Here's a place you may not know exists -- but it might be getting too hot to go very soon (at least until mid September).
Havasu Falls -- in Arizona.

No roads in. You can either hike in (and stay at a lodge there), or helicopter in. I plan to do this one day. Ben still a bit too young for the long hike.
It's the only town in the continental US which can't be accessed by roads.
