Float up on the Firstbahn to Grindelwald First for the photogenic Cliff Walk by Tissot, wide-angle Eiger views, and the classic hike to Bachalpsee (allow ~1–1.5 h each way, easy to moderate). Add a relaxed terrace lunch or dial up the thrill with First Flyer/Glider or mountain carts on the way down. Start early for calmer paths and clearer reflections at the lake. After the descent, elevate the day with a refined dinner or spa time in Grindelwald or Interlaken to round off the alpine high.
