Uyuni Walking Tours: What's Really There

Search for a self-guided Salar de Uyuni walking route and you will find nothing bookable, and that gap is the first thing worth knowing: setting off on foot across the salt flat alone is one of the genuinely dangerous ideas a traveler can have here. There is no shade, no water, no cell signal, and no visible landmark once the horizon curves away in every direction. Disorientation, sunstroke and severe dehydration in that featureless white void have proved fatal to unprepared hikers, and nights drop well below freezing even when the day was warm. Every real walking option in the region is short, staged from a 4WD, and over in under an hour.

What actually exists on foot

  • Cementerio de Trenes: a roughly 1-hour scramble through the rusted British-built steam locomotives 3km outside Uyuni town, abandoned since the 1940s. Flat, free, and walkable straight from town without a vehicle.
  • Isla Incahuasi cactus loop: a 45-minute stone-paved trail climbing about 60m through cacti over 900 years old to a 360-degree summit view, entry 30 BOB. You still need a 4WD to reach the island itself; only the loop on top is on foot. The full-day salt flat tour from Uyuni bundles the drive with this loop and the train cemetery scramble in one trip.
  • Uyuni town walk: strolling Avenida Ferroviaria past the 1930s clock tower to Mercado Central, where stalls sell Andean potatoes, quinoa and herbal remedies. The only walk on this list that costs nothing at all and needs no transport.
  • Coquesa stroll: a short walk through quinoa fields and llama pasture near Volcán Tunupa to the cave holding the pre-Inca Coquesa mummies (30-40 BOB entry), reached by 4WD from Uyuni.

Altitude, even for short walks

Uyuni sits at 3,670m and Incahuasi at 3,700m, high enough that the 45-minute cactus loop can leave an unacclimatized visitor winded. Spend a day resting in La Paz or Sucre before any of these if you can, drink more water than feels necessary, and skip alcohol the first night.

Budget note

None of the above costs more than the 4WD transport that gets you there and the small per-site entry fee. The Cementerio de Trenes and the town walk cost nothing beyond your own time. For the longer multi-day routes into the Eduardo Avaroa reserve , walking gives way entirely to a shared or private 4WD, and that switch comes with its own safety questions worth reading before you book, covered on the outdoor activities page .

One concrete tip: do the Cementerio de Trenes scramble on your first morning in Uyuni, before any tour departs, since it needs no booking and doubles as a gentle altitude test before a longer day.
