My favorite was a tour that I've mentioned several times in other threads. VIA Rail to Regina SK then south through N Dakota and S Dakota badlands, NW Nebraska, E Wyoming, Colorado, finishing at Las Vegas NM, then Amtrak home.

Highlights included three off the beaten track National Parks (Theodore Roosevelt, Badlands and Great Sand Dunes), Sand Hills of Nebraska and a 2 week layover at Crested Butte CO for their "Fat Tire Bike Week".

I enjoyed connecting the out of the ordinary start and finish locations and the Fat Tire Week gave me a fun sub-destination short of the trip's finish with a different kind of cycling. The route also had several challenging gravel road "short cuts" that added variety. Some highlights...
