Be sure to do “The Road To The Sun” drive.
We were going last half of July. Does the Sun Road get crowded? Does the park in general get crowded ? The Park Web site warns about shuttle stops. Example of bad timing would be visiting Bear Lake @ RMNP late morning in the summer.
from the NP website.....
“Depending on where and when you board one of Glacier’s free shuttle buses you may have to wait an hour or more for an available seat. “
Right; road to sun
also boat cruise and ‘Tea’ at Prince of Wales
