Hazards Please read before traveling above Hale Pohaku.
Less oxygen is available to the lungs, and acute mountain sickness is common.
Symptoms include headaches, drowsiness, nausea, shortness of breath, and poor judgment. If symptoms of mountain sickness persist or become severe, descend to a lower altitude immediately. High altitude exposure is particularly hazardous for people in poor physical condition, for those with heart or respiratory problems, for pregnant women and their unborn children, and for children and teenagers under 16. It is strongly recommended that people in these categories not travel above the Visitor Information Station. Extended exposure to high altitude can cause permanent damage to young people whose bodies are still developing.
