The Agios Yannis beach with a clutch of great beach villas is a good place to start: rent a car and go exploring. You won't be disappointed unless you like your beaches bustling with loungers and waiter service.

Tinos is in the Cyclades islands, a two hour catamaran ride from Athens. The quicker journey is from the small port of Rafina on the north coast and very close to the new Athens airport (no need to go into Athens).
Alternatively, ferries and catamarans go from Pireus, or you can fly to Mykonos and take a 20 min ferry to Tinos.
