Most of US 64 across New Mexico is relatively tame, and the bulk of it is two-lane highway.
You will find grades and curves as the highway goes up into and back out of the Moreno Valley (Eagle Nest, Angel Fire). There's one short pass (Palo Flechado), but it's only a two-mile climb.
Once again, you'll find grades -- but not many curves -- as the highway goes from Tres Piedras to Tierra Amarilla. It's high, beautiful and lonely mountain country up there with some large pull-offs toward the western end for picture taking, lunch, etc.
