Lindau's old town sits on a small island in Lake Constance, its harbor gate framed by a lion and a lighthouse and its lanes still boxed in by medieval towers and gates. This self-guided walking tour traces the island's defenses, market squares and painted facades through the essential sights of Lindau. Everything runs from your phone. You get a clear map of all 9 stops, simple directions through Google Maps, and a short audio story with an interactive quiz at each location. The route runs from the Pulverturm gunpowder tower to the Münster Unserer Lieben Frau, passing the harbor's lion and lighthouse, the Diebsturm, the storybook Altes Rathaus, and the arcaded shops of Maximilianstraße. 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 from the moment you arrive, with no roaming charges.
