For a gorgeous shorter hike, try adding Rockwell Falls in Glacier National Park to your list. There’s beautiful views, and of course a gorgeous waterfall as well.
Rockwell Falls wasn’t our main destination for the day, but it was so magical when we got there it was definitely hard to leave. We were actually heading for Two Medicine Pass, and knew we’d be seeing both Rockwell Falls and Cobalt Lake as well.
We loved all 3 destinations so much, I highly recommend any and all. To do everything, you’re looking at 17-19 miles give or take depending on how many side trips you take. So with that in mind, Rockwell Falls all by itself makes a great short(ish) day hike.
