HydrangeasIn the mountains of Styria, near the village of Tragöß, there is a place that looks like an ordinary park with lawns, benches and trees for half the year, then turns into a clear emerald lake in spring. Here is how the Green Lake works, why diving is not allowed and when to visit.
Fresh flowers delivered: spray roses and flower baskets.

Why the park goes under water
The lake lies at the foot of the Hochschwab massif. In winter it is small and shallow, just a metre or two deep. In spring, snow melts in the mountains, meltwater pours into the basin and the level rises to about 10–12 metres. Paths, footbridges, benches and trees end up under water. The water is very cold and clear, and its green colour comes from the reflected slopes and underwater plants.
Why diving is banned
In the 2000s, photos of the underwater park went around the world and divers flocked to the lake. The crowds began to threaten the fragile ecosystem and water quality, so since 2016 swimming and diving in Grüner See have been banned. You can admire the lake from the shore and the trails around it.
When to go
The best time is late May and June, when the water is highest. In summer and autumn the level drops and the lake shrinks again, but then you can walk the very paths that lay on the lakebed in spring.
For trees that grow right in water, see bald cypress; for other natural wonders with flowers, Lake Tekapo lupins and Mainau island.
