A must visit while in the Cyclades, so much to see and do. My highlights are
Kleftiko,
Sunset at Playa,
Catacombs and the ancient theatre,
Pollonia fishing village
Venus statue was discovered here too, the site is in the same area of Catacombs and the ancient theatre
Tips for other travellers
Must go early to see Kleftiko, or there'll be lots of tourists spoiling the peaceful amazing nature
There're scheduled bus trips from the port to Playa or Pollonia, or negotiate a private taxi fare
There's a mining museum in town, wasn't that interesting to me
