National Botanical Garden of Georgia: Tbilisi's Hidden Valley

The National Botanical Garden fills a deep gorge immediately behind the Old Town of Tbilisi, capital of Georgia (the country in the South Caucasus). Its main entrance is tucked below the Narikala Fortress walls, and its terrain runs southward through a valley that most visitors to Tbilisi never discover — despite it being a few minutes' walk from the sulfur baths and the cable-car station. That near-invisibility is part of what makes it one of the more rewarding places in the city: a genuinely green, quiet valley that opens up unexpectedly out of the dense fabric of the historic district, a complete change of pace from the stone and cobblestone of the Old Town streets above.

What is the National Botanical Garden of Georgia?

The National Botanical Garden of Georgia (formerly the Tbilisi Botanical Garden) is a large historic garden filling the Tsavkisistsqali (Leghvtakhevi) gorge directly below the Narikala Fortress, behind Tbilisi's Old Town. Its origins go back to a royal garden in this valley in the early 17th century; it was formally established as the Tiflis Botanical Garden in 1845, under Russian administration, and has grown ever since into a collection of over 4,500 plant species from Georgia, the Caucasus, and around the world, spread across some 161 hectares of valley and hillside. The valley carries a stream that feeds ponds and drops over the Leghvtakhevi waterfall at its upper end, and the enclosed, wooded gorge stays noticeably cooler than the city above. There's an entrance fee, and it can be entered from the Old Town (Abanotubani) side or from an upper gate by the Mother of Georgia statue.

A garden with a long history

There have been gardens in this valley for centuries. The garden's predecessor was a royal garden established in the early 17th century in the Tsavkisistsqali gorge — the "fortress gardens" of the Georgian kings, growing ornamental and medicinal plants, recorded by European travelers in the 1600s and 1700s. After Georgia's annexation by the Russian Empire, the garden was revived and formally established as the Tiflis Botanical Garden in 1845; it was expanded repeatedly through the 19th and 20th centuries (a plant nursery and floristics center followed later in the 1800s). Today the institution holds a collection of over 4,500 plant species from Georgia, the broader Caucasus, and regions as far afield as China, Japan, the Himalayas, North America, and the Mediterranean, across roughly 161 hectares of valley and hillside — though the part most casual visitors walk occupies a smaller central section of that total.

The garden

The character of the garden is shaped by the gorge it occupies. The valley floor carries the Tsavkisistsqali stream, which feeds a series of small ponds and reaches the Leghvtakhevi waterfall at the upper end of the accessible area; the slopes on both sides rise steeply through forest and cultivated planting to the ridgeline. The enclosed valley, the water, and the tree canopy together create a microclimate noticeably cooler and more humid than the city — which makes the garden especially welcome in the hot Tbilisi summers, when the Old Town streets above can be oppressive.

The planting is organized into sections by geography and botanical category — a Georgian flora section, a rose garden, collections of trees and shrubs from various regions, a greenhouse — though the overall feel is more of a large, pleasantly overgrown park than a rigidly scientific institution. The paths wind through the valley so that you can do either a short visit covering the main highlights or a longer wander up the slopes into quieter corners. The mature trees throughout — many large specimens built up over the garden's long history — give it a settled permanence that newer green spaces lack. (There are also pavilions, old bridges, benches, and a children's playground along the way.)

The Leghvtakhevi waterfall

The waterfall at the upper end is the garden's most dramatic natural feature and the destination most visitors are heading for. The Leghvtakhevi stream drops about 22 meters over a basalt face into a pool at the base, and the falling water, the spray, the surrounding greenery, and the gorge walls make a genuinely refreshing spot, particularly in summer. The walk to it from the main entrance is about 20–30 minutes of easy going, crossing the stream on small bridges and passing through progressively denser vegetation as the valley narrows.

The waterfall can also be reached from the Old Town side without entering through the main gate: a separate gorge path runs in from the streets near Abanotubani and reaches the falls from the lower end. (Note that this gorge walk and the garden are connected but distinct — the short Abanotubani gorge walk to the waterfall is free, while the Botanical Garden proper charges admission.)

Connections to the Old Town

The garden's position makes it a natural part of an Old Town walking day rather than a separate trip. The main entrance is a short walk from Abanotubani, and there's a second, upper entrance by the Mother of Georgia statue on the Sololaki ridge — which means you can enter from the cable-car/ridge side and walk down through the garden, or enter from the bottom and climb up. A satisfying circuit: take the cable car up to Narikala, walk the fortress walls to the Mother of Georgia, then descend into the Botanical Garden from the upper gate, work down through the valley past the waterfall, and come out at the bottom near Abanotubani — a half-day loop covering the best elevated and ground-level parts of the historic district in one continuous route.

Getting there and visiting

• Location: 1 Botanikuri Street, Old Tbilisi — the main entrance is below Narikala Fortress, near Abanotubani; a second entrance is on the Sololaki ridge by the Mother of Georgia statue.
• Getting there: On foot up Botanikuri Street from Abanotubani; or via the cable car to Narikala / the Mother of Georgia and in through the upper gate.
• Hours: Daily, approximately 09:00–19:00 (longer in summer).
• Admission: There is an entrance fee (a few lari).
• Tips: Wear comfortable shoes (the terrain is hilly and paths can be uneven); allow 1–2 hours for the valley and waterfall, more to explore the slopes; best in spring (planting) and summer (cool shade and the strongest waterfall flow).
• Combine with: Narikala, the Mother of Georgia, and the cable car (the upper-gate circuit); Abanotubani and the sulfur baths; the Leghvtakhevi gorge walk — the whole southeastern ridge-and-Old-Town cluster.
