Today, you’ll head out on a brief guided walk with your leader. La Paz is a city renowned for its markets, especially the Mercado de Hechiceria (the Witches' Market), which sells potions, incantations, stones and artefacts. Ask a local about their significance – most people are happy to explain. Then, you’ll have some free time to explore. Maybe visit the Coca Museum, which isn’t too far from your hotel in the Rosario district. Late this afternoon, leave La Paz on an overnight bus to Uyuni. There are comfortable recliner seats on the bus, but it can be cold on board, so it’s important to bring warm clothing and wear base layers. There’s usually a toilet on the bus, and the driver will make a couple of stops along the way.
