Mount Etna, Sicily, during quiet time —
A view from 2,800 meters up the mountain, looking toward the peak of Mount Etna. The top of the volcano is actually a series of craters. Because it erupts frequently, Etna's landscape is constantly changing. These images were taken just a few days before the most recent eruption on October 26, 2013.

Desolation —
The surface of the volcano is stark, barren ... and stunning.

There is life —
Rock piles are evidence of life -- of previous visitors.

She's hot —
Although steam flows from vents and craters, the main visitor area doesn't have the unpleasant sulfur smell often associated with volcanoes.

Tour party —
It's possible to hike up Etna. But guided trips to the ridge of the crater -- which include cable car, 4x4 bus and a short guided walk -- take about two hours total.

Etna crater —
Etna is Europe's tallest and most active volcano. Rather than a single crater, its peak has several. Some spots are more active than others.

One of Sicily's top attractions —
The volcano is open to visitors every day and closes only during dangerous eruptions.

Easy way up —
Visitors can take a cable car to about 2,800 meters up the mountain and transfer to 4x4 vehicles.

Life on Mars? —
The view toward Catania is a reminder that civilization isn't too far away.
