Fodor's Expert Review Giurgiu-Rousse Friendship Bridge
Take a stroll from Romania across the Danube to Bulgaria on one of just two bridges connecting the two countries. (The other runs between Calafat, Romania, and Vidin, Bulgaria). The bridge is about 3 km (2 miles) long, but the distance between the centers of each town is a little over 10 km (6 miles). Still, it's not a difficult trip and, as you stroll across the bridge, you can watch the boats on the river below. Don't forget to bring your passport. It's also easy enough to hitch a ride across.
