The walk from the road at the top of the hill is rough. I can’t imagine it would be much fun in wet weather, as it is a rut through about a foot of peat. Could be quite tricky.
However, it’s worth the effort. This is a fantastic space. The slidey metal hatch, the useful torch in a box, the superb quality corbelling and the ladder down into it all contribute as does the excellent view.
The passages are very low and muddy knees seem to be the order of the day to get into the side chambers.
I visited four tombs (5 if you include Mine Howe), on Orkney, this was the best by far. It isn’t as grand as Maeshowe, but it has a superb beehive corbelled chamber, and a much more emotive sense of place.
