At a depth of 18 ft (5.5 m), Bohunskyi Quarry hits a thermocline — a sharp temperature drop where warm, clear water turns icy cold. Below 33 ft (10 m), total darkness sets in from a layer of suspended sediment on the bottom, and that’s exactly where amateur divers most often find themselves in trouble they don’t have the experience to get out of. This isn’t just a scenic lake on the edge of Zhytomyr — it’s a body of water that demands respect.
The quarry formed where mineral extraction once took place in the Bohunia district, on Zhytomyr’s northern outskirts. The oval-shaped lake covers about 6 acres (2.5 ha) and measures roughly 490 by 755 ft (150 by 230 m), filled with clear spring water that holds a steady 39°F (4°C) at depth year-round.

Zhytomyr’s Favorite Beach and Most Dangerous Body of Water at Once
I think the contrast between Bohunskyi Quarry’s popularity as a city beach and its real danger at depth is exactly what makes it worth a dedicated article: most sunbathers on the shore have no idea that just a few meters beneath them starts a zone experienced divers describe total darkness in as a genuine challenge.
Spring-Fed Water Year-Round
Unlike many flooded quarries that warm through their entire depth in summer, Bohunskyi is spring-fed, holding a steady low temperature at depth regardless of season — so the water turns cold the moment you swim past the shallows, even on the hottest days.
What Not to Expect
Don’t expect warm water at every depth: the sharp thermocline at 18 ft (5.5 m) isn’t a rumor — it’s a documented feature of the lake, and swimming at depth without experience can be dangerous because of the sudden temperature shift. Diving below 33 ft (10 m) is recommended only for trained divers, given the complete lack of visibility.
What to See Nearby and How to Fit It Into a Route
- Zhytomyr city center — a few kilometers away, the oblast capital’s historic district.
- Druzhbivskyi Quarry — another turquoise quarry in Zhytomyr Oblast, further out in Korosten Raion.
- The “Stone Village” geological preserve — a natural landmark in the same region.
Practical Information
- Entry: free
- How to get there: by public transport or car to the Bohunia district in northern Zhytomyr
- Time needed: 1–3 hours
- Special conditions: don’t dive to depth without gear and experience; account for the sharp thermocline
Conclusion
Bohunskyi Quarry has a split personality: a scenic city beach on the surface, and a body of water with real risks at depth, where darkness and cold begin just a few meters from sunbathers on shore.
