Heralded as Bolivia's best museum, the Casa de la Moneda offers a fascinating look back at a time when Potosí was the center of the Spanish Empire's wealth. This mammoth building in the center of the city was the Royal Mint, pressing silver extracted from the Cerro Rico into coins and medallions.
By far the most popular tourist activity in Potosí is a visit to the mines of Cerro Rico. They're still active, so a tour entails walking past soot-covered miners hard at work in conditions that could be straight out of the 18th century. We weren't especially excited about taking a tour, since gawking at people working in such a dangerous profession is more than a bit unseemly. Between accidents and the inevitable lung diseases, it's still rare for a Potosí miner to reach the age of 50. But we couldn't skip out on the city's most famous experience.
Set at 4090 meters (13420 ft) above sea level, Potosí is the highest city in the world and once was its most wealthy, thanks to the silver mines of Cerro Rico. Remnants of Potosí's glorious past are still visible today, as are the vestiges of the exploitation which made Spain rich beyond measure and resulted in the deaths of millions.
By bus, a trip from Sucre to Potosí takes just a few hours, and it's even faster by taxi. But if you're more interested in scenery than speed, check out the ultra slow bus-train, which winds its wobbly way around mountains, lakes and valleys, offering spectacular views every inch of the way.
On the second day of our hike, we woke at sunrise with aching shoulders, backs and legs, but possessed by a strange energy. The Crater of Maragua was within sight, and the promise of restorative thermal baths at hike's end made us eager to get moving. But breakfast and packing up the campsite took longer than anticipated: a delay which would later haunt us...
