My favourite vista in Death Valley is one of the most popular.
As well as being a curious film by Antonioni (1970), Zabriskie Point is an elevated overlook of a colorful, undulating landscape of gullies and mud hills at the edge of the Funeral Mountains, a few miles from the edge of Death Valley …

I did a very popular hike / trail run from Golden Canyon trailhead in the valley. Up to Zabriskie Point. And back.
Fantastic.
A longer alternative is to add Gower Gulch making it a loop.
A number of deaths due to heat emergency are well documented here. Warnings are numerous.
