My wife & I wanted to tour the 2018 Kilauea eruption area with a guide without having to start a 6-hour tour in Hilo that included other stops that didn't interest us. Scott's Apau Hawaii Tours filled this need. You're basically buying his time and truck (seating for up to four guests) at a flat rate. He'll take you where you want to go with a descriptive narrative to go with it. He lived through this eruption. Before our tour, I did send Scott a request that he replied negatively to. However, out of the blue during our tour, he said "I don't normally do this," and proceeded to take us to exactly what I requested and that was the highlight of our day. I guess my advice is to go ahead and ask for whatever you want to do and see and you might just get it. Scott's lava lot has a route mapped out where he tells you about all of it as you go through it. If you can't do the three hour tour, the one hour at his lava lot is worth doing. And, he encouraged us to take some lava rocks as souvenirs. Since doing that is prohibited at HVNP, this too was a special treat. He also has complimentary water for his guests and provides hiking sticks. He was in no hurry to finish the tour, even as we exceeded three hours. Highly recommended.
