AFAIK, the metro (https://www.siasat.com/saudi-riyadh-...-2023-2540582/) should be opening later this year. Then again, perhaps that's been the case for years....

I've been to Riyadh on a few occasions, having most recently stayed at the Mövenpick Hotel and Residences Riyadh near KAFD. Unusually, Google Maps mentions something called the "Ghadeer Walking Trail" right nearby. No idea what the heck that means.

Also, to reach the KAFD by foot apparently would've taken 1.5 hours, even though it's physically RIGHT there (https://maps.app.goo.gl/2VCyaNzbC3UW4YgG9).

Suffice it to say, save for the Shams restaurant neighborhood, and maybe the diplomatic quarter, it is a very unwalkable city.
