National parks and reserves

The last wild beach at the southern edge of the Danube Delta Biosphere Reserve: shell-strewn sand, dunes and a low earth cliff, with no hotels, sunbeds or lifeguards.

A 98-hectare former lagoon between Saturn and Venus, with reed beds, open water and sulphur springs where swans, egrets and black-winged stilts stop over; you watch it from the surrounding roads.
