The start of the stone walk is not immediately obvious, and is on the other side of the main entrance to Shuri Castle. You can catch the Monorail to Shuri, a 15 minute walk to the beginning of the castle gardens (which is free to walk through) walk through to the other side to find the path. From memory the path is narrow and between a shed and an apartment parking area. Once you start there are lots of options to explore gardens, tea rooms, traditional lanes and houses. The path is really steep and uneven but really authentic, take your time with the little ones and you should all enjoy (definitely not a path for a stroller). Once you get to the bottom you may like to pick up a taxi to take you back to your accomodation. Definitely not touristy and a very beautiful part of Naha!

Definitely not wheelchair friendly. In fact, even the walk down would be difficult for anyone with any walking difficulty. The stone path is very uneven. Walking up would be extremely strenuous and only recommended for those with lots of stamina.
