I’m sorry if you covered this in another part of your site, (either I’m technically challenged or there just isn’t a search function for your site) but I’m curious about Corfu. From what I can tell, you mentioned it once in your site under your post about best beaches. The Paleokastritsa area is something that has caught my attention for a while and is on my list, and then I saw pictures of Nissakids Bay and that looked kind of amazing.
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.
Crete, Santorini, and Naxos look quite doable within the 12-day block, but Crete’s beaches are scattered throughout a very LARGE island, Santorini really only has Kamari and Perissá (and some southern coast bays) and Naxos does have nice places to swim. If you choose only to visit those three islands in your relatively short time, you will do well.
My sister (32 years young) and myself (28 years young) are traveling to Greece from 22nd Aug – 6th Sept 2017. This will be the first visit for my sister and my second visit so I am trying to show her my favourite places as well as visit new ones myself (i have only ever been to mykonos and santorini). Our trip starts in Athens for 2 days, Mykonos for 6 days, Santorini for 5 days and leaving us with 3 days to spare at the end of the trip. (4th Sept – 7th Sept) We fly out of Athens in the am on the 7th Sept so need to be back in Athens prior to this.
As a starter to explore ferry services, go to the Ferryhopper.com and punch in your route searches. Note: air travel between islands is not generally good. Air travel is normally only feasible between Athens (or other mainland destinations) and the island in question. Some exceptions do exist – Rhodes Kastellorizo, Kos-Leros-Astypalaia, Thessaloniki-Limnos-Ikaria etc. but again you will need bookings weeks in advance.
We are planning our honeymoon in Greece. We can probably take up to two weeks. One of the places we want to go is Santorini. We would like to visit one or maybe two other places if possible. The other places we were looking at are Athens, Mykonos & Crete. Which of these would you recommend with Santorini if we were thinking of visiting 2 or 3 places total?
