I'm so happy we went with Go Etna while we were in Sicily! Easy to schedule and plan a pickup. They…read morepicked us up in Catania then drove us to a gas station a little up the mountain where we discussed and departed into groups based on language. We did the half day which involved a short hike, they had number of employees who either led or hung back with people who were not physically up for it. Since Etna was actively erupting we obviously didn't get to go to the top but we did a shorter hike on the craters. Our guide was very informative and was fun to chat with. Afterwards we went to a chalet area where you could use the restroom or grab a snack. They got us back to Catania in one piece at the same pick up spot. I would definitely give them a go and schedule with them again!

Avoid the "Summit Trekking Tour" with Go-Etna. We booked the tour weeks in advance of our trip, but…read morein the days leading up to the tour it became clear that volcanic activity (and forecast weather) were going to make a summit trek impossible. Rather than offering to rebook clients on a different date/tour, the company continued as if everything were normal and responded to all of our Whatsapp messages as if there was hope that the summit trek was still happening. The one bright spot was the guide, who was knowledgable and engaging. Our "summit" tour consisted of a drive up to the Observatory and then a walk along the lower elevation slopes. This is the exact same "Etna Nord Crater Tour" offered on their website for 90 euros but we were charged 130 euros (the company refused to refund the difference). My advice: Do not book tours in advance since Go-Etna is not an honest operator and offers no flexibility. Only make a reservation 24-48 hours before and confirm that a) the volcanic conditions are low b) the weather is forecast to be good and c) Go-Etna confirms via WhatsApp that other groups have recently completed actual summit treks to 3,300 meters in recent days. If any of these conditions are not met, save your money and park at the Piano Provenzana parking lot and just do your own independent hike!
