Hi Sarboy!
Refer the site
SkyVector.com - Aeronautical Charts - Flight Planning for the US based FAA VFR charts. Punch in the airport identifier, like when i flew to Vegas with my Instructor we used Hendersen Executive (KHND). You'll have the chart and can refer it right away.
There's a note on the VFR chart i have with me now that says "
Extensive concentration of tour operations daily between the grand canyon national park and the las vegas Class B airspace. All VFR traffic operating between these boundaries are encouraged to monitor/communicate on 120.65. ATC clearance required before entering the Las Vegas Class B Airspace"
My volatile memory cant recollect more than this, but all i can say is that the view is breathtaking and will last in your mind for a very long time. Having said that i'd also advice you to Fly Safe because of the Terrain.
And i think single engine VFR is permitted, given the conditions then.
Have a good one mate!
Cheers
Learning to Fly (Always will!)
