This is the volcano we climbed in Stromboli, Italy. It took us about 8 hours. We literally thought we we're gonna die! Our flashlights died and we were fumbling around... By going to this link you can take a virtual hike up stomboli, it also has some pretty amazing shots of the village and of the erruptions!
As we climbed we kept running into sink holes of ash. If you stepped in ash you would slide down about 20 feet at a time.
This is what the volcano looks like in daylight. It felt like waking up on the moon.
