Oslo, 24 hours, limited mobility, suggestions?

I'd suggest the Viking Ship Museum. It is quite small, manageable, and the ships are on one level.

My favorite place on Oslo is the Vigeland Sculpture Garden in Frogner Park; however, the park is very large and requires a lot of walking. If you had a wheelchair, it would work.

p.s. I don't have a good suggestion for a church or castle there. There is a stave church in the Open Air Museum, but that requires a lot of walking.

The Viking Ship Museum might prove a bit difficult for someone with mobility problems as well. It's about a 15-20 minute walk from where the boat from Oslo's harbour disembarks. If she's interested, the Norwegian maritime museum and one devoted to a polar exploration ship (forgot the name) are adjacent to the dock. The Nobel Museum and Norwegian National Musuem are pretty easy to reach on foot also.

The only castle I know of in Oslo is the Akershus, and that might prove problematic for someone with mobility concerns. If she wants to visit the national cathedral, you can get there fairly easily via tram, but it's fairly small and rather unadorned for a national church.

For dinner, try one of the restaurants on the Stranden (sort of like a harbor boardwalk). Great people-watching zone.

For the Viking ship museum, you don't have to take the ferry. I believe there is also a bus that goes to the Bygdøy peninsula; however, I don't know how far the bus stop is from the museum. You could definitely go by taxi.

I think the Polar Exploration Museum that Tom mentions is referring to is the Fram Museum. If so, I don't think it would be a good choice. The museum is basically multiple levels of catwalks around a large ship and then you can step onto the ship and see parts of it. I think it would be challenging with mobility issues.

The boat museums, together with the Frogner/Vigeland park were certainly the most memorable parts of my visit to Oslo, twenty years ago. Bus #30 departs from the train station or the National Theater to the Bygdoy area. According to the map in Rick Steves' Scandinavia book, the bus stops are right in front of the entrances to the Folk (open-air), Viking, and Kon-Tiki museums, but further from the entrance to the Holocaust Center. The bus runs once per hour in each direction. "Note that after 17:00, bus and boat departures are sparse."

Thank you for the information. It is very helpful, sounds like a museum tour might be out of the question for my mom but the dinner suggestion should work.
