The reality is that Provincial Route 43 is paved along its main stretch, from the junction at Puerta de Corral Quemado / Villa Vil, through Cuesta de Randolfo and Villa El Peñón, until reaching the main town of Antofagasta de la Sierra.
While Provincial Route 43 is paved and allows vehicle traffic under normal conditions, access to tourist attractions such as Campo de Piedra Pómez (Pumice Stone Field), Salar de Antofalla (Antofalla Salt Flat), and the Galán Volcano Crater is limited. These areas can only be reached via hard sand, Puna rocks, and dune fields. For these off-road excursions, 4x4 traction and the company of licensed local guides are mandatory.

Stay hydrated with bottled water, avoid heavy meals before the ascent, and consume coca tea or candies to help alleviate the effects of altitude sickness.
In the Randolfo area, it's common for the wind to blow sand onto the asphalt road. Drive with caution, reduce your speed, and keep your low beams on.
