It's an increadible experience up the Sinai, but the guides sell you this a first level dificulty climb. This is not true. And the dry weather became freeze ou too much hot very fast. It's impossible climb the mountain and see the Monatery at the same time you go there. The Monastery is too interesting but the visit gets you about 15 or 20 minutes, because the monks don't let you stay looking at. There, you keep the line, see and farewell.
