OverviewMauna Kea, on the Big Island, is Hawai'i's highest mountain at 13796 ft (4198 m). Rather than a single peak, Mauna Kea is undefined; it is a series of volcanic cinder cones, some red, some black, pasted onto a gargantuan massif. While it is tempting to draw grand analogies about how Mauna Kea embodies the spirit of Hawai'i itself, the real king mountain of the Big Island is Mauna Loa, which regularly spreads lava flows over a radius of 50 miles in almost every direction. However, because Mauna Kea's slopes are steeper than Mauna Loa's, the former's summit views are better, and its hikes shorter.
The maintained Mauna Kea Trail is 6 miles in length (one way) and climbs 4576 ft (1395 m), starting from the Onizuka Visitor Center, which is at 9200 ft (2804 m). The trail loosely parallels a partially paved summit road, and from the Mauna Kea Ice Age Reserve boundary at 13200 feet to the summit road's high point of 13700 feet, actually follows the road. Getting to the summit from road's end requires a mere 5-15 minute walk and 100 feet of elevation gan. The vast majority of "mountaineers" drive to road's end, which can be kind of discouraging for hikers, especially when the altitude starts kicking in. Aside from the moral superiority you can enjoy from hiking, you'll take in splendid and wild views along the way. (NB: Hitchhiking is not unheard of.)
An interesting side trip is the short jaunt to Lake Waiau, a very shallow lake (no more than 10 ft deep) about a mile and a half from the summit. You aren't supposed to disturb the lake, and you probably wouldn't want to since Hawaiians used to bring the umbilical cords of their babies here and place them in the lake to give them "the strength of the mountain". If you must drink from the lake, however, today's modern filtration systems should take care of any lingering placental matter.
Getting ThereBy car: From either Hilo or the Kona/Waimea area, access the Onizuka Visitor Center via Saddle Road (Highway 200). The Visitor Center is 6 miles upslope on Summit Road, the turnoff to which is near the 28-mile marker off of Saddle Road. Warning! As of March, 2003, there are no signs marking the turn to summit road. Apparently, the signs keep getting stolen. The ranger speculates that it's astronomy students from UH-Hilo, but it's anyone's guess. In any case, the road is prominent, and in the author's recollection, there are no others in the area to confuse with.
Previously, most car rental contracts prohibited travel on Saddle Road, although in April, 2015, asaking11 noted: "Most rental companies now allow rental cars on Saddle Road. There are even a handful of them that will allow you to take them to the visitor center." A car is definitely the best way to get there. Not by car: The problem is the buses don't use Saddle Road. So, use a car by proxy. (Hitchhike). But seriously, don't worry about the car rental agencies? policy. They don?t dust the tires for Mauna Kea dust or anything.
The trailhead for the Mauna Kea Trail is a hundred yards northwest of Onizuka Visitor Center.
Red TapeNo permits or fees. Rangers do ask that you fill out a Visitor Information Sheet and drop it in a box next to the phone at the Visitor Center, but they will only use this information in case of an emergency. If you want to be really concientious, you can even print out a copy of this form before hand! http://www.ifa.hawaii.edu/info/vis/
Note that Mauna Kea is not in the Hawaii Volcanoes National Park. You would be thinking of Mauna Loa, the second tallest peak in Hawaii. Mauna Kea is leased to the University of Hawaii from the 12,000-foot level and up. So they generally take a not-for-profit approach. Hallujah.
If you'd like to part with your money, you can use professional guides http://maunakea.com. This would also solve the "how to get there" problem, if you don't have a car, since these guides will pick you up from centrally located STARBUCKS (TM) in three different places on the Big Island, which can be reached by bus.
Wildlife conservation: Outside the Mauna Kea Ice Age Natural Reserve, hunting is allowed and common. Also, it is interesting to note that there was a very heartfelt and effective campaign to remove mouflon game sheep from Mauna Kea.
When To ClimbGenerally avoid January and February, as winter storms can drop up to 2 feet of snow. However, snow flurries are a definite possibility year round, so be prepared for this peak as you would any almost -Fourteen-er.
CampingNo camping in the area. Acclimatizing is very important since you will more than likely be driving up to the mountain from sea level, or, even below sea-level if you have spending your sun-drenched days scuba-diving. So consider camping at the Mauna Kea State Recreation Area, 7 miles west of Summit Road (the road that goes to Mauna Kea), at about the 35-mile marker on Saddle Road. (Website:http://www.wildernet.com/pages/area.cfm?areaID=HISPMK&CU_ID=110) Try to go during the week, as hunters (of pigs, goats and birds) both local and of the tourist variety usually have dibs on the weekends. If you can't camp, hang out at the Onizuka Visitor Center before making the trek up. You can learn everything you wanted to know, and more, about the different observatories on the summit.

Keep in mind there is no food or gas available on Mauna Kea.
Geology and GlaciologyHikers may note with some incredulity that the Mauna Kea Trail passes through the Mauna Kea Ice Age Natural Area reserve. Glaciologists believe that, at some point in recent geologic history, there was a glacier of some size on this mountain. Hardly surprising, since at its peak 500,000 years ago, Mauna Kea was thought to stand 17,000 feet above sea level. Unfortunately, the author of this page could detect no obvious glacial remnants (rock scouring, rock moraines, glacial cirques, etc.)
Much of the "proof" of glaciers seems to center around the presence of native adze quarries. The natives set up summer residences in excavated caves and spent the months mining a rare, extremely hard volcanic rock that geologists believe could only have been formed by lava intruded under an existing snow or ice field. The rock was prized throughout the Hawaiian islands for use in a variety of stone implements. Beware of carrying off a souvenir, however. Aside from the fact that this is illegal, we can learn from Greg Brady and Scooby Doo, among others, that taking such souvenirs from Hawaii leads to bad luck and zany adventures.
Still, the line between semi-permanent snow field and true glacier is thin. It is possible, even probable, that Mauna Kea had glaciers on its slopes in the late Pliestocene or even in the more recent global cold spells (8000 years ago, for instance). However, given the high frequency of volcanic eruptive events, most, if not all surface expression of glaciers from 8000 years ago will be fully covered by lava today. In any event, the gullies on the mountain's south face are thought to have resulted from snowmelt from glaciers/semi-permanent snowfields.
Lake Waiau, at 13200 feet, was exploited as a source of drinking water by the native Hawaiians at the adze quarries. The shallow lake, which sits in a small crater on the Pu'u Waiau cinder cone, is curiously thought to be fed by melting permafrost. Still, one cannot ignore the possibility of some spring feeding, as the highly porous/permeable volcanic rock produces many other marked springs.
Lava Lovers: Mauna Kea is a dormant volcano. In technical terms, Mauna Kea is a classic shield volcano. They say that it could erupt in the foreseeable future (geologically speaking).
SkiingInteresting side note: Mauna Kea can be skied. There are no lifts or resorts, but when the snow falls on Mauna Kea, usually in January and February and continuing for several months, you can earn your turns and board or ski it. Don?t take your best gear, though, as you will encounter uneven snow coverage over those tough lava rocks. Wouldn't it be worth it, if simply for the novelty of being able to say you skied during your vacation to Hawaii? If you?d rather just go down than have to go up, the people to contact are Ski Guides Hawaii (808) 885-4188, PO Box 1954, Kamuela, HI 96743 (website: http://skihawaii.com/ ). They will provide equipment, transportation to the mountain from their office in Waimea, and once on the mountain, a ride up the mountain after each run.
TriviaIt may also be of interest to readers that according to the Guinness Book of World Record's, Mauna Kea is the world's highest mountain (33,476 ft or 10,203 m) when measured from the ocean floor. Why climb Everest when you can....?
As most people know, Mauna Kea's summit region is home to a great many large telescopes and other space observation instruments. While there are higher mountains and mountains with dryer weather, the atmosphere above Mauna Kea is world-renowned for its lack of atmospheric "wind shear", which causes distortion in visible images.
