We tried this place as a quick weekend Overlanding Trip to get the kids out of the house.
Took close to two hours from Salt Lake City, once you turn off I 15 you’ve still got close to an hour. The road wasn’t too bad, pretty Wash boarded but fairly certain most cars could do it if they are careful around a couple of spots.
There is a train museum along the way that looked pretty interesting.
Once you get there, there’s a parking lot right above the spiral jetty, you could park there and camp if you wanted.
If you have a bit more of an off-road vehicle there is a couple of camping areas down just above the Lakeshore that we camped in. You will need a 4 x 4 with decent clearance. We did it with a stock suburban just fine.
We couldn’t even see the water line, dry Lake bed is pretty much all you can see.
It was rather fascinating to look at and we did enjoy the time there. But I don’t feel like it would be a place I would want to camp more than one night because I think the kids would get restless.
