A suggested 7‑day itinerary: Zurich (old town, cathedrals, Limmat river, Lindt Chocolate factory), Rhine Falls (both sides, circular walk, boat to central rock), Lucerne (Chapel Bridge, Lion Monument, nearby mountains Pilatus/Titlis/Rigi), Interlaken base with Lake Thun/Brienz boat trips, Harder Kulm viewpoint, Jungfraujoch “Top of Europe”, Lauterbrunnen, Mürren, Grindelwald, plus Iseltwald/Wengen if time. Consider replacing one day with Zermatt. A Berner Oberland Pass can greatly reduce transport costs.
