Your ship ties up right beside the old town, so you can step off and walk straight into one of the oldest cities in Western Europe, take it in at your own pace, and be back on board with time to spare. Explore Cádiz with a self-guided walking tour on your phone. You get a clear map of all 10 stops, simple directions through Google Maps, and a short audio guide with interactive quizzes to play when you reach each location. The route runs through the heart of the old town, from the port to Plaza de España, passing the Roman Theatre in the Barrio del Pópulo, the golden-domed cathedral, the Torre Tavira watchtower, the constitution church of San Felipe Neri, and the Gran Teatro Falla. Start anytime, pause whenever you like, and explore freely. No groups, no schedules. Audio and text available in 7 languages. And it comes with a free eSIM, redeemable once per account, so your map, directions and audio work the moment you step ashore, with no roaming charges and no hunting for wifi.
