I have gone on several Viator tours and have been extremely happy with them all. Shorter lines, things you could not find on your own etc...I thought this tour could have been better, but there were also some great things about it.
The van van was extremely comfortable and not having to drive was great. Rob, our guide did a nice job with the history of the island, which I thought was very informative. We went to the waterfall first. Very nice, had a great time, but I thought we might get closer with a guide. We went in the normal entrance and walked the exact path all others did. Rob brought a camera and took pictures for us. he also gave me the camera and let me take as many as I wanted. The pictures were uploaded at the end for us to view/download.
After that we went to lunch at a local place in Hilo Suisan and had a local dish Pokebowl. Amazing!!! We ate our lunch at a nearby cove where turtles were swimming. Also amazing!
Next the volcano. As this was not my first volcano sighting and the fact that we only got as close as all others tourists I was a little underwhelmed. The lava flowing into the ocean is a must see, although it is hard to get to that area.
In my opinion we could have done this ourselves in our own car but there are some good perks with the tour.
