Lake Salda

LakesBurdur,Türkiye

A turquoise lake in southwestern Türkiye whose white beaches are rock microbes are still building — the closest match on Earth to a Martian crater floor.

September·Peaking now

Jun–Sep

High summer is the whole show: the sun stands high enough to light the white floor to electric turquoise, the water warms to around 20–25°C for swimming, and the dry-month drawdown widens the pale shoals. Weekends in July and August are a scrum.

Year-round The white shore, the microbial mounds building rock, and the deep alkaline lake are here every day — but the White Islands stay closed behind their barrier, and the turquoise fires only under high sun.

Lake Salda is a turquoise lake in Burdur province, in southwestern Türkiye, ringed by beaches of white mineral that microbes are still building, the closest match on Earth to the floor of the Jezero crater on Mars, and it is swum at marked public beaches in July and August, looked at across a fence where the white islands stand, and seen whole from the black pines on the slopes above. The lake is deep, 185 metres, and fed by no river, only rain, snowmelt and springs, so its level falls in drought and with the pumping of the basin's groundwater, and its white shore is not sand but hydromagnesite, a carbonate laid down by mats of microbes in the shallows and broken into pale grains that crunch rather than slip underfoot; NASA sent scientists here before the Perseverance rover landed in 2021, because the carbonate minerals ringing the old shoreline of Jezero are the same, and Salda is the place on Earth to learn how they formed and whether they hold life. At the public beaches the water is so clear that the white floor seems to hold the light, and the turquoise runs out over the shelf to a deep bottle-green centre. The mounds that give the lake its colour, the White Islands, are off limits behind a wooden barrier since the crowds of a few summers ago began breaking them, and they are looked at rather than walked on, standing clear of the water as the lake draws down through the dry months and the shallow turquoise band widens. From the pine slopes that come down to the lake the whole shape of Salda opens, a white rim, a turquoise band where the shelf lies shallow and the green centre, and the drive around the shore passes the villages of Yeşilova and the picnic beaches. For the rest of the year Salda is a lake to look at rather than get into, cold and windswept at 1,140 metres. Lake Salda is a piece of Mars in Anatolia, and the microbes are still at work on the beach.

Worth knowing

Good to know

Come when the sun is high — the turquoise only fires when the light can reach the white floor; under cloud, or early and late in the day, the same water reads as a flat grey-blue.
Weekends in July and August are a scrum — Salda is a domestic summer favourite, so come on a weekday and come early if you want the shore quiet.
The white shore throws the sun straight back at you — glare off the pale mineral is fierce and there is almost no shade, so bring a hat, water and sunscreen.

Things to do

1
Crunch across the white mineral shore
The pale grains underfoot are not sand but broken pieces of the lake's living mounds, and they crunch rather than slip. Walk the open shore where the white shelf runs out into the water, and within a few steps the lake beside you turns from milk to turquoise.
2
Swim out over the white shelf
At the marked public beaches you can wade into water so clear that the white floor seems to hold the light. Swim a little further and the pale shelf gives way beneath you to deep green, the point where the lake begins its long drop.
3
Look across at the fenced White Islands
The mounds that give the lake its colour are now off-limits, so you stand at a wooden barrier and look. It is a strange, quiet act — staring at a beach you may not step on, because the ground there is alive and still growing.
4
Climb into the black pines above the water
From the pine slopes that come down to the lake, the whole shape of Salda opens up: a white rim, a turquoise band where the shelf lies shallow, and a deep bottle-green centre. The line between them is startlingly sharp from above.
