The maze. A small system of tunnels where it is easy to walk and find out that you come to a place where you have been before. However, if you go to the right place, you will get into a small room (-560|66|378), from where you can dig yourself down into a great cave system.
Note that at (-589|60|269) there is an underwater entrance to the cave.

Congratulations! You found the way to a simply MIND-BLOWING-HUGE cave system where you can find waterfalls, lavafalls, lavalakes, iron, gold redstone, npc mines, and so much more. You should really worry about never finding out again.

Really big rooms really far underground are really rare. Nevertheless, here is a cute one.
