The Hawaii Volcanoes National Park is accessible by Mass Transit Bus, but the timing is limited. Furthermore, destinations within the park are far apart, and the Mass Transit Bus stops right at the Visitors Center. It does not travel through the Park. Viewing the active lava can be tricky and sometimes not possible by ground travel. The best way to view molten lava is from the air by helicopter. If you have rented a car, and are planning to visit the Park on your own, come on by the Hilo Information Center for an in-depth overview of what to see when you’re at the park and on the way.
