Temple bar is on the far side of the world.
I mean, the far side of the world. It's in Arizona, not Nevada.
A totally isolated spot on lake mead. It is closest to the west rim of the grand canyon if that's your destination.
The west rim has NOTHING to offer except that glass Skywalk and a stark landscape.
Callville is your best bet as far as proximity to Vegas and still be on the lake.
There is a nice little Indian museum and restored pit houses between Callville and Overton. It is a must if you have kids with even the slightest interest. It's a quick diversion.
We used to haunt Lake Mead.
The boat that takes divers to the b29 crash site? That's my now sold dive boat.
I didn't answer earlier because you needed to do some research on your own.
I would suggest a night of offroad camping near the lake to get it all out of your system, and then find a casino campground.
I'd tour the dam, stay at Callville, continue the drive loop up through Overton then to valley of fire, in the back way to Vegas, and call it done.
I used to know the name of every lizard and snake on that trail.
There's plenty to see if you're interested in ghost towns and Mines and mills, but not anything else.
If geologic interests are your thing and you have an eye for it, the whole valley is absolutely compounded with dinosaur bone fragments and pottery shards.
Katherine is on a completely different lake about 60 miles south.
There will be few boats this time of year.
Nice place, right across the river from Laughlin and a dozen casinos. Nothing else there. A short jaunt to the dam and lake mead... But it's on lake Mohave, not Lake mead.
Cottonwood is on lake Mohave as is Katherine. Nice campground, not another thing for 50 miles around. You'll be at a nice beach on a DAMN cold lake.
Willow Beach is also not on lake mead, but on the river just below the dam.
There's a hot spring you can walk to. Lots of Marijuana there if that's not your thing...and you're captive unless you just get up and leave the spring.
But, willow is a favorite place of ours to stop for lunch, you're stuck there with nothing to do. It's a drive to the bottom of a canyon, lunch, view up at the dam, then on to Vegas.
Echo is a long walk to the water and I'm not sure the Cafe is open.
I don't know the first one you mention. I think it's what locals call Las Vegas wash.
It's where the multimillion dollar houseboats anchor and has all niceties that can be offered at a marina. Callville is the next stop down the loop, then echo,then the Indian museum, then Overton, then valley of fire,then Vegas if you're done with the loop, or on to Moapa for some true human sadness, then Vegas.
Katherine and cottonwood are on a different lake and temple bar is only good for hiding out and being VERY far into an odd rural area. If I were city folk, I might be a little uncomfortable getting to temple bar.
