Some 60km from Zugdidi via Senaki, Nokalakevi is a picturesque and historic ancient Colchian royal town and fortress. A tunnel leads down to the Tekhura River from the grassy grounds, and admission includes an interesting archaeological museum. Excavations are ongoing (see www.nokalakevi.org). About 1km upstream on the Tekhura you can take a dip in soothing thermal pools.
