A low sun throws long shadows across white sand ridges as a 4x4 threads a path between dunes, and the nearest lagoon catches the sky like a mirror. You feel the vehicle climb, slide, and settle; the guide points to a pocket of water tucked in a hollow — a cool, clear lake waiting for a quick swim.

Carry at least 2 liters of water; guides may stop for drinks but availability is limited on dune crossings.
