We did this hike on a beautiful Saturday with temps in the 70s. Starting at the bottom it get progressively steeper with long runs of stairs winding through the forest along a little creek. It's very well maintained and has a good canopy for shade although it could be pretty brutal in the summer.
Only negative is the number of other people, especially those that don't have much ettiquette when it comes to yielding right of way, but overall it's a great hike.
