Amboy Crater is a 6,000-year-old cinder cone volcano that rises above a lava field. This cinder cone is estimated to be 79,000 years old. You can hike to the rim using the western cone trail.If you're visiting Roy's Ghost town, this is a few miles down the road. There is a parking lot you can turn into with viewing deck. I loved seeing all the plants spring up from the black lava forms. New life sprouted from the darkness.
