Also known as the volcanic island, the Big Island is an island in Hawaii's islands, erupted by five volcanoes. The top of Mauna Kea on the north side of the island is covered with snow all year round, so the locals call it Baishan. Here is a very good Mauna Kea Observatory that can simultaneously observe the stars in the northern and southern hemispheres. On the southeastern side of the island is the Kilauea volcano, which has been flowing out of lava for twenty years. The volcanic eruptions here are not accompanied by huge explosions and disasters like other places, but rather rather gentle. There are two airports on the island and Kona Airport on the west side, surrounded by more mid-to-high-end resort hotels, suitable for leisure vacations.
