Koldor Dive Site is a southern-shore freshwater shore dive on Lake Teletskoye, opposite Yailu, where the lakebed falls away fast from the beach. The profile is simple to reach but quickly serious, so the dive is about depth discipline, clean buoyancy, and staying organized once the bottom drops off. Cold water and seasonal clarity make it a better fit for divers who want a lake wall profile and freshwater fish rather than a casual swim-around.
Conservative baseline from public research. No community dives logged yet.
Depth range, seasonality, and planning context.
Reported Depth
40m - 50m
Depth Note
A drop-off to around 40–50 m is reported about 10–15 m from the shore.
Best Season
Late spring through early autumn for easier shore conditions; winter is possible for drysuit teams when the lake is calm or frozen.
Typical Conditions
Cold freshwater, a short shore approach, and a steep drop-off very close to the entry point. Visibility varies with season, but the lake is often clear enough for structure-focused diving.
Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes
The main risk is how quickly depth builds after a short shore approach; conservative buoyancy and depth planning matter more than navigation.
Access Restrictions
Diving does not require a special permit from the Altai Nature Reserve.
Legal Notes
No special Altai Nature Reserve permit is required for diving here.
Community notes to help plan your visit.
Scuba Diving
A short shore walk leads straight into a steep freshwater drop-off. The key skills are buoyancy control, depth discipline, and staying oriented as the bottom falls away.
Freediving
Only for experienced freedivers comfortable with cold water and a quick drop-off close to shore.
Snorkeling
Not ideal for casual snorkeling because the bottom drops away quickly from the beach.
