Known as Tana Ravine from the 4th to 7th centuries, the Ateni Valley was a densely populated place with a major road that passed through it.
The Ateni Valley is especially notable for the diversity of its waterways. The Tana River flows through the villages of the valley, eventually joining the Mtkvari River.
A highlight of any visit to the valley is the Biisi Waterfall, which can be reached by a 2,5 km long hiking trail, which goes through beautiful nature and is a great choice for a half-day outdoor activity. The site is often visited in winter as well when the waterfall transforms into a beautiful ice pillar.
In addition to these natural wonders, the Ateni Valley is also outstanding for its abundance of architectural monuments, including Ateni Sioni, Ateni Fortress, Tsero Church Complex and Ateni Convent.
