Covering 4,085 square miles (10,582 square kilometres), the magnificent, mind-bending Salar de Uyuni is the world's largest salt flat. Your sunrise session begins at 03:30 a.m. and lasts until 08:30 a.m. when your local guide will pick you up from your Uyuni accommodation. The air can be cool here , but the brisk temperatures are worth it for the chance to watch as the sun illuminates the salt field and ignites the sky with colour.  After the pre-dawn drive and magical sunrise, grab your camera to shoot optical illusions created by the distant horizon. Throughout the tour your guide will provide commentary and informative info on the salt flats, and the tour finishes back in the town of Uyuni when you're dropped at the front of your hotel.
