Known for its inspiring celebrity appeal - Leonard Cohen bought a house here in the 60s - Hydra is a pretty island of rising streets, whitewash mansions, and carefree clamour. Located a stone's throw from the Greek mainland, the authorities have resisted the temptation to cash in, meaning Hydra remains an endearing time-warp, which revels in life in the slow lane. With cars and new building developments banned – discover an island of donkeys plodding cobbled streets, and fishing boats undulating gently on the harbour’s waves.
