Backpacking in Mar de Ansenuza
👌 Worth visitingunique site ranked #10
By Johan Kruseman 🇳🇱 | Updated October 19, 2026

The salt crust near the shore can hold your weight one meter in and swallow your boot the next, so test every step before you commit. Mar de Ansenuza sits in northeastern Córdoba province, one of the largest salt lakes on the planet, and it's nowhere near the backpacker trail. That's the trade-off. No crowds, no entrance fee, barely any infrastructure. I floated on my back in water so dense I could read a paperback held above my chest, salt crystals stinging a scrape on my knee like tiny needles. The photo potential is real (pink hues, mirror flats) but you need your own transport and patience for a place that offers zero hand-holding.

✨ Why go?
Ranked #10 unique site in Argentina
What makes this unique site worth visiting

Backpackers detour here because the payoff is disproportionate to the effort: a few hours off Argentina's main gringo trail gets you total solitude at one of the world's biggest salt lakes, no ticket booth in sight. It's essentially free, aside from transport and maybe a boat ride with a local operator in Miramar. The buoyancy alone justifies the trip, denser than the Dead Sea in some readings, and you won't share it with tour buses. It also slots naturally into a Córdoba province loop, pairing with the Sierras or a Rosario-to-Salta overland run, so you're not burning a dedicated flight or multi-day detour just for one lake. For travelers chasing authentic, undercrowded nature over polished tourist infrastructure, it delivers exactly that.

💡 HighlightsKey sights and experiences for travelers

  1. Floating in the hypersaline water: The salt concentration is high enough that you bob like a cork with almost no effort. It's the single most memorable physical sensation the lake offers.
  2. Flamingo colonies: Thousands of flamingos feed in the shallows, especially in spring. Bring binoculars, they keep their distance.
  3. Miramar town: The old resort town on the lake's edge has faded, slightly eerie charm, with flooded hotels hinting at its mid-20th-century heyday as a spa destination.
  4. Salt flat photography: When the water recedes, the exposed salt crust creates mirror-like reflections at sunrise and sunset, similar in effect to Bolivia's Salar de Uyuni but on a smaller scale.
  5. Bird-watching beyond flamingos: The lake and surrounding wetlands host black-necked swans, coots, and migratory shorebirds,

  5. Bird-watching beyond flamingos: The lake and surrounding wetlands host black-necked swans, coots, and migratory shorebirds, making it a genuine stop for serious birders.
  6. Boat trips with local guides: A handful of operators in Miramar run short boat excursions, giving you a different angle on the lake's scale that you can't get from shore.
  7. The abandoned bathhouse ruins: Crumbling concrete structures half-swallowed by salt crust, remnants of a spa boom that collapsed after the 1977 to 1981 floods. It's a strange, quiet place to wander, equal parts sad and fascinating.
  8. Stargazing: With almost no light pollution and flat, open horizons, clear winter nights deliver a sky thick with stars, a solid payoff if you're camping nearby.

🌤️ When to go?Weather, crowds, and seasonal trade-offs

  • Summer (December to February): Hot, 28-35°C (82-95°F), ideal for floating and swimming, but intense sun means you'll want a hat and reef-safe sunscreen since there's minimal shade.
  • Autumn (March to May): Mild, 15-24°C (59-75°F), fewer bugs, comfortable for exploring the shoreline without overheating.
  • Winter (June to August): Cold, 5-15°C (41-59°F), water too chilly for most swimmers, but skies are clear and daylight is shorter, around 10 hours.
  • Spring (September to November): Warming up, 15-25°C (59-77°F), birdlife (flamingos) is most active, and crowds, what few there are, stay minimal.
Go early morning in summer before the heat turns the salt flats into a glare-blasted furnace.

🛏️ Where to stay?Where staying makes the most sense

Miramar is your base, the small town directly on the lake's southwestern shore. It's modest, quiet, and built around the salt lake's old tourism identity, so you'll find guesthouses and campsites geared toward budget travelers rather than luxury resorts. Staying here puts you within walking distance of the shoreline and any boat operators, which matters since public transport around the lake is thin. Camping is a legitimate option in designated areas near town if you want to cut costs further and catch sunrise over the salt flats without an early drive.

Miramar is your base, the small town directly on the lake's southwestern shore. It's modest, quiet, and built around the salt lake's old tourism identity, so you'll find guesthouses and campsites geared toward budget travelers rather than luxury resorts. Staying here puts you within walking distance of the shoreline and any boat operators, which matters since public transport around the lake is thin. Camping is a legitimate option in designated areas near town if you want to cut costs further and catch sunrise over the salt flats without an early drive. Avoid trying to base yourself in Córdoba city and day-trip out, it's roughly 200 km away and eats your whole day in transit. Miramar's small size also means it's easy to meet other travelers, since everyone passing through ends up at the same few spots for meals or boat trips.

FAQCommon questions from travelers

Mar de Ansenuza is one of the largest saline lakes in the world, located in northeastern Córdoba province, Argentina. Its hypersaline water, denser in some periods than the Dead Sea, allows swimmers to float effortlessly, and it's also a Ramsar-listed wetland supporting large flamingo populations.
A single day is enough to swim, walk the shoreline, and visit the abandoned bathhouse ruins in Miramar, but staying two days gives you time for a boat trip and proper bird-watching, especially at sunrise when the salt flats reflect light best.
Most travelers reach it via Córdoba city, roughly 200 km away, taking a bus to Miramar and then arranging local transport or a short taxi ride to the shore, since there's no direct public transit to the water's edge and a rental car offers the most flexibility.
⚠️ Things can change over time, so always validate details locally before you go.

We 💚 feedbackSumming up the experience

Worth it for the sheer strangeness of floating in a lake this dense while flamingos work the shallows nearby, no crowds, no fences. The drawback: you're on your own for transport and info, and the abandoned bathhouses hint at how quickly this place could flood or fade again.
