If you have visited Tatio, you might go to Machuca on the way down. This village with only 20 houses and churches now mainly relies on visiting tourists. It's worth a stop and wandering around. It costs 300 pesos to go to the toilet and 1000 photos of people who are asleep. They need our money to survive. The guy is grilling llama meat-didn't try! There is a cafe, I think it is a small hotel now, it is worth stopping, but it does not take long.
