Mauna Kea Trail
The Mauna Kea Trail' is an annex of the Saddle Road that is considered the easiest route to the summit of Mauna Kea volcano, the highest volcano on the island of Hawaʻi. The trail is 6 mi (10 km) long and loosely follows an unmaintained dirt road. Iron poles mark the path every 500 ft (152 m)
The trail starts at the Onizuka Visitor Centef at 9,200 ft (2,804 m), which can be easiy reached by car. From 10,000 to 11,000 ft (3,048 to 3,353 m) the path consists of scree. From 11,000 to 12,800 ft (3,353 to 3,901 m) the area is predominently a'a lava flows and is not as steep. At 131,300 ft (40,020 m) the road forks, with one path going to Lake Waiau and the other fork to the summit.
The summit region is typically very cold, and sunscreen for protection from UV rays is recommended. Water is also recommended, although Lake Waiau is also drinkable.
