Athens to Santorini: Ferry vs Flight Guide (2026)
ℹ️ TL;DR: In 2026, the fastest ferry from Athens to Santorini is the SeaJets high-speed catamaran — 4.5 hours from Piraeus, from €55 one way. The Blue Star conventional ferry (7-8 hours, from €35) offers the best value and a genuinely enjoyable Aegean crossing. Flights take 45 minutes but cost €50-180 and require airport hassle. Most visitors take the ferry one way and fly the other. Santorini is roughly 300 kilometers southeast of Athens, floating in the Aegean Sea like something a movie set designer dreamed up. The caldera, the sunsets, the blue-domed churches — you already know what it looks like because it’s on every Greece travel poster ever printed.
