Before we drove up to the Mauna Kea visitor center, I stopped and rested for about 15 minutes at Pu’u Huluhulu located at the intersection of Saddle Road (route 200) and Mauna Kea access road.
Pu’u Huluhulu is a short hill and the hike to the summit is about 30 minutes long. In sunny days, there are amazing views of Mauna Kea at the summit. When we arrived at around 4 pm, it was cold, cloudy with light showers from time to time. We were totally not used to the temperature, so we decided not to walk uphills. We probably wouldn’t see anything in the fog. It is still a good place to rest a bit after a long drive and to put on pants and jackets.
