300 km east of Almaty — three alpine lakes inside a national park, often called the "Pearls of the Tian Shan"
Kolsai Lakes are a chain of three alpine lakes on the northern slope of the Tian Shan: Lower (1,818 m), Middle (2,252 m), and Upper Kolsai (2,850 m). They line up along the Kolsai River for 12 km, climbing the mountain in giant steps.
The name describes the place literally: "köl" in Kazakh means "lake," "say" means "gorge." Kolsai is "lakes in a gorge." All three sit between steep slopes, and the most beautiful views can only be reached on foot or by horse.
The lakes are inside the 161,045-hectare Kolsai Lakes National Park, established on 7 February 2007 by Government Resolution No. 88. The park borders Kyrgyzstan; about 72% of its area is under strict protection, with only 13% open to tourists.
Kolsai isn't a single attraction — it's three completely different lakes at three different elevations. You can't see them all in one day.
The most accessible and most-visited lake — the only one you can reach by car. About 1 km long and 80 m deep. The shore has a wooden boardwalk, cafes, and boat / catamaran rentals (~5,000 KZT per 30 min). There's a fishing pier — the lake is stocked yearly with rainbow trout.
The most beautiful and quietest of the three. Elevation 2,252 m, depth around 50 m. It's an 8 km hike from Lower Kolsai, with 450–600 m of climb: 3–4 hours up, 1.5–2 hours down. The trail winds through dense spruce forest, crosses streams on wooden bridges, and gets slippery in places. Most tourists never make it — so you can sit here for an hour without hearing another voice.
Elevation 2,850 m — above the tree line, in the alpine zone. Another 6 km from Middle on a stony, often wet trail. Don't attempt without preparation. This is the Kazakh-Kyrgyz border zone — you need a Pogranservice permit (apply 2–4 weeks ahead in Almaty). Without it, the hike ends at Middle Kolsai.
The lakes are framed by the Tian Shan's signature Picea schrenkiana spruce. In June, alpine meadows fill with wild iris — deep purple flowers in bright green grass. You'll also find Ili barberry, edelweiss, and wild apricot. With luck you'll spot a Tian Shan brown bear in the raspberry thickets, or marmots whistling on the slopes.
A forested Lower lake, alpine meadows around Middle, an above-cloud Upper — three completely different places in one day.
The trail to Middle Kolsai isn't technical, but at the end you're looking at one of the most beautiful mountain lakes in Central Asia.
Charyn Canyon, Lake Kaindy, and Kolsai are three classic stops that fit naturally into one 2–3 day route.
June for flowers and green, September for golden autumn, winter for ice and snow. Whenever you go, you see your own Kolsai.

Real reviews from TripAdvisor — pulled from the Lower and Upper Kolsai pages.
«We had a fantastic day at this wonderful lake. Highly recommend this place even without hiking — just sitting by the water is enough.»
«Please do the boat ride also — it's the cherry on top of the whole experience. The view from the middle of the lake is stunning.»
«Incredibly beautiful lake, mountains and nature in general. Honestly, the only downsides are the dirty toilets and garbage you see along the way.»
«The play of colours between the water and the mountains is quite stunning. Boat rides are available — well worth it for the perspective.»
«Surrounded by the still and lush green landscape, I couldn't help but immerse in nature's calmness. A real escape from city noise.»
«Absolutely worth it for the views, the tranquility and the connection to nature. The hike to Upper Kolsai is no joke, but the lake is unreal.»

The lakes formed from natural dams. Earthquakes — frequent in the Tian Shan — sent landslides crashing down the slopes and blocked the Kolsai River channel. Most of the area's lakes formed this way; Lower Kolsai and neighboring Lake Kaindy are tied to events between 1887 and 1911.
The Northern Tian Shan is a relatively young range: its modern uplift began in the Cenozoic (~25 million years ago), though the basement rocks are far older — Paleozoic. Kolsai sits on the southeastern edge of the Trans-Ili Alatau, just 10 km from the Kyrgyz border.
The Kemin earthquake of 3 January 1911, magnitude ~8.0, killed 452 people in Verny (modern Almaty) and destroyed over 770 buildings. Surface ruptures stretched 200 km. The same seismic event triggered the landslide that created Lake Kaindy and shaped today's Kolsai cascade.
The park's biodiversity is striking: 50 mammal species, 197 bird species, 704 plant species (12 rare). Flagship species include snow leopard (Panthera uncia), Tian Shan brown bear, Turkestan lynx, ibex, argali, and marmot. The forest is dominated by Schrenk's spruce (Picea schrenkiana), with apricot, barberry, edelweiss, and hawthorn around the edges.
Kolsai is open year-round, but the seasons are dramatically different. Weather and crowds change a lot from month to month.
About 4–6 hours one-way (~300 km). Route: Kuljinsky highway A351 → Chilik → Kegen → Saty village → Lower Kolsai. Paved all the way to the lake since 2018; a sedan handles it.
Technically yes, but even in August the water stays at 6–10°C — most visitors only wade. There is no designated swimming area.
Yes — Upper Kolsai sits inside the Kazakh-Kyrgyz border zone. Apply 2–4 weeks ahead through Pogranservice in Almaty or via a tour operator. Without it your hike ends at Middle Kolsai.
~8 km one-way, 450–600 m elevation gain, 3–4 hours up and 1.5–2 hours down. Forest trail with muddy, slippery sections — proper hiking shoes essential.
Most experienced hikers say yes. Middle Kolsai is deeper, bluer, framed by steep spruce slopes and snow peaks, with a fraction of the crowds. Lower is more striking right from the parking lot; Middle is the wilderness reward.
Yes — the classic 2–3 day route. Day 1: Charyn Canyon, overnight in Saty. Day 2: Kaindy in the morning + Lower Kolsai in the afternoon, drive back to Almaty. Add a day for the Middle Kolsai hike. UvU runs it end-to-end.
Stocked rainbow trout. Paid fishing tickets are sold at Lower Kolsai; bring your own gear or rent on-site.
Family guesthouses: Zhyldyz, Mariya, Elmira (CBT), Saty Guest House, Kolsai Guesthouse. Typically 20,000–30,000 KZT/person/night including dinner and breakfast. Book ahead in summer and on weekends.
Mid-September to early October. Note: there is no larch here — Schrenk spruce stays green. Autumn gold comes from birch, aspen, rowan, and grasses around the spruce. The reward: quiet, crisp air, and perfect skies for photography.
Weak Kcell/Beeline at Lower Kolsai (usually 3G); none at Middle or Upper. Saty has basic coverage. Download an offline map before you go.
Around 845–1,000 KZT per person (2024–2026), plus a small vehicle fee. Tent ~750 KZT. Paid at the park checkpoint — no online booking.
Typically mid-to-late April. Middle and Upper Kolsai hold ice into late May, sometimes early June.
Yes — Lower Kolsai has a flat shore promenade and rowboats (~5,000 KZT for 30 min). The hike up to Middle Kolsai is realistic for kids 8–10+ in decent shape.
Yes — Kaspi Pay, transfer, card, or cash. 30% deposit to lock in the date, balance on the day of the trip.
14–16 hours door-to-door: 5 hr drive, 4–5 hr at the lake (with boat and walk), 5 hr back. Doable but exhausting — much better with an overnight in Saty.
