I'm taking a month-long solo island-hopping trip later this year (September) and would love to hear your recommendations for Paros & Antiparos. I love the beach & will happily lose hours wandering around little towns. I love hiking too but not sure how I feel about doing it solo. It's been years since I've gone on an adventure like this and I'm so excited but really need to focus 
.
There is also the possibility of heading to Tinos & Syros but I think they'll offer less for solo travel. The other possibility is the Little Cyclades - Koufinisia etc).
