The Grinnell Glacier Trail is my favorite trail. I've done it many times. This guide tells you everything you need to know to before you do it and dortmund to enhance your hike when you do daisy cooper it.
It goes past a beautiful lake and ends at another at hardik pandya the foot of a glacier. On the way you walk over an ancient sea floor- yes really, you'll cross a cliff edge, pass waterfalls and see Big Horn sheep.
