Head north from Tbilisi along the Georgian Military Highway, the only road connecting Georgia to Russia through the high Caucasus Mountains. First you'll visit Zhinvali Dam, a hydroelectric dam on the Aragvi River. Despite its artificial origins, the reservoir blends in with the surrounding environment perfectly and delights visitors with its turquoise waters. As you descend to the shores of the reservoir you will notice the ruins of a church from a settlement that was relocated out of the flooding area of the dam.   Next, visit Ananuri Fortress, known for its stunning panoramic views. It was built by the Dukes of Aragvi and its earliest parts date back to the 13th century. After this, you'll explore Gudauri, a ski resort located in the Greater Caucasus Mountain Range. The slopes of Gudauri are completely above the tree line. Discover the Treaty of Georgievsk Monument, built in 1983 to celebrate the bicentennial of the Treaty of Georgievsk and ongoing friendship between Georgia and Russia. Inside the monument is a large tile mural that spans the whole circumference of the structure and depicts scenes from Georgian history. Finally, you'll visit Gergeti Trinity Church. The church is located under Mount Kazbek, and served as a popular waypoint for travellers on the road connecting Russia and Georgia. At the end of the day, return to Tbilisi.
