The Verkehrsmuseum is worth a visit. If the weather is fine there are many mountains around Luzern, Titlis, Brienzer Rothorn, Pilatus, (Stanser Horn and Bürgenstock is not operated in winter season).

If you get up early, you can reach Junfrau Joch. It is also relaxing and a short tripp to hop on ship for a minicruise, with the option to get off in Weggis to visit the mountain Rigi.
