We entered Bolivia from San Pedro de Atacama, Chile, on the 1st of May 2015. At this entrance to Bolivia there's no town, no shops and not even a sealed road. There is only a small brick hut that services as the migration or border control office. So we spent a few nights in San Pedro, a big tourist town with all the essentials, to stock up on supplies for the road ahead and for Janell, to squeeze in as many hot showers as she could to build up 'cleanliness credit'.
