Klaus in a tunnel

On this picture you have Klaus in a tunnel...we were alone and we can take our time...

The entrance is not easy to found but after you have a small rope (on the left of the picture ) to be sure to found the exit...

I like the sun rays through the ceiling.

The first half hour at 18 m or so and the end of the dive between 8 and 6 m ...all this dive was 73 mn...
