On Sunday, we checked off another item on our Bucket List - diving in Sundhäuser See.  I can't remember exactly how I found  out about this lake, although I think it was this PADI article I read about a year ago.  What caught my eye was the underwater city part.  And the fact that it was one of the closer ones to us that was listed.  We weren't going to be far from the lake so it naturally made sense to pay it a visit.
