Volcanoes are dangerous. Even when they aren't hurling rocks, ash and lava at you, they can release potential toxic gases, crumble beneath your feet or send slurries down their slopes to wipe you away. When you hike on a volcano, you need to be aware of that risk. I'm not saying you shouldn't visit volcanic places -- you should because they are some of the most amazing landscapes on Earth! However, satiating your desire for risk needs to be balanced with not become another death on a volcano.
