Most important thing you should do in Kazbegi is to visit Gergeti Trinity Church. Built in 14th century, this church is located on 1,800 meters above sea level (5,905 feet). If you are well prepared and have time, you can walk, but it will take up to 2 hours. Other options are renting a horse or a taxi. Horse ride will cost 22 USD. It’s a memorable experience, but the ride will not be easy. Taxi, usually a Niva mark of car manufactured in the Soviet Union and the ride also costs about 22 USD. If it is you first time in a Soviet car, let us warn you that this won’t be much easier than taking a horse. Don’t hesitate to bargain with drivers, because they might try to charge you more than locals.
What else? Gveleti Waterfall and the ruins of fortress located in only 9 km (5.6 miles) from Kazbegi. You can rent a taxi on the main square in Kazbegi, but note that you should walk the last several hundred meters and the route is not that easy.
Another note to consider is the chilly weather. Average temperature in summer ranges from +13 to +26 C (55 to 75 F). Winter can be really cold and full of snow. Roads are frequently blocked due to high snow in December-January.
