Spain's third-largest city, Valencia basks on the Mediterranean coast south of Barcelona. Amid rugged mountains and glorious orange groves, the city boasts impressive futuristic architecture, neon-lit fountains, a colorful old town and a bustling beach. The easiest way to explore the city is on the fast, efficient metro trains or, in the central areas, on foot. For a real taste of Valencia, try its famous nightlife, arrive during March's Las Fallas festival or try local firewater, Agua de Valencia.
