Lower Lake Waiau Trail

While komoot lists this route for jogging, the trail to Lake Waiau is at an extreme elevation of 13,020 feet on Mauna Kea. The thin air makes any strenuous activity, including jogging, very difficult and poses a significant risk of altitude sickness. It is generally recommended to undertake this trail as a slow hike rather than a run, even for experienced athletes, due to the physical demands of the high altitude and rugged terrain.

The trail is characterized by a dusty and volcanic path, primarily composed of loose cinder and lava rocks. You may encounter scree and rough a'a lava flows, which require careful footing. The rugged nature of the path, combined with the high altitude, makes for a challenging experience.

The trail to Lake Waiau is accessed from the Mauna Kea Access Road. Specific parking details for the trailhead are not provided, but visitors typically drive up the access road. It's crucial to acclimatize at the Visitor Information Station (9,200 feet) for at least 30 minutes before proceeding further up the mountain.

The komoot tour data suggests a duration of approximately 20 minutes for the 2.38 km route if jogging. However, given the extreme altitude and challenging terrain, most people will find it takes significantly longer, especially if hiking slowly to acclimatize and enjoy the views. Plan for at least 1-2 hours for a round trip hike, including time at the lake.

The trail offers an otherworldly arid environment with panoramic views of cinder cone landscapes. You'll see the distinctive Lake Waiʻau itself, often described as an 'emerald gem' nestled within a cinder cone. On clear days, you might also catch views of Mauna Loa and the observatories near the summit.

Information regarding dogs on the Lower Lake Waiau Trail is not explicitly provided. However, due to the trail's location within the Mauna Kea Ice Age Natural Area Reserve and its sacred cultural significance, it is generally advisable to leave pets at home to respect the natural and cultural environment.

The trail is accessible year-round, but conditions vary. Summer months typically offer clearer, warmer weather, though temperatures at 13,020 feet are always cool. Winter can bring snow and ice, making the trail more challenging and potentially impassable. Always check current weather conditions before heading out, as high-altitude weather can change rapidly.

There are no specific permits or entrance fees mentioned for accessing the trail to Lake Waiau within the Mauna Kea Ice Age Natural Area Reserve. However, visitors are strongly encouraged to stop at the Visitor Information Station (VIS) at 9,200 feet for acclimatization and to obtain current information on trail conditions and regulations.

Yes, the route to Lake Waiau utilizes sections of several paths. The primary trail is the Lower Lake Waiau Trail, but the route also passes through sections of the Mauna Kea-Humu'ula Trail and the Lower Lake Waiau path.

Given the high altitude and remote location, essential items include plenty of water, warm layers of clothing (even on sunny days), sun protection (hat, sunglasses, sunscreen), sturdy hiking boots, and snacks. It's also wise to carry a first-aid kit and inform someone of your plans before you go.

Due to the extreme altitude (13,020 feet) and rugged, volcanic terrain, this trail is not recommended for beginners, young children, or individuals not accustomed to high-altitude environments. The risk of altitude sickness is significant, and the physical demands are considerable. It's best suited for experienced hikers who are well-acclimatized.
