The rocky peaks of Transylvania and Moldavia, snow-capped from mid-October in some years, call out for conquering, and well-marked trails lead to summits from all directions. There are less adventurous but no less rewarding walks through woods, meadows and villages in other parts of the country. The Danube Delta is a vast and unique protected wetland and makes a perfect backdrop for fishing, boating and, especially, birdwatching in spring. In summer, from mid-June to early September, the action moves to the Black Sea coast. Beach resorts fill up with swimmers, divers, sunbathers and partiers, who come for the all-night, open-air clubbing marathons.
