Kilauea has been flowing for the past 20+ years. The only place to see an active flow is either from the air via a helicopter tour, or to drive down the Chain of Craters Road to the ocean where the flow enters the ocean. A recent flow entering the ocean is reported to be within a half mile walk from the parking area, whereas in the past it was over a mile away. The Information Center at the park is the best place for current information. From the Kona side, there are two routes to the park. The long way is around the south perimeter of the the island, which will take you past the coffee farms, the City of Refuge (old Hawaiian "Get Out of Jail Free" place) and South Point (southern most point in the US) till you head north to the park. The drive, 90 or so miles non-stop, is about 2 hours each way. The "other way" is to take the Saddle Road, which goes between Mauna Loa and Mauna Kea. While a little faster, it's a "driver's road" if you know what I mean. I'd take that route if I driving alone with an AMG 55 anything to take the curves, dips and climbs, but not with the wife and child.
