Backpacking in Campo de Piedra Pómez
👍 Recommendedunique site ranked #6
By Johan Kruseman 🇳🇱 | Updated October 19, 2026

Forget the drone shot of white rock that made this place famous online. That photo tells you nothing about the silence out there, or the wind that never stops. Campo de Piedra Pómez sits inside the Antofagasta de la Sierra region of Catamarca province, a pumice stone field carved into towers and mushroom shapes by volcanic explosions and centuries of erosion. Crowds are thin because getting here is a genuine haul on dirt roads. Costs stay low if you're organizing your own transport, higher if you book a tour from Antofagasta de la Sierra or Fiambalá. I remember crouching behind a pumice pillar at sunset, grit in my teeth, watching the whole field turn the color of raw bone. No filter needed. The payoff is real, but only if you respect the distance and the isolation getting there demands.

✨ Why go?
Ranked #6 unique site in Argentina
What sets this place apart

You go because nowhere else in Argentina looks quite like this. The volcanic pumice formations stretch for kilometers, sculpted into shapes that shift as the light moves, and you won't find anything comparable elsewhere on the continent. It's genuinely low cost once you're in the region, especially if you split a vehicle with other travelers heading the same direction. The effort-to-reward ratio is high: a rough dirt road gets you access to something almost nobody back home has seen. Most backpackers fold it into a longer loop through Catamarca's high desert, pairing it with the Antofagasta de la Sierra route or connecting toward Fiambalá and the Paso San Francisco corridor. It rarely works as a standalone trip since the nearest towns are small and remote, so treat it as one striking stop … read more 👉

💡 HighlightsPlaces and moments you shouldn't skip

  1. The Pumice Towers
    These wind-carved columns are the signature image of the site, rising in clusters like frozen waves. Some reach several meters tall, shaped entirely by centuries of abrasive wind rather than human hands.
  2. The White Expanse at Midday
    Under full sun, the pumice field turns almost blinding white. It's disorienting in a good way, like walking across a landscape with no reference points.
  3. Sunset Light Show
    As the sun drops, the pumice shifts from white to gold to a deep rose color within about twenty minutes. Bring a jacket, the temperature drops fast once the sun goes.
  4. The Mushroom-Shaped Rocks
    Erosion has carved certain formations into distinct cap-and-stem shapes. They're scattered enough that finding your own favorite feels like a small discovery each time.
  5. Views Toward the Surrounding

    Erosion has carved certain formations into distinct cap-and-stem shapes. They're scattered enough that finding your own favorite feels like a small discovery each time.
  5. Views Toward the Surrounding Volcanoes
    The field sits within a volcanic basin, and on clear days you can see the peaks responsible for the original pumice deposits, a rare chance to connect the geology directly to the landscape.
  6. The Silence
    Not a visual highlight, but worth listing anyway. There's no ambient noise out here beyond wind, no birds, no distant traffic. It's a rare kind of quiet.
  7. The Access Road Itself
    The drive in through the Catamarca high desert passes salt flats and rock formations that rival the main site. It's part of the experience, not just a means to reach it.
  8. Photography at Different Times of Day
    The pumice reflects light differently morning versus evening, so if you have flexibility, visiting twice at different hours reveals a genuinely different-looking place.

🌤️ When to go?Best time to visit Campo de Piedra Pómez

  • Dry Season (April to November): This is the most stable window, with clear skies and minimal rain. Days run mild but nights drop hard, often below freezing.
  • Summer (December to March): Warmer days, around 20 to 28°C (68 to 82°F), but afternoon winds pick up and can carry dust across the field.
  • Winter (June to August): Cold, sometimes down to -10°C (14°F) at night. Daylight is shorter, roughly 10 hours, so plan arrival with margin.
  • Crowds: Always sparse given the remote access, but slightly busier during Argentine summer holidays in January.
  • Prices: Tour costs from Antofagasta de la Sierra stay fairly steady year-round, with minor upticks during peak summer months.
Go early morning if you can. The light is softer, the wind hasn't picked up yet, and you'll likely have the whole field to yourself.

Antofagasta de la Sierra, 63 km from the field, is the main base, a small town that functions as the regional hub for anyone exploring this part of Catamarca. The tiny village of El Peñón, 35 km away, is the closest settlement. It has basic guesthouses and a handful of small eateries, and it's where most tours and shared transport to the pumice field originate.

Antofagasta de la Sierra, 63 km from the field, is the main base, a small town that functions as the regional hub for anyone exploring this part of Catamarca. The tiny village of El Peñón, 35 km away, is the closest settlement. It has basic guesthouses and a handful of small eateries, and it's where most tours and shared transport to the pumice field originate. Staying here means shorter travel time to the site and easier access to fuel, supplies, and other travelers heading the same direction, useful for splitting costs on a vehicle. Fiambalá is a secondary option, further away but with a slightly wider range of budget accommodation and better connections if you're continuing toward the Paso San Francisco route into Chile. Both towns are small enough that solo travelers tend to run into the same handful of other backpackers repeatedly, which makes coordinating shared trips easy. Neither option offers party-hostel energy. This is a quiet, practical part of Argentina, and accommodation reflects that: simple, functional, and focused on getting you rested for early departures into the desert.

👛 Costs (as of 19 October 2026)Typical daily expenses

Campo de Piedra Pómez costs a self-sufficient backpacker about US$45 to 82 a day, and the biggest line item is the transport that gets you out to the white pumice dunes in northern Catamarca. Entry to the field itself is free or a token fee at a ranger post, and you pay in Argentine pesos, so carry cash because there are no ATMs near the site.

Entry feeUS$0 to 3Little or no charge at the access point; small donations or local fees may apply.

FAQTraveler FAQ

Campo de Piedra Pómez is a volcanic pumice field in Catamarca province, Argentina, formed by eruptions from the Cerro Blanco volcanic complex. Wind erosion carved the deposits into towers and rounded formations that spread across several kilometers of white terrain. It sits within the Antofagasta de la Sierra region of Argentina's northwest high desert.
Most visitors spend two to three hours walking and photographing the main formations, though a half-day allows time to explore further and catch better light near sunset. Given the long drive required to reach it, many travelers treat it as a full-day outing including transport.
Access typically starts from Antofagasta de la Sierra, reached by dirt roads from Catamarca city or via Fiambalá, roughly several hours of driving depending on the route. The province asks visitors to keep to marked tracks in a 4x4 with a certified guide, so join a tour or hire a driver-guide, since public transport doesn't reach the site directly.
⚠️ Things can change over time, so always validate details locally before you go.

We 💚 feedbackWhat to keep in mind

Worth it for that first moment the pumice catches the sunset light, genuinely nothing else in Argentina looks like it. The drawback is real though: the access road is long, rough, and unforgiving on cheap tires. Budget extra time and a decent vehicle, or join a tour instead of gambling on it solo.

✈️ When did I visit Argentina?
I have visited Argentina, together with Chile, in September 2012.
