One good visit can set the pace for a day. Use these shortlists to decide what to book, what to do on foot, and which stops still work if the museum is closed.
Rail and walking
Alsace
Start in Strasbourg. Make a separate choice for Colmar and Obernai. That leaves one hotel room to come back to and keeps the shorter days flexible.
Give yourself time to look at the pink sandstone from the square before going inside. If the astronomical clock is the reason you’re coming, check its visitor arrangements before you set your day. Ordinary visiting hours can change around services.
Follow the canal banks toward the Ponts Couverts, then come back through the lanes. It works as an afternoon after the cathedral or as the entire outing if you’ve just arrived. Wear shoes you’re happy to walk in on uneven streets.
Start at the museum if you want the Isenheim Altarpiece, then walk south through the old center. On a Tuesday, when the museum normally closes, make the canals and streets the day. Check your train back before choosing a late lunch.
Start in the center and walk a short section near the ramparts. Obernai is the easier extra day when you want lunch and a walk without a second museum. Set the return train before deciding how long to stay.
Start with the palace, where the rooms and route are the visit in their own right. Read the access information before choosing a slot if stairs are a concern. Decide about the bridge after lunch, with the current last-entry time in mind.
Start with the arena and add the Roman theater if the opening hours and your energy line up. If you came for archaeology, leave time for the museum instead of trying to cover the whole city. Use your return train as the stopping point.
03 · Allow a half-day if exhibitions are the priority
Mucem and Fort Saint-Jean, Marseille
Choose an exhibition before setting out. The fort and the J4 building are connected by a footbridge, but it has its own closing time. If you only want the views, check access to the outdoor spaces. Tuesday is normally the museum’s closed day.
Start by the boats, then walk toward Le Panier when you’re ready to leave the quay. This is a good first afternoon or a backup when the museum is closed. Keep the route close to the water if steep lanes or steps would make the walk difficult.
