While travelling around Europe a few years ago, one of the most memorable things I did was trekking around the old peak top monasteries in Meteora, Greece. There are guided tours and buses, if you want, but I found that the magic and serenity of this place was best experienced on foot, alone and unrushed.
Metéora (Greek: Μετέωρα, “suspended rocks”, “suspended in the air” or “in the heavens above” – etymologically similar to “Meteorite”) is one of the largest and most important complexes of Eastern Orthodox monasteries in Greece, and incidentally, Metéora is included on the UNESCO World Heritage List. Six of the original monasteries remain today. They were created to serve monks and nuns following the teachings of the Greek Orthodox Church.
The monasteries were established sometimes on the 11th or 12th Century and the are all built perched high on cliffs and pinnacles in the area and thus were deliberately difficult to gain access to, back in the day the only way to get inside was by means of rope, buckets or net ladders lowered down from dizzying heights. Access today is much more friendly, with ladders and walk ways having been cut into the rock and built for tourists.
The nearest town is Kalambaka, reachable by bus from Athens (couple of hours), plenty of accommodation is available. You can then just do a small walk, or perhaps even a bike ride up and around the valley. The tour buses only visit one or two of the biggest or most important monastries, by walking or riding alone you can choose which ones to visit and linger at. So, if you are ever in Greece, make the effort to go inland, and visit places, trekking around the old peak-top monasteries in Meteora, Greece was an experience I will not forget in a hurry.
