Getting to Mauna Kea
Your adventure starts with the journey. Mauna Kea is located on the Big Island of Hawaii. The summit is accessible by car, but it’s crucial to understand the road conditions and vehicle requirements. The drive up Mauna Kea involves a significant altitude change, and not all vehicles are suitable for the trip. Here’s a breakdown:
Saddle Road (Highway 200): First, you’ll need to get onto Saddle Road (Highway 200), which bisects the island between Hilo and Kona. This road used to have a reputation, but it’s now fully paved and well-maintained. However, it can still be subject to sudden weather changes, including fog and rain, so check conditions before you go. Use caution and drive slowly, especially at night.
Mauna Kea Access Road: From Saddle Road, you’ll turn onto Mauna Kea Access Road. This is where things get a bit more challenging. The first part of the road is paved and relatively easy. However, the road from the Visitor Information Station (VIS) to the summit is unpaved and steep. Four-wheel drive (4WD) is required for this section. Rental car companies often prohibit taking standard rental cars to the summit, so verify the terms of your rental agreement. Some companies, like Harper Car & Truck Rental or various local jeep rentals, specialize in 4WD vehicles suitable for the Mauna Kea summit road. Be prepared to spend significantly more for a 4WD vehicle rental, with prices ranging from $150 to $300+ per day.
Why 4WD is Necessary: The unpaved section is not just rough; it’s often steep and loose. Two-wheel drive vehicles risk getting stuck or losing control, especially on the descent. Also, the sudden altitude changes can affect your vehicle’s performance. For safety reasons, heed the 4WD requirement. If you don’t have a 4WD vehicle, consider joining a guided tour.
Driving Yourself: If you choose to drive yourself, be sure your vehicle is in good working order. Check tires, brakes, and fluid levels before you go. Familiarize yourself with low-range 4WD operation. Drive slowly and cautiously, and be prepared to yield to uphill traffic. Consider purchasing a portable air compressor and tire pressure gauge, as the lower air pressure recommended for off-road driving is different than highway pressures.
Acclimatizing to the Altitude
Mauna Kea’s summit is at 13,796 feet (4,205 meters), and altitude sickness is a real concern. Symptoms can include headache, nausea, dizziness, and shortness of breath. Gradual acclimatization is crucial to enjoying your visit safely.
The Visitor Information Station (VIS): Located at about 9,200 feet (2,800 meters), the VIS is the key to acclimatization. Plan to spend at least one hour, preferably longer, at the VIS before proceeding to the summit. This allows your body time to adjust to the reduced oxygen levels. The VIS offers informative exhibits about Mauna Kea, its cultural significance, and the science conducted at the observatories. You can also purchase snacks and drinks (though choices are limited) and use the restrooms.
Activities at the VIS: Take a short walk around the VIS to gently increase your heart rate and encourage your body to adapt. Attend one of the ranger programs offered throughout the day. These programs often cover astronomy, geology, and cultural aspects of Mauna Kea. In the evening, the VIS typically hosts a free stargazing program, even though the views are better at the summit.
Staying Hydrated: Drink plenty of water to stay hydrated. Dehydration can worsen altitude sickness symptoms. Avoid alcohol and caffeine, as these can dehydrate you further. Bring your own water, as the VIS offers limited options.
Monitoring Your Symptoms: Be aware of how you feel. If you experience any signs of altitude sickness, descend immediately to a lower altitude. Don’t push yourself to reach the summit if you are feeling unwell. Listen to your body.
Who Should Avoid the Summit: Individuals with heart or respiratory problems, pregnant women, and children under 16 should avoid the summit. The high altitude can be particularly dangerous for these groups. Even healthy individuals can be susceptible to altitude sickness, so take precautions regardless of your physical condition.
