My family is taking a trip to Hawaii and plan to spend a day in the park. We will be driving in for a day trip and do not plan on spending the night (we already have firm hotel reservations in Kona). What is the best way to see the park? We are all in decent physical shape, so I was wondering which is best: bike, car, walking tour, boat? Our main goal would be to see lava (which I heard may not be possible at this time?), so I would appreciate any tips on the best way to tour the park.
