Driving to the top of Mauna Kea Volcano in Hawaii
Highest elevation: 4.207 m (13,803 ft)
The distance covered in this video is 19 km, and the elevation gain is 2.146 m. The average slope percentage is 11 % but there are sections up to 17%. The road is paved, except for an 8 km section in the middle, for which a 4×4 vehicle is recommended.
As at 4.000 m altitude there is almost 40% less oxygen than at sea level, respiratory problems are possible, so everyone has to stop at the visitors center for at least 30 minutes for acclimatization, while people with health issues are advised not to climb to the top.
The climate conditions on the top can be harsh and can change rapidly. Even though Hawaii has generally a tropical climate, during winter time on the top you can find up to 2 m of snow.
