Location of T'bilisi

level (1246–1968 ft) and has the shape of an amphitheatre surrounded by mountains on three sides. To the north, Tbilisi is bounded by the Saguramo Range, to the east and south-east by the Iori Plain, to the south and west by various endings (sub-ranges) of the Trialeti Range.

The relief of Tbilisi is complex. The part of the city which lies on the left bank of the Mt'k'vari (Kura) River extends for more than 30 km (19 mi) from the Avchala District to River Lochini. The part of the city which lies on the right side of the Mt'k'vari River on the other hand is built along the foothills of the Trialeti Range, the slopes of which in many cases descend all the way to the edges of the river Mt'k'vari. The mountains, therefore, are a significant barrier to urban development on the right bank of the Mt'k'vari River. This type of a geographic environment creates pockets of very densely developed areas while other parts of the city are left undeveloped due to the complex topographic relief.

To the north of the city, there is a large reservoir (commonly known as the Tbilisi Sea) fed by irrigation canals
