We recently used VolcanoDisovery Hawai’i Tours to provide a tour on the Big Island of Hawaii. Arthur met us precisely at the designated time and did a superb job. We had asked for snacks and sandwiches which were provided exactly as specified – and were delicious. Arthur was very knowledgeable about not only the volcanoes but also about the eco systems. We booked a 4 hour tour, but would have enjoyed spending the whole day with him. He even took the time help with night settings on the camera resulting in some great shots of the active lava lake. Should the opportunity arise we will definitely use them again and will recommend them without hesitation.
