The crater is quite a wonder - especially as you approach it on almost level ground, crossing gravelly flats and suddenly there is a huge hole in the ground with a bright white floor. The scale of this is breathtaking. You can find a lot written on the crater in Wikipedia and you need a good look at a map to find it. There are not many signs.
The locals have their picnics on the edge of the crater which has scattered picnic tables.
If you are remotely interested in geology - this is a must. It is basically off the main Riyadh Mecca road for about an hour and a half drive. The roads are good.
The white floor of the crater is thought to be a result of salts being deposited from the crater steam. I didn't go to the floor - you need a day for that and it is quite a climb - if you can find the pathway.
