Better route out of West Yellowstone up to Two Medicine, we have taken us 191 before & found it a nice scenic route up to I-90, question is, is US 287 as good or better, looking on Google street view,...
Last summer, we really enjoyed driving 287 from West Yellowstone to I-90. Especially enjoyed the first part past Hebgen Lake and Earthquake Lake. After that, it's just a very pleasant, easy drive.
