You have to wait till the afternoon to go in for lava viewing. I know it's cool to go in the dark, but the hike to the viewing area in the dark is not easy. Bring flashlight & water, wear sturdy sneakers or hiking shoes, bring a jacket. It is a magnicient sight if you do go. They do not allow you to go in after 8 p.m. and everyone must be out by 10 p.m. This is a county run area, not a national park area. Even so, they adhear to the rules exactly, and there are no exceptions made.
