Hiking the Mauna Kea Summit Trail

Hiking the Mauna Kea Summit Trail is an exhilarating experience for those seeking adventure and breathtaking views. Located on the Big Island of Hawaii, Mauna Kea is a dormant volcano and the tallest mountain in the state. Its summit, standing at 13,796 feet above sea level, offers panoramic views of the island and a unique opportunity to witness the stars like never before. Here, we will delve into the details of the hike, the challenges and rewards that come with it, and some tips to make the most out of your experience.

The Mauna Kea Summit Trail

The Mauna Kea Summit Trail is a strenuous hike that covers 6.3 miles each way, making it a total of 12.6 miles roundtrip. The trailhead is located at the Mauna Kea Visitor Information Station (VIS) at an elevation of 9,200 feet. The trail is well-maintained and marked, but the altitude, steep inclines, and unpredictable weather make it a challenging hike.

The first mile of the trail is relatively easy, consisting of a gradual incline on a gravel road. However, as you reach the second mile, the trail becomes steeper and more rugged, with loose rocks and gravel. The next mile is the most challenging part of the hike, where you will be hiking up steep switchbacks that lead to the summit. The trail can be slippery and unstable, especially in wet or icy conditions, so it is essential to take your time and watch your step.

As you climb higher, the temperature drops drastically, and the air becomes thinner, making it harder to breathe. Many hikers experience altitude sickness, so it is crucial to acclimate yourself to the altitude before attempting the hike. Additionally, the weather on Mauna Kea is unpredictable, and it is not uncommon for hikers to experience sudden changes in temperature, strong winds, and rain. It is essential to come prepared with warm clothing and rain gear.

The Rewards

The challenges of the hike are undoubtedly worth it for the rewards that come with reaching the summit. As you ascend, you will witness some of the most stunning views in the world. The Big Island’s diverse landscape, from lush rainforests to barren volcanic rock, can be seen from the summit. On a clear day, you can see all the way to Maui and even the summit of Mauna Loa, another active volcano on the island.

The most remarkable experience on the summit, however, is stargazing. Mauna Kea is home to some of the world’s most advanced observatories, and the lack of light pollution and clear skies make it an ideal location for stargazing. The visitor information station offers nightly stargazing programs, where you can view the stars through telescopes and learn about the constellations from knowledgeable guides.
