The warm-up hike I did was to Heart Lake (where I stopped at an overlook above the lake, it was about 11,000 feet elevation) and back, about a 6 mile round trip. I think the pass is about a mile and a half beyond Heart Lake; it was later in the p.m. and starting to rain so I didn't go all the way to the pass.
