Uyuni tours typically use sturdy 4×4 vehicles built to handle the salt flats and rugged high-altitude desert terrain. Most vehicles carry a driver-guide along with a small group of travelers, making it easier to stop for photos and enjoy the scenery without feeling overcrowded. Vehicle condition, group size, and guide experience can vary between operators, so it is worth checking these details before booking. Choosing a reputable Uyuni tour company can make a significant difference in comfort, safety, and the overall quality of the experience.
