I thought that more time could have been spent at the orchid place and at the Mauna Loa factory. Some of the time can be cut from the volcano portion. Eventually it felt like we had seen enough craters.
Hugh was extremely knowledgeable about so many areas, including geology, botany, the volcanoes, and the history of Hawaii. We enjoyed the hike immensely!
The guide was very knowledgeable; the tour was AWESOME, and very educational. Really appreciated him taking us off the beaten path.
