Spent two nights in Volcano National Park last week and both nights were able to view lava flowing. The lava appeared to stop about 2/3 the way down the mountain, never reaching the sea. The Rangers said that the flow changes daily so I recommend checking the report at the Visitor Center at the park's entrance. The hike to the lava's edge takes about three hours (roundtrip) as was told to us by some hikers that had just made the hike. We didn't go that far because we had to hike over mounds of lava rock which proved a little on the difficult side after nightfall. We did see some cool views though. Have a good time!
