Paros

The island's capital unfolds an old quarter of limewashed alleys, bougainvillea and chapels around the remains of the Venetian kastro built from ancient column drums. On a lead, early in the morning or at sunset, it is a delicious labyrinth, and the seafront gives a long flat promenade.

The most photogenic little fishing port in the Cyclades squeezes its colourful caiques against a half-sunken Venetian fortress. Leashed dogs happily wander the quays and lanes, and many harbourside tavernas accept calm companions at outdoor tables.

The old marble-flagged road links Lefkes to Prodromos in an hour of gentle descent among olive trees, drystone walls and chapels, with the sea and Naxos as a backdrop. It is the island's finest walk for a leashed dog; start early, shade is scarce at midday.

Seven hundred metres of golden sand on the east coast, swept by the meltemi that has made it a world-class windsurfing spot. In summer, keep to the undeveloped ends, away from the sunbeds and sailing schools; off season, the whole beach belongs to you and your dog.

The church of a hundred doors, founded according to tradition by Saint Helena in the 4th century, is one of Greece's most important early Christian sanctuaries. Dogs enter neither the church nor the cloister: take turns visiting while the other waits in the shade of the forecourt.

In the bay of Naoussa, wind-sculpted granite rocks carve out a series of miniature coves with transparent water. Off season and early in the morning, dogs explore this lunar landscape freely; in high summer, aim for the coves furthest from the sunbeds.
