You can do a drive by if you're interested. We travelled down to see Salvation Mountain (which I think is worth a look), stopped at Bombay Beach and drove past Slab City. If it wasn't for Salvation Mountain, I don't know if I'd bother.

Driving through Wonder Valley elsewhere in California is interesting, and then reading about why almost every building is exactly the same size.

There are several documentaries set in Slab City or nearby towns Niland and Bombay Beach -- I found all of them fascinating. Sorry, don't remember titles.

A safer alternative destination might be the Fountain of Youth Spa, which has been there since at least the 1970s. But I'd check the recent reviews, and hold off until November at least.
