Discover the wonders of Hawaii’s highest volcano while atop its summit and behold a roaring cascade named for the rainbows in its mist. Your immersion into the natural sciences will begin at the Onizuka Center for International Astronomy visitor center, where you will learn about the advanced telescopes on sacred Mauna Kea volcano and about rare endemic plants such as the delicate silversword that only on grows at altitudes above 5,000 feet. Mauna Kea is nearly three times that high and to reach its summit you will ascend in a 4x4 vehicle. The volcano is nicknamed the White Mountain as it is sometimes snow-capped. The views on the way up will be breathtaking as will be the epic vistas that await you at the very top. The sight of Rainbow Falls will also be spectacular as the 80-foot cascade lies within a mango orchard and usually creates rainbows as the sun shines through the plummeting water.
