Entry & Exit
Use stone stairs vis-a-vis eastern part of the parking area, then go to water through the stones. Alternatively, you can enter on the beach area (in summer season, using it for divers is not allowed until 20:00).


Underwater profile
Big plateau with a lot of aquatic plants up to 10 meters, full of fishes in summer and toad mating grounds in spring. Ideal for beginner divers.
Big boulders from 20 to 40-60 meters, in big parts covered by mud and looking like stone walls, they form a complex underwater landscape that might be tricky to navigate - always set up your compass!
On the most eastern boulder, in the 43 meters deep, you can find a small stalactite. It’s easy to miss, especially when water clarity is limited.

Artificial attractions
Divers place a lot of artificial objects under water to make diving more attractive. In Underwilen, you have a small statue direct by the parking entry, tribal masks left from entry, and music instruments in about 20 meters deep.
