30. Cádiz, Spain: Europe’s Oldest Continuously Inhabited City

Often overshadowed by its glitzy Andalusian neighbors, Cádiz is a coastal gem brimming with history, character, and sunshine—all on a budget. As one of Europe’s oldest continuously inhabited cities, Cádiz offers layers of ancient history, from Phoenician ruins to Roman theaters and medieval cathedrals. Its golden beaches stretch for miles, offering a peaceful escape from the tourist-packed costas. Wander through the atmospheric Old Town, where narrow lanes open into lively plazas lined with tapas bars serving fresh seafood and cold sherry at incredibly reasonable prices. Head to La Caleta beach for sunset, or climb the Tavira Tower for panoramic views of terracotta rooftops and the sea. Cádiz combines the slow pace of a fishing village with the cultural richness of a historic port—all while staying refreshingly affordable.
