Beach lakes in Kazakhstan: which lake suits a summer swim

The beach lakes of Kazakhstan fall into three groups: Kapshagay and Balkhash in the south-east, the pine-ringed Kokshetau and Bayanaul lakes in the north, and the big reservoirs of East Kazakhstan. For a visitor based in Almaty, Kapshagay is the only one that works as a day trip; most of the others are weekend trips from Astana, Pavlodar or Oskemen. Almost all of them are lakes for June to August.

Kapshagay is the practical choice from Almaty

If you are in Almaty and want to swim, Kapshagay Reservoir is the realistic option. It lies about 80 km from the city on the A3 highway, a drive of 50–60 minutes on weekdays, and the summer water is 22–28 °C. Swimming opens on 1 June.

The reservoir covers 1,847 km² on the Ili River. The town on its shore was renamed from Kapshagay to Konaev on 3 May 2022, so you will see both names on maps and signs.

The mountain lakes closer to Almaty are not beach lakes. Big Almaty Lake bans swimming because it supplies the city’s drinking water, and the road has been closed to private cars since 2020 and to motorcycles and electric transport since 30 April 2026, so you walk. Kaindy Lake stays at around +6 °C in summer. For those, see nature near Almaty and plan them as walks, not swims.

The lakes compared at a glance

The table sets the main beach lakes side by side. Distances are straight-line figures from the nearest large city unless marked as road, so the actual drive will be longer.

Outside Kapshagay, each lake is a trip from a base city in its region. Choose the region first, then the lake.

The northern pine lakes suit a slow summer stay

The Kokshetau and Burabay lakes in the north are pine-ringed summer lakes, set among low pine and birch hills. Astana is the gateway, with Kokshetau closer still.

Lake Zerenda is small and freshwater, with sandy beaches and pine woods, about 44 km in a straight line from Kokshetau. It is getting shallower, with a maximum depth of 6.8 m, which is worth knowing before picking a month. Lake Shchuchye sits on the edge of the town of Shchuchinsk and is the deepest of the Kokshetau lakes. Its maximum depth is given as anywhere between 31 and 40 m, depending on the source. Bolshoye Chebachye, the largest lake of the Burabay group, has granite shores, islands and depth of about 33 m.

Lake Shalkar is long, shallow and slightly salty, with steep wooded banks on the south side and resorts along the shore. It is a place to stay for several days rather than a detour.

Bayanaul gives clear water among granite ridges

In Bayanaul National Park, north-east Kazakhstan, the lakes sit inside granite hills. Pavlodar is the nearest large city, about 180–190 km in a straight line.

Lake Zhasybay is the main beach lake here: 3.5 by 2.4 km, up to 14.7 m deep and known for clear water. It is popular with visitors from central and northern Kazakhstan, and a long detour for anyone else. Lake Toraigyr is smaller at 0.88 km² and 3.1 m deep, with two rocky islets called Zhartas and a village on its shore. It fits best as part of a wider Bayanaul trip.

Balkhash and the eastern reservoirs are for long trips

These are the big waters, and the distance is the main cost. Lake Balkhash is a crescent about 600 km long, about 400 km in a straight line from Almaty. Its western half is nearly fresh and cloudy, the eastern half salty and bluish. The average depth is only 5.8 m, and the lake is frozen from November to early April.

In East Kazakhstan, the Bukhtarma Reservoir is a dammed stretch of the Irtysh between mountain ridges. Figures for its area disagree: one version gives 5,490 km², another up to 5,940 km². Either way it is the largest reservoir in the country, about 146 km in a straight line from Oskemen, with a 1,316 m bridge open since 2024. The reservoir absorbed Lake Zaysan, which lies further east in a high basin between the Altai and Tarbagatai ranges. Zaysan is huge, shallow and reed-fringed, frozen from November to late April, and far from any usual tourist route.

When the water is open

The swimming season is short and nearly the same across the country: June to August is the best window at every lake in this collection. September is a reasonable fallback, but most lakes drop to “possible” by October.

For a beach trip, aim for July or August. If you only have June, the south-east lakes and Burabay are already in their best months.

Searches for these lakes peak in July; the study of summer demand shows it month by month.

Lakes that look like beaches but are not

Several well-known lakes appear in searches for swimming but suit other plans. Big Almaty Lake bans swimming. Kaindy Lake, with spruce trunks rising from the water, stays around +6 °C in summer.

Kobeituz near Ereymentau, about 158 km in a straight line from Astana, can turn pink from an alga in warm months. It is about 20 cm deep, with salt at 334 g/l and no facilities on the shore, so it is a sight, not a swim. For warm water outside summer, Rakhmanov Springs in Katon-Karagay National Park have thermal radon water at +32–42 °C, but they lie 111 km beyond Katon-Karagay village in a border district.
