We did the Lava Hike a few days ago. What an experience! There were a couple of nice flows, directly into the ocean. Very impressive and the pictures we took were amazing!
For us, the hike was about 2.5 miles to the lava. We started at 4pm. David will provide sticks for you to play in the lava with. We spent almost an hour at the lava site, before we hiked back. That's enough to take all the pictures you want. David provided flashlights for the way back.
All-and-all we the trip will take between 4 - 5 hours. Wear sturdy shoes, but other than that the hike is very do-able, even with smaller children. Beware at the lava site though, because the cliffs are very steep!
This is a must-do trip, when you're visiting the Big Island. There are very few volcano's in the world where you can get this close to the real thing.
David and Charlene's house is very beautiful. For a complete experience, consider staying there the night after the hike. You're right on the lava, totally off the grid. We were sorry we hadn't thought about that before. Sure beats driving back to Hilo for an hour, in the middle of the night!More
