Whole-heartedly recommend Dennis and Paul's paradise. It's off-the-beaten path, to the point that when we sat down for dinner our first night in Pahoa, my mind scrambled for the correct language to address the staff. The bungalow is perfect and the landscaped three acres surrounded us with tropical wonder.
They are fabulous--gave us great recs on activities and eats. Unparalleled selection of snorkel gear. Great with communication and directions too. It's about 15 minutes to town and probably best navigated by daylight the first time. We visited Volcano twice in our four day stay and thought the drive was very doable.
PS: Outdoor shower! And great coffee! xox to Miss Felicia, the hostess with the mostest :)
