Opening times vary for each monastery. But they all close at lunchtime and for one day during the week. Each charges a small entry fee, and both sexes should be modestly dressed. Women are expected to wear skirts, but you can borrow one from the selection at the entrance to pull on over your hiking clothes.
Meteora gets crowded in the summer, especially at weekends. In the winter, it can be freezing cold, though the mist and snow may add to the magic.Spring and autumn are the best times to visit.
