I want to travel to Big Island (Hawaii) and visit the Mauna Kea. I want to go to the top of the volcano. My problem is that I haven't got a driver licence and I will travel alone. The organized tours are $200. It is extremely expensive for me. I can walk on foot from the Mauna Kea Visitor Center to the top but how can I reach the Visitor Center? Is there any public bus which go to the Visitor Center? Taxi is expensive for example from Hilo to Visitor Center?
Thank you in advance your help.
