At the base of the Cone you can see the trail that circles it. The coppery dunes give way to naked lava fields, and beyond them is the forest, and lakes of the Cascades. Hiking trails weave among the painted dunes. The area is littered with volcanic bombs. These are globs of lava that were tossed high in the air, and cooled into weird shapes before they hit the ground.
Wild flowers poke out from the barren cinders.
Lassen Volcanic National Park also includes Bumpass hell, and area of hot springs that you can explore on wooden walkways.
