We had a great time and liked the tour a lot.
Originally we booked a tour to the summit, but because of the activity of the volcano and many eruptions this was not allowed. They offered us an alternative via WhatsApp which we booked. It was a tour on the north side to the area of the 2002 eruptions.
Our guide Vincenzo was great, very experienced and we learned a lot about the Etna. The tour took about 5 hours and included a jeep drive up to 2.800 meters. From there we walked along different craters back to our parked car.
The tour included 13 people and Vincenzo did it bilingual in french an English.
We would definitely recommend the tour.
It is necessary to bring a good jacket, because it is very windy at some points.
We made the tour in our runnings shoes, which was okay, but hiking boots would be better. They offered us boots as well, but we decided for our own shoes :)
Thanks a lot to Vincenzo, he made the tour a great experience!
