Later this month we will be driving from Whitefish to San Francisco visa Yosemite NP. We are traveling by RV and will have 3 weeks in wish to do this stage of our trip. We are looking for recommendations for a scenic route. We like the outdoors, mountains, lakes and sea. Part of the trip we are on has taken in Teton NP and Yellowstone NP and we will also visit Glacier NP before arriving in Whitefish. Thank you.
