When should I avoid Santorini?

Mid-July through August. Cruise-ship density peaks, hotel rates double, and Oia at sunset becomes a single-file shuffle. Late May, early June, and the second half of September are the working windows.

Is it worth booking a caldera-view hotel?

Yes — the view IS the experience and an inland hotel will leave you taxiing for every meal. But avoid the lowest-tier 'partial caldera' rooms; they tend to look at neighbours' staircases more than the volcano.

Should I do the Oia sunset?

Skip the famous Oia spot — it's a 3,000-person crush. The sunset from Pyrgos Castle, Skaros Rock, or your own hotel terrace is genuinely better and unphotographed.

Best time to visit Santorini

The short answer

When Santorini is at its best

Santorini is the most photographed Greek island and the one that is easiest to get wrong. The cruise-ship onslaught is real (six big ships a day in peak season), the Oia sunset is now a queueing experience, and most of the famous caldera-edge hotels are smaller and tighter than the Instagram crops suggest.
