Visits
to the summit of Etna can be very dangerous. This is not
only so when eruptions occur at or near the summit. Etna is a surprisingly
large mountain where people can easily lose orientation, and this huge
mountain creates its own microclimate. Even when there are generally stable
weather conditions in Sicily, Etna may be shrouded in dense clouds, and
often these produce downpours and thunderstorms. Since
1999, four people were killed by lightning in the higher areas of Etna.
Nonetheless, many feel attracted by the frequent eruptive activity and
go, often alone, during unstable weather, and not well equipped for that
kind of excursion. Apart from the risk these people face (of getting lost
in bad weather and/or injured by the volcanic activity or by falling rock
fragments), there are some unpleasant insurance problems and a general
bad taste such incidents leave to those involved. So it is recommended
to everybody who intends to visit Etna: And please keep in mind the following: Etna is an active volcano. This means, there may be fragments of rock falling near to erupting vents and staying in their range is very dangerous. People who are lacking experience risk to react in the wrong manner, thus increasing the probability to get hurt, even simply by falling in an area where running is not the best idea. Even when in a certain moment there is no visible eruptive activity, the risk of very sudden and violent vent-clearing explosions (such as those which killed nine people in 1979 and two in 1987) exists. Summit eruptions often consist of so-called paroxysmal eruptive episodes, which may occur at all four summit craters. These events are unbelievably violent and many begin quite abruptly. There have been numerous occasions when areas frequently visited by hikers and tourists were showered with incandescent bombs up to 0.5 m across, and more than once people observing the activity from there had to run for their lives to find shelter from the surprising rain of such large projectiles. If there is cloud cover this will also prevent anyone from seeing what activity is going on and where fragments of lava are falling. Etna has a much more complex morphology than may appear when it is seen from some distance. It is very easy to COMPLETELY lose orientation rapidly once clouds have veiled the area you're in (this has occurred even to people who know the mountain very well), and there are areas where it's best to have very good visibility (like the near-vertical boundaries of Valle del Bove). So if you want to visit Etna, check the local weather forecasts (among which the satellite images have proved to be most reliable) and contact the mountain guides (generally, during the tourist season, you will find them at the base station of the cable car on the southern flank, and at Piano Provenzana on the northern flank). If you decide to go to the summit area without a guide, leave word that and where you are going, and when you intend to be back. Don't absolutely go up the mountain when there is the least bit of a risk of thunderstorms - lightning might strike even at much lower altitude than the summit itself! If possible, bring a field compass with you - even though this might not indicate the true (magnetic) north because of the magnetization of the lava flows. A hand-held GPS will surely work well. Cell phones may be highly precious devices in emergency situations on Etna, but be aware that there are areas on the mountain where there is no signal. Do also carry suitable clothes (including serious hiking boots), torches (with a set of fresh batteries) and enough water and food (chocolate is very efficient once you run out of power). If you respect these rules, a visit to Etna's summit area (outside the restricted area) will not be more dangerous than riding the car in your home town. How to go to the summit area? The two access routes on the northern and southern flanks have been partially destroyed by the 2002 eruption. On both flanks the eruptive vents have opened across the access routes, and those on the southern flank are still active. The lower portions of the access routes have been in places buried by lava flows. Any ascent would be possible only across terrain without footpaths, some areas being densely vegetated and others covered with young lava flows that are highly unpleasant to walk on. These are conditions where one very easily gets lost and may end up in serious trouble, including the risk of being charged for entering in restricted area. As long as the current eruption continues, it is unlikely that access to the upper part of Etna will be permitted. Once this eruption ends, it will probably take some time until regular guided excursions will be resumed.
