Did a loop down the Halema'uma'u trail to the main crater floor then back up to the ridge and down again through Mauna Iki. Interesting experience especially after having seen the eruption video in the vis. center.
Cloudy and rainy, but an awesome hike. The rainforest at the beginning and end of the trail are quite a contrast to the spooky crater. Very ominous walking through barren crater bottom. It was cool and early in the day when we did it, and a lot of the steam vents on the bottom were clearly visible.
