Mind blowing! A real eye opener (pun intended)! You come out and all you're thinking is how thankful you are and how grateful you have to be from the fact that you can see. You go in there for about an hour in pitch black rooms which your eyes never adjust to (they only adjust if there's a bit of light coming through). The guide is blind and directs you around his world. You keep one hand on the wall and one hand in front of you as you move along. At the end of the tour you end up in a snack room where you can buy snacks and drinks with only small bills or coins (they can give you change by the front counter before entering the tour). Then you sit down with the guide and he shares his story with you and is open to any questions. Really nice guide! Amazing experience! Wow still can't get over it! You walk out a different person! Should've done it earlier in life. Btw book tickets a few months/weeks before cuz they're always fully booked.
