Lake Tuz

LakesAksaray,Türkiye

A knee-deep Turkish salt lake that mirrors the sky in spring, dries to walkable crust by August, and holds the country's biggest flamingo colony.

September·Edge of season

Sep–Oct

Into autumn the summer's salt stands hard, white and walkable, the season's clean crust at its best — but the flamingos are dispersing, the pink has faded, and cooler days signal the water's return.

Year-round Turkey's salt works run beside the lake all year, but the lake itself has no fixed face: shallow water in winter and spring, white crust in high summer.

Lake Tuz is a salt lake of 1,600 square kilometres on the plateau of central Türkiye, between Aksaray, Konya and Ankara, knee-deep in spring when it mirrors the sky to the horizon, dry by August to a crust of salt walked out on for kilometres, pink in its last pools before it dries, and it holds the largest colony of greater flamingos in the country on islands far out in the water. The lake has no outlet and is one of the saltiest on Earth, and for a few weeks in spring the runoff spreads a sheet of water barely deep enough to cover the feet, so that on a windless morning the whole lake turns into a mirror with no horizon, walked into barefoot from the roadside at the Aksaray end; as the summer evaporation takes hold the sheet thins away, the shrinking pools of brine flush pink and then rust-red as the microbes in them ramp up their pigment, the same Dunaliella that colours the flamingos through the shrimp they eat, and from July the salt works move onto the pans and scrape the crystallised floor into hills of raw salt, most of the salt of Türkiye. Once the water has burned off the lakebed sets into a crust thick enough to carry a truck, blinding white to the horizon. The flamingos nest on islands far out in the lake in colonies of five to six thousand nests, their most important breeding ground in the country, and from June the shallows fill with grey gangling chicks learning to feed while the adults come and go from islands too far to reach, watched from the shore with binoculars; a drought in 2021 dried the lake early and killed thousands of chicks before they could fly. More than a kilometre under the lakebed fresh water is pumped into the ancient salt to melt out caverns that are then filled with natural gas, the country's gas store. Lake Tuz is a lake that is a mirror in spring and a floor in summer, and the flamingos time their year by it.

Worth knowing

Good to know

Come at first light for the mirror — the wind that ruffles the water usually drops overnight and picks up by mid-morning, and the midday glare off white salt flattens everything you photograph.
Walk a few hundred metres out before you stop — the salt nearest the car parks is churned into grey slush by tyres and footprints, and the clean, unbroken white only starts further in.
Watch the flamingos from the shore with binoculars — the nesting islands lie far out in the middle of the lake, and walking towards a colony can push the adults off their chicks.
Wear closed shoes rather than bare feet — the crust is sharp enough to open skin and it hides soft brine pockets underneath. Rinse your shoes and your car afterwards, because salt corrodes both.
Use the Şereflikoçhisar side — the Ankara–Aksaray highway runs along the eastern shore with pull-offs that put you straight onto the salt, while the western shore has almost no made-up access.

Things to do

1
Walk onto the mirror before the lake dries
For a few weeks in spring the lake wears a sheet of water barely deep enough to cover your feet, and on a still morning it turns into a mirror that runs all the way to the horizon. Walk out far enough from the shore and the clouds are travelling beneath your boots, with no line left anywhere to tell you where the ground ends.
2
Watch Turkey's biggest flamingo nursery
From June the shallows fill with grey, gangling chicks learning to feed, while the adults come and go from nesting islands too far out to reach. Stand still on the shore and you hear the colony before you see it — a low, constant gabble carrying across water that has nothing else on it to break the sound.
3
Cross the salt crust on foot in high summer
Once the water has burned off, the lakebed sets into a crust thick enough to carry a truck, and you can walk out for kilometres on it. It crunches like packed snow, holds the day's heat in the soles of your shoes, and gives the eye nothing to fix on but the sky.
4
Catch the brine at its reddest
In the last weeks before the lake dries completely, the shrinking pools of brine flush pink and then a deep rust-red as the microbes living in them ramp up their pigment. It is not a trick of the sunset — the water is genuinely that colour, and it drains away with the first autumn rains.
5
Watch the salt lifted from the drying pans
From July the works move onto the pans and start taking up the summer's crop, scraping the crystallised floor and building it into hills of raw salt. Get close and you see the harvest as it really is: coarse, grey-white grains, still damp, that will end up on tables across the country.
