There is a mashrutka (mini bus) which operates daily, costs only GEL10. You can take this public transportation in DIDUBE metro station. You can take the same bus on the way back from kazbegi to tbilisi. Again, depends on how you travel and how many of you in a group or solo traveller.

We went on end of March/ beginning of April. General weather was not so called but in the mountains the weather was cold with snow as well. Snow was somewhat melting in some areas but most of the mountain area were covered by snow. I liked that weather and there were lot of people who were doing hiking that time as well. So I suggest April.

If you are in UAE, I booked through Musafir travel agent. However I have the contact details of the tour guide of ours from there, who was a very nice guys and most importantly he speak very good English. So if you want I can give you his contact details.

Yes there are places around Meteo station with cell coverage (half way to toilets )

Местные на внедорожниках стоят прямо в центре Городка Степанцминда. Их там много. Сколько стоит там под'ем к Гергети не знаю, так как бралиндивидуальный тур в Тбилиси, мне он стоил 80 долларов

HI , Nithin ill tell you just one thing that hiking in mount kazbeg with kids is not possible, it needs power and long time walking also good equipment for hiking. best regards Alex Nadibaidze
