slow travelers or hikers passing through Mendoza province, one or two nights delivers real value.
Yes, it's easily done as a day trip from Mendoza city given the roughly one-hour bus ride each way, and many travelers visit just to hike or see the reservoir before returning the same evening. That said, staying at least one night lets you catch the reservoir at sunset and sunrise, which day-trippers miss entirely.

We 💚 feedbackParting advice and final tips

Potrerillos earns its place on a slower Mendoza itinerary because of the quiet, the reservoir light at dusk, and hikes you can do without booking a tour. The drawback: there's genuinely little to do after dark, and if you crave hostel energy or nightlife, one night here will feel like plenty.
