It's sad that you had to prove yourself, but I'm glad in a way as this is another stunning shot. It must be amazing to see in person. Do they take you through on guided tours? I know visitation to this areas is limited, but I've always wondered how they stop unauthorised visits.
No, I was alone with my girlfriend. They give to you a special permit and you must attach on your bag. You need to walk with a simple map and find that place by yourself... It has been so hard under that strong sun! >_<
