For me, the monasteries in Meteora are one of the most spectacular places in the world ...it is beautiful and has really spectacular views. There are seven monasteries nestled around the mountains, most of them with monks but a few with nuns. At first, the monasteries were only accessible by ropes that the monks raised and lowered. I asked a monk how often they changed the ropes and the answer we received was "whenever the Lord wants," an answer that wasn't entirely reassuring! If you go there, it's best to spend the night in the village of Meteora since there are many places to sleep. If you're in a rental car, you can visit all the monasteries in one trip.
