Planning a day trip, leaving Waikoloa early, driving to Hilo just to visit and have an early lunch, and then on to Volcano Park. I realize this is almost 3 hours of driving in each direction. I have 2 questions if I may. First, we will have smallish kids with us(6 and 9) and wont be able to day major hiking, but do want to see some of Volcano park. How far do you really need to go into the park to make it worthwhile? I know we wont see everything, but we would like to see something memorable. Does it require hours of driving once arriving at the park to be worthwhile? Nextquestion is, how difficult would the drive back across be at night? Figure we would have dinner at Hilo before the drive back. Kids would probably sleep on the way back. I dont mind a lengthy nighttime drive but last time i was in hawaii(10 years ago on my honeymoon!) we got bad advice and took the back road back from Hana at night! We felt lucky we survived afterwards! Dont want to do anything dangerous! Thanks a million!
