The atmospheric Calacala makes a worthwhile trip from Oruro. The site consists of a series of rock paintings of llamas and humans in red and orange tones, presumably dating to the first millennium BC. It’s located under an overhang 2.5km beyond the village of Calacala, which is 26km east of Oruro. Stop in the village to locate the guard who has the keys and collects the fee; she can often be found in the small cafe marked by a rusted Pepsi sign. The site itself is a 30-minute walk past the village, near the old brewery. The views from the site of the exceptionally beautiful valley, which provides some of Oruro’s water, are spectacular. There’s no public transport unless it’s the feast day of Señor de la Laguna (Lord of the Lake) on September 14; a taxi there and back will cost you B$120.
