Chaka, the
mirror of the sky

A few centimetres of water over a thick salt crust turn the ground into a mirror. At dawn, before the coaches arrive, Chaka reflects the sky so exactly that the horizon disappears.

Chaka Salt Lake sits at 3,059 m in Ulan county, Haixi, on the third day of the Grand Route and a short drive west of Qinghai Lake. The lake is a shallow sheet of water lying on a hard salt crust, and when the wind drops, the surface turns into a mirror that doubles the sky. The water is genuinely thin: only a few centimetres lie over the hard salt below, which is what makes the reflections possible at all.

The effect depends on the water levels that season: too much water and the reflections blur, too little and the crust shows through. This is why we go at dawn, before the coaches arrive and while the air is still. For the rest of the day the lake is a working salt flat, with a small tourist train running across it and shoes that come back white with salt.

What to see

The mirror of the sky

A thin film of water over a salt crust turns the ground into a mirror that doubles the sky and the clouds.

Dawn, before the coaches

The lake is at its calmest and quietest at first light. We arrive early and leave as the tour buses pull in.

The salt train ride

A small tourist train runs across the salt flat, a short ride over the crust to the far platforms.

Working salt flats

Chaka is still a working salt lake. You walk on the crust, past piles and channels cut for the harvest.

Boots and reflections

The classic photograph is a lone figure standing in shallow water. Rented boots keep your shoes and socks dry.

High plateau light

At 3,059 m the light is hard and clear. Sunrises come late and the colours stay soft for the first hour.

Getting there and the dawn start

Chaka is a short drive west of Qinghai Lake, and the day is built around an early arrival. We leave before first light so that you are standing on the salt when the sky begins to colour. By mid-morning the coaches arrive, the wind picks up and the mirror breaks; the difference between the two hours is the whole reason for the early start.

Leave the lake hotel before dawn.
Arrive as the first light reaches the water.
Walk out onto the crust for the reflections.
Leave mid-morning as the coaches arrive.

When the mirror works

The mirror is not guaranteed. It needs still air and the right depth of water over the salt, and both change through the season. Some mornings are perfect glass, others are rippled and dull. We check the conditions and time the visit accordingly, but the lake always has the final say.

Still air: even a light breeze breaks the reflection.
The right water level: too deep and the mirror blurs.
Early light: soft colours and fewer people.
Off-season: fewer coaches, but colder and shorter days.

Practical notes for the visit

The salt is hard but uneven, and the crust around the water can be soft. Rented boots are worth it, and so is a warm layer, because the plateau at 3,059 m is cold before sunrise even in midsummer. From here the afternoon drive continues west to the emerald lakes of Dachaidan.

Practical tips:

Arrive at dawn: by mid-morning the coaches arrive and the wind ruffles the water.
Rent the boots at the entrance; the salt crust will ruin ordinary shoes.
The mirror depends on the season's water level, so we check conditions before the early start.
The plateau is cold before sunrise at 3,059 m, so bring a warm layer and a hat.

Frequently asked questions

What time is best at Chaka Salt Lake?

Dawn. The water is still, the light is soft and the coaches have not yet arrived. It is also the coldest part of the day, so bring a warm layer and something for your head.

Does the mirror effect always work?

No. It depends on water levels that change with the season and on there being little to no wind. We plan the early start, but the lake decides on the day.

How long do I need at Chaka?

About two hours is enough for the mirror and the train. We leave mid-morning and drive on to Dachaidan in the afternoon.
