The total round trip distance is 43.2 miles assuming you visit both the summit cabin and the true summit, and usually takes 3-4 days. There are two cabins to stay in along the way. It can be hot since there is no shade available for much of the route, and it is almost always cold on top. The trail is long, but not overly steep or difficult. Mauna Loa Trail The Mauna Loa Trail is the longest, but interestingly, for years was the most popular trail on the mountain (it seems in the last decade a lot of the traffic has switched to the Observatory Trail). The huge mass of Mauna Loa as viewed from the slopes of Mauna Kea. Its sister peak, Mauna Kea is the other contender and which peak is actually higher above its base is often contended. In any case, Mauna Loa rises at least 33,000 feet above the sea floor, making it the first or second highest mountain in the world above its base. This makes the volcano's summit about 17000 meters/56,000 feet above its base by some measurements, although that is a somewhat dubious definition of a mountain base. So, how big is Mauna Loa? It is approximately 375 times the size of Mount Hood, and has quite a bit more rock than either the entire Cascade or Sierra Nevada mountain ranges, or to fill the Grand Canyon 18 times! In addition to the 5000 meters/16,000 feet of the mountain that is under the ocean, it is also known that Mauna Loa depresses the sea floor 8000 meters/26,000 feet. An Oregon State Study (the link is now gone) claims that Mauna Loa is composed of 68,750 to 79,343 cubic kilometers of material, or 16,494 to 19,035 cubic miles of material, of which only a small part is above the ocean. Mauna Loa is known as a shield volcano because such volcanoes are similar to a shield lying on the ground, and always have very gentle slopes. From the ground, it only appears to be a small hill because the slopes of the peak are so gentle. "Largest" Mountain in the Worldīy far and away, Mauna Loa is the largest mountain in the world.

Mauana Loa’s summit is often snow-covered.The summit of Mauna Kea, another Hawaiian volcano, is slightly higher than the peak of Mauna Loa.Mauna Loa, a name of Hawaiian origin, literally translates to Long Mountain.This is greater than the height of Mount Everest. Mauna Loa rises from the sea floor, and its height from its base to its summit is 9170 metres.Mauna Loa has long, gradually slanting slopes that extend to the sea floor.It has been estimated that Mauna Loa has been active for 700,000 years.Eruptions of Mauna Loa tend to be non-explosive and feature lava fountains.In 1942 it was feared that the eruption of Mauna Loa in that year would act like a beacon and attract a Japanese bombing run on Hawaii during World War 2.Its last eruption was in 1984 and since the 1840s it has erupted at least 30 times. Map of Hawaii showing the location of Mauna Loa. It has an estimated volume of 75,000 cubic km, and its magma chamber extends about 3 miles below sea level.Mauna Loa is a shield volcano, a type of volcano known to grow to colossal sizes.Four other volcanoes (Kohala, Mauna Kea, Hualalai and Kilauea) form the other 50% of the island. It has an area of 5,271 sq km (about 2,000 sq miles) and makes up just over half of the island of Hawaii.
Mauna Loa is the largest volcano in the world (in terms of its area and volume).Here are some facts about Mauna Loa, one of the volcanoes of Hawaii.
