Kīlauea Iki is a smaller caldera located next to the larger more active Kīlauea caldera. Since the Kīlauea caldera floor has been closed to hikers due to volcanic activity, Kīlauea Iki is as close as you're going to get. The Kīlauea Iki trail starts on the crater rim and drops down to the caldera floor. You get to walk across the entire breadth of the caldera floor seeing different kinds of lava, stream vents, sulphur, and all that volcanic goodness.
Walk through an area concentrated with stream vents. The vents are piles of rocks and out of them pumps a constant flow steam and sulphur dioxide. You can get up right next to them. The gas coming out of them is warm to hot and suffocating. The rocks are covered in a coating of crystalline sulphur.
Hike through a lava tube left by an underground flow of molten lava. The tube is completely dark so bring a flashlight.
