Hawai'i volcanoes National Park - Part 2

We started the day with a stop at Halema'uma'u crater. We could see fumes going out of its lava lake at day light. Whereas at night time we can witness a fuming red glow. So later that day, around 7:30pm, we visited the site at night. These days no one can walk closer to the crater, that is under the surveillance of rangers. That site is enormous and does not translate well on picture.
Otherwise we spent the day driving on the Craters Roads, stopped to see several craters filled with solidified lava, we walked on various lava fields and we visited a site with petroglyphs. The road ends on the ocean whose waves crashes on cliffs. A sign says 'road closed' - as they are building a new road there, after a volcanic eruption trashed the place.
