Sissu Lake
An easy lake by Sissu village in Lahaul, a short drive through the Atal Tunnel from Manali.
Manageable with care. The biggest factor is altitude / ams: 3120 m — high altitude. Est. SpO₂ ≈ 89% arriving unacclimatised. AMS becomes common if you ascend too fast. Acclimatisation rules start here.
At 3120 m, altitude is the quiet risk. Arriving from low elevation in a single day gives your body no time to adjust — pace the climb where you can, and learn the early signs of AMS.
Score 24/100, re-derived from the site’s real characteristics — never a marketing grade. A higher number is not “don’t go”; it is “go informed.”
- mild AMS possible for those driving up quickly from Manali through the tunnel
- cold water and cold winds off the Chandra valley
- icy paths and slush in winter and early spring
- If it sits high, the thin air — not the water — is the real risk; don't race up from the plains, and learn the signs of AMS.
- Alpine water and weather turn dangerously cold fast, even in summer — carry warm layers.
- Remote shores mean slow rescue; share your plan and turn back with time to spare.
- Kullu (KUU)~67 km
- Dharamshala (Kangra) (DHM)~88 km
- Joginder Nagar~63 km
- Una Himachal~137 km
Drive to the roadhead Sissu / Keylong. From Joginder Nagar (Mandi) (~63 km) shared taxis and state buses run the last leg to Sissu Lake.
Distances are straight-line (as the crow flies), computed from the coordinates. Real road distance and driving time in the mountains are longer — confirm current road status and the last motorable point with your operator, especially in monsoon and winter.
Live from Open-Meteo at this spot, adjusted to 3,120 m. Mountain weather turns fast — treat this as a hint, not a promise.

See it in 3D
A Google-Earth-style flyby that drops in from orbit and traces the real approach trail up to Sissu Lake(where it’s mapped in OpenStreetMap), over real satellite terrain — so you can read the climb and the lie of the land before you go.
Coordinates, heights and depths are approximate, curated from public sources — good enough to plan and to gauge risk, not surveyed. The safety grade is a deterministic guide, not a guarantee; conditions change with weather, water level and crowds.
