We drove along the Georgian Military Highway in July and stopped at Kazbek. The mountains are massive, the peak is covered in snow, and the green slopes below — it looks like a postcard. We hiked up to Gergeti Church, and the views from there are the best on the whole road. The climb on foot takes about an hour, and it's windy and chilly at the top even in summer, so a jacket is a must. It gets crowded, but it's worth it. If you're driving this road, definitely make a stop — you won't regret it.
