Sarmishsay is a desert gorge about 40 kilometres north of Navoi that contains one of the largest collections of petroglyphs in Central Asia — more than 4,000 rock carvings cut into the cliffs and boulders over roughly 10,000 years. The oldest date to the Neolithic period, showing hunting scenes, animals, and human figures. Later carvings include Bronze Age symbols, Iron Age warriors, and medieval Islamic calligraphy.
The gorge is scenic in its own right: a narrow canyon through reddish sandstone, with a seasonal stream and surprising patches of vegetation. Getting there requires either a car and driver from Navoi (about an hour on rough roads) or a tour arranged through one of the guesthouses in the city. The site is not heavily visited and feels genuinely remote. Wear shoes suitable for scrambling on rock.
