overhead views of the Pu'u O'o vent, which has been
active since the 1980s.
We also hiked in Volcano National Park, which is an incredible place.
Lava from the Pu'u O'o vent is always flowing, but sometimes it's underground and not visible. We were lucky that the lava was above ground while we were visiting. The rangers are the coolest park rangers I've met yet; they let you hike right out to the flowing lava.
Here is part of the hike, where old lava has covered the highway.
Some not so old lava...
