🅰️PLAN A — most active. First summit + Cliff Walk + Trottibike. Best if everyone's recovered and you can leave ~07:30. Gondola up to First (2,168 m).
07:30Train Lauterbrunnen → Grindelwald (~45–50 min, change at Zweilütschinen). Gondola Grindelwald → First (2,168 m) — covered by the Jungfrau Travel Pass ✓.
09:00First Cliff Walk — suspended walkway with glass-floored platforms over the drop. ~30 min round trip.
10:30Trottibike descent — gondola down to Bort, then scooter 5 km to Grindelwald (~30–45 min). ~CHF 19/adult · CHF 14/child. Min height 125 cm — check the 8yo clears it.
12:00Quick lunch in Grindelwald.
~13:20⛔ Hard cutoff: on the Grindelwald → Wilderswil train (~40 min). Meeting point is Wilderswil, NOT central Interlaken.
🅱️PLAN B — Trottibike, late start OK. Drops the First summit & Cliff Walk: gondola only to Bort, then the 5 km Trottibike down. Keeps the kids' marquee ride, no summit altitude, comfortable rafting buffer. Works with an 08:30 wake / 09:30 departure.
~09:30Leave the apartment (grab-and-go breakfast). Train Lauterbrunnen → Grindelwald → arrive ~10:30.
~10:45Gondola Grindelwald → Bort only (skip going up to First). Buy Trottibike tickets ahead to avoid the line. Min height 125 cm.
~11:10Trottibike Bort → Grindelwald (5 km, ~30–45 min). Back in the village ~12:00.
~12:15Relaxed lunch in Grindelwald, then train to Wilderswil by ~13:20 (~45 min buffer before rafting).
🅲PLAN C — Grindelwald town, no ride. No gondola, no Trottibike — just visit the village, wander, lunch, then rafting. Relaxed. Note: Grindelwald sits at ~1,034 m (town-level, mild); if it's an altitude-recovery day, Plan D stays lower.
~09:30Leave the apartment (grab-and-go breakfast). Train Lauterbrunnen → Grindelwald → arrive ~10:30.
~10:30Stroll Grindelwald village — main street, shops, the Eiger looming over the town, coffee, playground. Easy, no exertion.
~12:30Relaxed lunch in Grindelwald.
~13:20Train Grindelwald → Wilderswil (~40 min).
🅳PLAN D — no-altitude recovery morning. Lowest option: no gondola, no altitude, valley/lake level (~570 m). Best if someone woke up rough after the summit. Skip Harder Kulm & any gondola.
~08:30Wake, hydrate, slow start. Unhurried breakfast in Lauterbrunnen.
~10:45Train Lauterbrunnen → Interlaken Ost (~20 min, sit-down, scenic).
~11:15Ground-level & restful — Lake Brienz shore by Interlaken Ost (turquoise water, benches, gelato) or Höhematte meadow (paragliders landing under the Jungfrau). Zero effort.
~12:15Early lunch in Interlaken or Wilderswil, then short hop to Wilderswil.
