We enjoyed the portion of the tour spent in the volcanoes park more so than the sites of Hilo, although they were certainly interesting. This is the best tour we have had in a volcanic region. It is a busy day with many stops. It is important to return promptly to the vehicle so that the entire group will have adequate time at subsequent stops. The guide was very pleasant and knowledgeable and kept us moving. Our guide purchased sandwiches for us at the beginning of the tour in lieu of having a lunch stop, and this saved a great deal of time.
