Tbilisi Sea

Tbilisi Sea: The Urban Oasis of Georgia’s Capital

The Tbilisi Sea, officially known as the Tbilisi Reservoir, serves as a vast aquatic escape located just northeast of Georgia’s bustling capital. This immense man-made lake was created in the mid-20th century by flooding the salt lakes of Avlabari and is now an integral part of the city’s landscape and infrastructure. Encircled by rolling hills and developing recreational zones, it provides a crucial source of fresh water for Tbilisi’s residents and acts as a popular year-round recreational hub. In the summer, its shores come alive with beachgoers, water sports enthusiasts, and families seeking refuge from the city heat, making it a vital social and leisure destination. The reservoir is not only functional but also scenic, offering panoramic views of the surrounding area and a refreshing contrast to the urban environment. Its development includes parks, resorts, and even the impressive “Chronicles of Georgia” monument overlooking its waters. As a key component of Tbilisi’s geography, the reservoir supports local biodiversity and offers a unique blend of nature and city life, essential for both the ecological balance and the well-being of the capital’s inhabitants.
