Santa Cruz is in Bolivia's Amazonian Basin, surrounded by jungles, with the hot, humid climate of a rain forest. So the existence of a massive field of sand dunes just sixteen kilometers south of the city is a geological marvel. On our very last day in Bolivia, we visited Las Lomas de Arena, declared a National Park in 1990.
Seven kilometers outside of Santa Cruz, the Biocenter Güembé combines aspects of a resort, a natural recreation park, a swimming pool, and a zoo. We visited for half a day and could happily have stayed for much longer, relaxing by the pool or exploring the grounds more thoroughly.
With our three months in Bolivia almost over, we arrived in Santa Cruz de la Sierra, the country's most populous city. The Department of Santa Cruz is Bolivia's biggest state, occupying almost the entire eastern half of the country. Consider: even though Bolivia is one of South America's "small" countries, the department of Santa Cruz is bigger than Germany! The idea that three months would be enough time to comprehensively explore Bolivia was probably a little naive.
