Sinceramente yo no e visto, pero no hace falta 4x4 para llegar a la base. Y tampoco hay camino para travesía de ese tipo ya que es un parque y reserva

Sorry, I dont know how they do if weather is bad. But most likely you will will not have any problems with the weather. Enjoy!

Yes, the camping area you will have a perfectly good viewpoint and can see and hear its eruptions. I have seen people take horses. The only unfortunate thing is the horses aren’t well taken care of so I’m usually against that. But thats totally up to you. Hiking wouldn’t be an option though, its between a moderate and difficult trek in my opinion and definitely not short.

Is anything really safe? If you mean would this activity be performed in the U.S? Definitely not. Did I feel safe? Absolutely! But what do I know? I don’t think any tourist in a tour group has ever died from Fuego’s lava and hundreds of people go up it every day. If anything is dangerous its Pacaya. You are close enough to the lava to throw rocks at it lol. But on Acatenango your on a completely different mountain, if anything I’d imagine its safer than being down below. Don’t waste your time questioning safety. If tour are going up and your seeing hundreds of happy people coming down then its safe. I would just recommend going with a reputable tour guide and not going by yourself. Or if you do, don’t go to the very top because of extreme weather and cold. The tours stop I believe about 900 feet below the summit.

You must reserve with minimum time 15 days. especially for what you should bring with clothes or equipment and communication with your coordinator. The cost depends if you want to do private or collective tour. For December is a beautiful date. There are many companies in old Guatemala that offer the tour and various prices. But few local organizations. I recommend you to Elvin and Aprode. good luck

All the tours offered in Antigua pretty much end up to be with a 2-3 companies. I booked the tour directly with Aprode through whatapps, and we were later join at the basecamp by a much bigger group of people that booked through various agencies. We paid just a few dollars more than them, but we got a much better service/meals/sleep. I highly recommend to just contact Aprode through Whatapps and skip the middleman-agencies.
