We spent a day on this magical place. It was such a unique landscape to witness. It is a touristic destination so I would advise you to start your hike as early as possible in order to get the best out of it.
There’s hardly a bad time to visit Meteora since the Mediterranean climate is generally mild year-round and there are advantages to almost any season or time of year in Greece. That being said, July and August are the warmest months, soI would suggest you not visit Andros specifically for hiking.
We drove all the way from Athens. It is a 4-hour drive in order to reach Kalambaka and the Trailhead.
I picked the longest Meteora Hike that we could complete in one day and see the most out of it at the same time.
