This is a tough review to write. For content, we would give a 5. The volcano expert accompanying the driver knew his stuff. This pretty much saved the day. You will visit all places highlighted in the tour, but no views of flowing lava. Amazing views though. Ok, now for the ugly -- the vehicle the provider used was totally inappropriate for a 10-12 hour day for more than 4 people. Think Joe the Plumber's van with windows - seriously! Try riding in and climbing in and out of the back two rows all day long. Totally lacking!! They have nerve really. Oh, the driver couldn't even find his way back to the resort without help from us. If not for the technical quality of the tour, this view would have been a 1. We usually go direct to Viator when booking tours, having confidence in the quality of their providers. This one definitely has us rethinking our loyalty to the brand. Also, no real time frame given at a stop - so you know how that goes someone always takes far longer while the rest wait.
