Getting around The Big Island on public transport is infrequent. If you don't drive and are on a low budget (which makes tours uneconomical)
then you aren't going to see the best of the Big Island.
Having said that the buses are free!
Volcano National Park - Halema'uma'u is currently erupting and is quite
spectacular. Nearby is the Thurston Lava Tube and the Chain of Craters
road, really reminds you of the power of the volcano. Stay in Volcano
Village.
