The other groups are best tackled individually. For example, the Ionians have no ferry connections to the rest of the Greek islands; the same story with the Sporades and the Argo-Saronics. The NE Aegean islands do have a link to the Dodecanese and the Cyclades but are probably best left for another trip once you have got the feel of the rhythm of the Greek islands.
Are you interested in what is happening in the sky above you? If so, then you share the same interest as two Swedish plane enthusiasts. They were also curious to know which aircraft was flying over the heads at any particular moment and wanted to know the destinations of those unknown aeroplanes. At the time, however, it was impossible to get hold of that information. What they did know, though, was that each aircraft is fitted with a transponder, which sends details about the aircraft’s speed, the flight path and the current altitude. Most airlines use a technology called ADS-B, which is an abbreviation of ‘Automatic dependent surveillance - broadcast’. The two Swedes wanted to make use of the information provided via ADS-B and put their plan into practice. That’s how the idea of Flightradar24 was born.
Those are 3 great islands. Corfu is much more green than Crete and Santorini and does have a different feel (more Italian but it’s no where near Turkey). The trouble with doing all 3 is that Corfu is on the opposite side of Greece from Crete and Santorini so you’d need to fly via Athens. It’s better for most people to visit another Cycladic island (Naxos, Paros, Milos, Folegandros) instead of splitting up their trip between the two sides of the country.
