About Mauna Loa

Mauna Loa is the largest active volcano on Earth in terms of volume and area covered. It is an active shield volcano located on the island of Hawaii in the U.S. state of Hawaii. It stands over 13,000 feet tall(4,169 m) and has a base that covers an area of over 2,000 square miles.


Things to Do at Mauna Loa

Mauna Loa is a large and complex volcano and presents a challenging hike offering breathtaking views of the surrounding landscape. The summit of the volcano is at a high altitude and the trail is over rough, jagged, and often loose lava. The trail is marked with stacked rocks and can be very easy to lose in times of low visibility. There are two trailheads to the summit:

  1. From Mauna Loa Road: 12.1 km from Mauna Loa Lookout to Puʻuʻulaʻula, 18.7 km from Puʻuʻulaʻula Cabin to Summit Cabin with significant elevation gains.
  2. From Mauna Loa Observatory Road: 9.5 km from Mauna Loa Observatory to Summit Cabin, 10.3 km from Mauna Loa Observatory to the summit.

Only 3 consecutive nights can be spent at every cabin. Only a limited number of hikers are allowed per night at the cabins. 24 hikers are allowed per night at the Pu'u 'ula'ula (Red Hill). A total of 28 hikers are allowed at the Mauna Loa summit cabin area. There is no drinking water at any of the cabins or the trailheads. Neither has public telephones or public transportation.

While you are on the trail, be prepared for severe winter conditions, including blizzards, high winds, and whiteouts. Snow or driving rain is possible at any time of year. High-altitude storms can occur without warning. Temperatures are below freezing at night all year round.

As you will be hiking at high altitudes under rigorous conditions, altitude sickness is common. The only cure is to descend and pace yourself and drink plenty of water. Packing extra clothing and waterproofing your sleeping bag will be of help in dire situations. Always try to keep warm as hypothermia is a killer here. A first aid kit will also come in handy to be prepared to treat injuries caused by falls on sharp, glassy lava.

If you do not want to hike up, there are also options to reach the summit using a 4x4 vehicle through the narrow, unpaved road.

Mauna Kea is also known for its ts world-class stargazing. High altitude, no light pollution, and a thin atmosphere contribute to excellent conditions for viewing Hawaii’s night sky with the naked eye. Stargazing conditions are best at the Visitor Information Station, rather than the summit. In addition, the volcano offers spectacular sunrise and sunset from its slopes.

History of Mauna Loa

Mauna Loa is one of five subaerial volcanoes that make up the island of Hawaiʻi. Like all Hawaiian volcanoes, it was created as the Pacific tectonic plate moved over the Hawaii hotspot in the Earth's underlying mantle. It is believed that Mauna Loa started as a submarine volcano, gradually building itself up through underwater eruptions before emerging from the sea through a series of eruptions about 400,000 years ago. Since then, the volcano has remained active, with a history of effusive and explosive eruptions.

With a submarine height of 5,000 m and subaerial height of 4,170 m, Mauna Loa rises 9,170 m from base to summit, greater than the 8,848 m elevation of Mount Everest from sea level to its summit. Much of the mountain is invisible even underwater: its mass depresses the crust beneath it by another 8 km, in the shape of an inverse mountain, making the total height of Mauna Loa about 17,170 m.

Mauna Loa's summit has two prominent rift zones, marked on the surface by well-preserved, relatively recent lava flows and linearly arranged fracture lines intersected by cinder and splatter cones. These rift zones are believed to reach down to the volcano's base, 12 to 14 km deep.

More information on the history and expeditions of the eruption can be read here.

Best Time to Visit Mauna Loa

Mauna Loa is located in the tropical rainforest region of Hawaii, and the weather can vary significantly depending on the time of year. The dry season, which runs from April to October, tends to have more pleasant weather with less rain and fewer clouds.
