Took a 7,200 mile road trip out west last summer. Drove from Vancouver Washington to Glacier so its a good day's drive from where you guys are in Seattle.
If you go then it is not an option, you have to get reservations just to enter Many Glacier. Most tourists don't even know their is another section of Glacier NP and only take Going-to-Sun road drive. It was super crowded like all NPs last summer before Covid19. We fortunately had the last cabin at Swiftcurrent.
Anywhere you can stay at Many Glacier is a great base camp for hiking since about a half dozen trail heads are within a half mile walk. Over 500 griz in the park so bear spray and practices are a must. See video -
Grizzly bear attack Glacier National Park << THIS ATTACK took place on the Grinnell Glacier trail a few years back.
If you guys are doing more intense hikes than those...
In the early 90s worked up in Alaska three summers pulling 17 hour shifts 7 days a week, living in a tent, sliming. Their were few women but the ones who hung were special. Seeing your pics. Reminded me of those special women.
