We will hopefully be staying on Kona coast. Is one day enough volcanoes national park? How far is Hilo from there, is it worthwhile to go for an hour or two? What exactly can we do in Hilo?
Also, it seems that people consider Waipo Valley to be on the Hilo side, but from the map it looks like Waimea is closer to Kona and more north. We are trying to plan our itinerary
