Keep movement honest
The best transport plan is Old Town and Bock first, Corniche and Grund afterward, Kirchberg separately.
- Anchor the day around Bock Casemates or Chemin de la Corniche.
- Keep Pfaffenthal lift for the right weather and timing.
Getting around Luxembourg becomes easier when you stop treating every stop as equally close. I would choose the base first, group the nearest anchors, and leave the wider move for a clean second block.
The practical rule is simple: Old Town and Bock first, Corniche and Grund afterward, Kirchberg separately. That keeps the day grounded instead of making it feel like a loose checklist.
