Attraction· 7 min from marina (513m)
Sifnos is home to an extraordinary network of 77 ancient towers — more than one per square kilometer — making it one of the densest concentrations of ancient defensive architecture in the Aegean. Many sit in remote spots across the island, rewarding you with both a slice of living history and some seriously scenic hiking. If you're into archaeology or just love stumbling onto something genuinely rare, tracking these towers down is one of the most memorable things you can do here.
