It is quite small so it would be a perfect quick fit, I personally was glad we went through before visiting everything else in the area. Everything you need right there : parking, loos, gifts, cafe and outdoor seating. You could get through it easy in a half hour, depends how much you stop and read everything. 🙂

I think it would be difficult for a person in a wheelchair to get to some of the sites. I was recovering from a broken foot and thought it was pretty rough going...mud, gates, and those grates on the paths to keep the sheep from wandering. I think the museum itself might be accessible...but I honestly can't remember if there are stairs to the entrance.

There is a path without steps from the car park to the Museum - don't use the short cut next to the toilets as it has uneven stone steps but keep to the track towards the front of the 'house' and left of the shortcut and you will be OK; it is a bit narrow due to shrubs but you will get down to the level of the entrance to the museum which is at basement level below the 'house'
