Check out this stunning drone video from the largest island in Russia's giant Lake Baikal, compliments of multiple Drone Video of the Week Finalist CINEMADRONE. Olkhon Island lies about midway down the long, narrow lake, which is the largest freshwater lake in the world by water volume. The third-largest lake island in the world, Oikhon is about 72 km (around 44 mi.) by about 21 km wide (around 13 mi.) at its widest. Largely covered in forests, the island has a permanent population of less than 2,000, largely aboriginal Buryats.
