Here's a stunning 4k drone video from one of Chile's lesser-known provinces. It's called Bio-Bio, and it's one of the 16 administrative divisions (states) that make up the South American country. It's located about 2/3 of the way down Chile's long Pacific coastline. It's capital city Concepcion is the country's third largest, and it's one of the most developed parts of the country. It's also known for its stunning mountain scenery, which is on full display in this beautiful drone video by nuclearcl.
