A quiet place by the lake
The road is paved until the end but you can manage easy with a 2 wheel drive vehicle. I parked right along the water but beware, there are lots of bugs. The water can be chilly since Lake Mead is very deep but in the spring and summer the water is really nice to wade in.
Plenty of spots for fishing. Bring a chair, sunscreen, bug spray and water. The water is a bit calmer since most of the boats go on the other side of the lake.
I would recommend going around the sunrise or sunset because colors are quite stunning.
