Follow the Celeb Path to Comporta, Portugal
Head down a dusty track along Herdade da Comporta, an expanse of coastline just an hour from busy Lisbon, and you could find any number of surprises. You will see solitary majestic villas - one reason why this stretch of sand in the rural Alentejo region has been compared to the Hamptons of the 1970s - or, like me, a sapphire-coloured expanse of lake with dragonflies dancing across its surface.
