I'm planning a trip to the Cyclades in May. After playing around with the openseas ferry schedules from last year it looks like I could do a Naxos>Sikinos>Folegandros>Sifnos>Serifos>Kythnos itinerary.
I like to see most of the major sites, go on a decent hike or two, and rent a scooter to get around the island. I don't spend much time on the beach. I've found 4 nights in Paros to be enough and 6 in Naxos. A month wasn't enough for Crete (just too much to see there), 3 weren't enough for Milos (didn't have a day to do the boat trip or get over to Kimolos). Two were enough for Santorini - could have enjoyed another couple days, but didn't feel like I was missing anything I had to see.
Any thoughts on how much time I should allot to those islands?
