Started at the beginning of Nellie Creek road which made for a 16ish mile roundtrip. Being as I got an early start (5:30am), the road hike wasn’t all that bad. If one was to start later though I could see where the extra 8 miles would be a slog. As others have said the actual trail is beautiful and there are lots of wildflowers this time of year. The last 1000 feet are tough as the switchbacks and the short scramble is rather steep. There isn’t much exposure though unless you really want it. Took about 6 1/2 hours to complete with some running mixed in on the downhills.
