Yes, if you go with an established tour operator. Thousands of visitors do this each year. You'll be given basic safety gear and paired with a guide who knows the tunnels. That said, it's physically demanding and the altitude is extreme-spend a day acclimatizing in Potosí first if you're coming from sea level.

Mine tours run regularly and you can typically book a day or two in advance. If you're traveling solo or in a small group, private tours give you more flexibility on timing and pace-worth booking when you arrive in town.

May through October offers dry weather and clear skies, especially if you're heading to Salar de Uyuni afterward. The rainy season (December-March) makes roads rougher and visibility poorer, though tours still operate. Check before you go for current conditions.

Absolutely. Private tours mixing the active mine with surrounding sites let you see more in one day. Many visitors also book a private 4WD from Potosí directly to Salar de Uyuni, cutting out the need for separate transfers.

Expect a guide, entry to the mine, and basic safety equipment. Most operators include a stop at the miners' cooperative where you can buy coca leaves and supplies as gifts. Lunch and hotel pickup vary by tour-check what's covered when you book.

The city center is walkable, though the altitude hits hard at first. For mine tours and longer trips, private minivan or SUV transfers are the standard way to go. If you're staying a few days, hiring a private driver for a city tour and surrounding sites makes sense.

Yes. The city has good museums covering its colonial and mining heritage, and a half-day walking tour shows you the plazas and architecture. Most visitors split time between the mines and the town itself-they complement each other well.
