On a budget, Thirassia Island Day-Trip still earns its price.
Ferry/boat ~€10–25; tours more
A genuine escape: a short boat hop to a sleepy island of a few hundred residents, donkey-quiet villages, simple tavernas, and zero crowds. The catch is that there's deliberately little to 'do' — limited transport, basic amenities, and a long lunch is the main event. For travelers craving authenticity over spectacle, it's a quiet revelation.
