I went last year, well, i was going from Las Vegas to Yosemite and took the route Via Death Vally. Its quite a large area.
Roads are long and straight, temperature is very hot.
There are signs to turn off your air con due to excessive heat. Think we saw 109 degrees (that day we went from 3ft above sea level to 9500+ft above sea level).
Hot, yes, very!!! Not much shade, and most of DV seems like those small deser4t villages, tumbleweed rolling accross the road etc..
Still, worth a vist. Damn hot though. They have water stops for your car
One of the roads leading in.... Just over that hill/moutine..
From the big fruit machine on-wards isthe death vally images....
