In a few weeks we will traveling to the Big Island. We will be staying both Hilo and Kona. On our way from Hilo to Kona, what are things we should do? I would like to get to Pololu Valley on our way, but not sure what other stops we can hit. Or how much time we should spend at various spots? We have all day and will not be in a hurry. It will be just me and my wife and we do like hiking. I just would like advice from people who know as to what is reasonable. Thanks.
