This is a great place to dig for white opals! I come here several times a year to dig for opals and search for other rock, there is a ton of chalcedony in this area which I like.
The dirt roads are okay but not great as far as how rough they are, but you don't have to have a 4x4 so that's good.
There's quite a few spots and they are spaced far apart, I've seen a wide range of camping setups, I tent camp so I tend to look for dry creak beds, this area is pretty rocky so air mattresses are your friend.
In the deeper areas of old river beds the hills will be 15-30ft tall, look for a dark green/gray line and when you find whites spots that's where the opals are, you can chip away and find decent sized veins of white opal.
When you get them wet you will see blue, red, green and yellow amongst other colors.
This is dispersed camping so there are no amenities to speak of, but there is a small town of Tecopa near by with a few small places to eat.
There are also hot springs in this area follow the signs they are everywhere, be forewarned that foreigners come into this area as well and tend to go into the hot springs nude. There is another camp close to the hot springs that has amenities if that's what you like.
