Or Vegas...easy to fly in from here
I've always thought of the S. Lake Tahoe airport a being a private plane hangout. I haven't seen it in a while though, it might be large enough to handle commuter twin props from Vegas. If so, Vegas might have better schedules as Reno is close enough that air travel isn't a need.
Those hiking pics you posted are right there too, definately within biking distance of the Casinos if one chooses not to drive. It's parking area, trail, pristine mountain lake, trail, pristine mountain lake and then summit with a spectacular view of Tahoe.
