For our recent 4-day adventure to the Big Island, we decided that wanted to visit the summit of Mauna Kea. To get to the summit, one must drive up the infamous Saddle Road. Many locals will tell you that Saddle Road is a very dangerous road to drive on. In fact, a portion of the 16 mile road, just past the visitor center, is unpaved and very rugged. To aid in our excursion through Saddle Road and to maintain the limited warranty on our rental vehicle, we decided on going with a tour group led by Hawaii Forest & Trail. The last thing that we needed was a flat tire on our Mustang at 13,000 feet with no cellular signal available .
