Athol was a railroad stop before it was a town. The Northern Pacific put a depot here in 1882, the village incorporated in 1909, and the population has held around seven hundred ever since. There is a post office, a library branch, a fire station, an elementary school, a couple of cafes, a lumber yard, and a veterinary hospital. That is most of it, and that is the appeal.
Rather than describe the place for you, here is the city's own site. The business directory is the honest inventory of what sits along Highway 54, and the history page is worth ten minutes if you care where a town came from.
If you plan the trip around one weekend, make it Athol Daze: a parade, a car show, a pancake breakfast, and a cake walk, run by the town for the town. These links open the city's own site in a new tab. We do not run it and we have no arrangement with the city; it is simply the best source there is.
