On Lake Zurich in Kilchberg — Lindt's home since 1899 — stands the planet's largest chocolate temple (2020), opening with the scene that broke the internet: a 9-meter chocolate fountain pouring into a floating giant praline. Inside: an excellent interactive cocoa journey, three effectively unlimited tasting stations (skip lunch first), bookable chocolatier workshops, and the world's biggest Lindt shop with exclusive flavors. 12 minutes by train or a summer boat ride; book online — slots sell out — and allow 2-3 hours. The perfect rainy-day card.
