Before there were tour vans, there was the train. The Grand Canyon Railway has carried passengers from Williams to the South Rim since 1901, and this excursion builds the day around it: first class rail into the park — wide seats, big windows, the high desert rolling past — then a guided tour of the rim, and the train home.
It's the most civilized way to do the canyon, and for rail fans, multigenerational groups and anyone who thinks the journey should be half the experience, it's the obvious pick.
