Here are some tips for Greece in General:
Technical info.
AOPA Hellas INFOS and some general description:
AOPA Hellas INFOS Check in there the fuel availability. Not all airports have AVGAS. Also if you fly
to small remote islands keep in mind they have hours of operation and you should check the NOTAM's beforehand.
Keep in Mind Sitia LGST on your East is perhaps Greece's most GA friendly airport and has plenty of AVGAS, much cheaper than Iraklion LGIR.
For Santorini just call them up 1~2 days ahead to let them know you're coming. Even though there is no notam for this (this summer) they like to know the VFR inbound forecast for apron parking space as well. Santorini has no AVGAS.
Mikonos near by (Santorini) to the North with AVGAS is reachable but keep in mind it has limited parking for GA and although it is accessible for few hours stay it may be difficult to request overnight parking especially in a weekend.
Iraklion & Mikonos have fuel provided by EKO and that is why it is expensive (2.4~2.7 /Lt) Sitia is by AirBP (2.2/Lt). Refuelers prefer CASH and if you don't have change and give them big bill's you have to wait for the change.
Yes in some areas when flying low terrain may restrict VHF contact but they know you're there. Don't get anxious is they don't respond, just call a bit later. If they need to check up on you they communicate with MIL radar who can see you all over the country all the time. If YOU need to contact MIL radar they do provide Civilian R.I.S. (workload permitting) initial call up callsign is "TUGRIT" and frequency 129.80 with a basic position report & aircraft callsign. The station in charge of your sector will respond with it's own callsign. Officially as VFR you communicate with "Athens Information" 130,925 or 119,75.
If you want a nice island hopping to small relaxed airports (no avgas) fly north to Paros LGPA, Naxos LGNX, return via Astypalaia LGPL and Santorini LGSR.
This route keeps you in central Aegean sea, not too far from Iraklion LGIR and I assume with the Arrow's fuel range without need to refuel. Remember to check opening hours.

Sitia LGST
Sitia LGST airport Try "loukoumades" (tiny doughnuts in honey & cinnamon) at the eastern coffee shops downtown past the square; you won't regret it.
Santorini LGSR
Santorini LGSR Greece's most romantic views. Visit Oia to the North incl. the fish taverns at base of the cliffs, Fira town is too busy.
Paros LGPA
Paros LGPA Visit Naousa to the north.
Naxos LGNX
Naxos LGNX Checkout the beaches just SW of the airport and the villages up high in the mountain on the Eastern side.
Mikonos LGMK
Mikonos LGMK Too much to see, beaches, downtown, they're all excellent but too crowded July & August.
Astypalaia LGPL
Photos: - Aircraft Pictures | !!!!!!!!!!!!!! Have a coffee up in the main town overlooking down the cliffs
Milos LGML
Milos LGML Lots of nice places in Milos, can't recommend only one !
In Greece VFR is easy, you'll have no trouble. ATC usually want you BELOW the IFR traffic levels and to be there before reaching their airport zone.
Just be careful at Iraklion because it is VERY busy at times and be precise at your initial position report and estimates. ATC do their best to squeeze you in between heavy IFR traffic when you get to the traffic pattern and will keep you well below IFR all of the other times. They have approach radar and they will monitor you on radar all of the time.
Over sea where you have terrain near by and wind coming from its direction expect turbulence. Winds in Aegean during summer are usually N-NW directions 10~40 kts.
Pass my Regards to George Kelarakis (the boss) if you meet him up in Cretan Eagle. He tried hard to get this Arrow.
Enjoy
