Hawaii Island was born from five different volcanoes, two of which are still active.
Kohala is on the northern side of the island. Hualalai is in the west, Mauna Kea and Mauna Loa are toward the center of the island and Kilauea is located on the eastern side of Mauna Loa. Mauna Loa and Kilauea, the youngest of the volcanoes, remain active and erupt intermittently, sometimes spewing fiery lava streams flowing down the mountains to the sea. Lava comes in two forms, the smooth, ropey pahoehoe lava and the jagged, rugged a’a lava.
The quintessential Hawaii Island adventure can be found at Hawaii Volcanoes National Park. At Mauna Loa nearly 14,000 feet above sea level you will be nearly on top of the world at this remarkable park. Ten different day hikes are available within the National Park that range from easy: 1.5 miles or less to moderate: 1.5 to 2.5 miles to challenging: 4-7miles.
All of your senses are alive at the sight of an active volcano, the sound, the smell and the heat creates an unforgettable experience.
