Tsalka (formerly Dashbashi) Canyon is a spectacular 7-kilometer gorge carved by the Ktsia-Khrami River through volcanic basalt.
Historically a significant religious and royal center of the Trialeti region, it has evolved from a Bronze Age settlement into a major eco-tourism hub featuring the renowned 240-meter glass "Diamond Bridge".
The area has a history dating back to the Bronze Age, as evidenced by archaeological sites like the St. Ilia Cyclopean settlement. The village of Dashbashi (historically called Akhalkalaki) was once the royal seat of Trialeti dukes and the rulers of Sabaratiano.
The German settlement in the Tsalka and wider Trialeti region began in 1857 with the founding of Alexandershilf (now the town of Trialeti). Swabian German Protestants, fleeing religious persecution and the economic aftermath of the Napoleonic Wars, migrated to the South Caucasus with the permission of Russian Emperor Alexander I.
German colonists established the settlement just a few kilometers upstream from the Tsalka Canyon area. They introduced advanced agricultural practices, dairy production, and European-style architecture.
The community built the Trialeti Evangelical-Lutheran Church, featuring distinct German stone craftsmanship and a classic bell tower.
The Soviet regime banned religious worship, heavily damaging the interior of the church. The town was renamed Rosenberg in 1921 and Molotov in 1941.
Following the Nazi invasion of the USSR, Joseph Stalin ordered the brutal deportation of Caucasus Germans to Central Asia and Siberia. Ethnic Georgians from other regions were subsequently resettled in their empty homes.
During the 19th century, the Tsalka area saw an influx of Caucasus Greeks immigrating from the Kars region of Turkey. By the 1980s, they made up the vast majority of the population in the Tsalka municipality.
Following World War II, the Soviet government built the massive Tsalka Reservoir (now the largest in Georgia) to supply electricity to the region.
The site is world-famous for its striking emerald waterfalls and the massive, high-altitude Diamond Glass Bridge.
Firstly, we walked over a 240 m long sky bridge that is hanged on the top of 280 m deep canyon. Here there are options for a bicycle ride over the canyon and a swing that are one in the lifetime experiences. We do neither, it was great to walk the bridge, stop at the bar in the middle of the diamond. It was incredibly hot. I think they must fix the aircon as the rubber connecting the glass can melt.
Afterwards we walked 1.8 km down to the canyon where we got close to the waterfall over the cliff.
The spot is cool and relaxing, but coming back to the visitor center isn’t that easy. We hike up to the parking and we drive back to Tbilisi. The tour finished around 18:00 in Tbilisi airport. Just boarded the flight to Istanbul.
