This is the worst tour I have ever done (and I have traveled extensively around the world). Buyer beware.
Firstly, it was advertised as a 9am to 4pm full-day tour, but we were picked up at 10am and dropped off just after 2pm.
The highlight was supposed to be the Volcano National Park, but we spent only 30mins at the Volcano house lookout and then we left. Our driver was not a guide, so we had no commentary (no advice on how best to see the volcano etc) and we spent a lot of time driving aimlessly back and forth - to accommodate the other couple's helicopter inclusion.
We didn't follow the itinerary at all, we didn't visit or see: Sulfur banks, chain of crater road, visitor centre, volcano steam vents, Macadamia nut factory, Richardson Black sand beach, Wailuku river state park, or get a commentary of historic Hilo.
It was a total waste of our money. We later booked a tour with a different company and they did a great job (Kapohokine Tours).
I have contacted Dynamic Tours several times, but they don't respond.
I'm angry that we paid a lot for this tour and I feel totally ripped off.
