I''ve grown fond of National Parks, having explored Yosemite. This is a park far different for its live volcano. How often does one get to see land being born? I would recommend spending two days exploring this park . . .
1) Drive the loop around Crater Rim Drive. I would say the 11-mile drive has numerous scenic points and sights to see. Start at the Visitor Center and take a look at the informative movie. Jump in your car and drive counter-clockwise. Volcanoes House Hotel has wonderful views of the crater. Sulphur Banks is a place I avoided, since it just stinks there. Steam Vents is a quick stop. Jaggar Museum has some scenic vista points. Halemaumau Crater is a small crater within Kilauea Caldera. Thurston Lava Tube is an easy walk through a mostly lit cave . . . a flashlight is absolutely necessary for the last 300 feet of the journey. Kilauea Iki Crater Overlook is quite impressive. One couldn''t begin to imagine how this fiery pit looked in the 1800s when celebs like Mark Twain visited. There are numerous hikes at different points around the crater. Kilauea Iki Hike takes you from a rainforest atmosphere to the inside of a smaller crater.
2) I''d advise loading up on gas in Volcano Village before attempting the Chain of Craters Road (40 miles roundtrip). It''s best to drive this in the late afternoon so you can see the lava in the daytime and the lava after sunset. It is really important to bring one flashlight per person and to wear good shoes. There are no streetlights or park rangers out here after dark. Chain of Craters takes you to the active lava flow from Pu''u O''o. Most of the lava flows in underground lava tubes, so I would be careful when you go exploring through the lava fields. Definitely stop for a photo op at Holei Sea Arch before reaching the end of Chain of Craters Road. The park has roped off an area for the public, meaning that it''s the safest point of viewing the lava after dark. Due to the sulphuric steam plume and the chances that the lava could be thinner in areas than in others, the park advises to stick to this area. I must note that all adventure buffs, photographers, and the curious venture closer at their own risk. The trail is unmarked, so lots of time I lag behind to see where those who are more "in-the-know" are going. If you are lucky enough to see the flow, it is quite a memorable sight. At times the lava flows are strong, but other times you may just see it dribbling into the water. No one can predict the volcanoes temperament. Remember, when the sun goes down, it is pitch black and footing can be quite difficult (seeing that you are 1-2 miles from your car).
3) On the second day I highly recommend taking any of a number of hikes. The Kilauea Iki Trail is fairly easy with a number of switchbacks through a rainforested area. Start the hike at Kilaeua Crater Overlook and follow the signs counter-clockwise. You will end up walking along a faint train in the center of the crater. Small steam vents are present throughout the flat portion of this hike on the crater floor.
4) After leaving the park you can try to catch a glimpse of the lava flow from the eastern end of Hwy. 137. Flows from 1980-90s covered what was once a black sand beach and a few homes out here. Again, this involves quite a bit of walking on lava. Enroute you pass a natural lava swimming pool and the Kapoho tidepools.
