The smoke was not a problem, even though it was just over the hill.
The trail showed obvious signs of heavy usage, but was also well maintained. The signage made the path obvious. There was very nearly stairs all the way to the top. I saw plenty of folks over 60 doing the trail, even all the way at the top. Most folks turned back about halfway, but there were a ton of people. However, it was not too crowed. We found a parking spot at the bottom without waiting.
I think that this late in the season it is less busy and crowded.
The views are incredible, even with smoke. All the way up, there's an un-blocked view of the granite peaks. The glacier at the end is awe inspiring.
Loved the hike, the views, the weather. Great time for wild flowers in the higher elevations. Take a lot of water for drinking!
