I can confirm that they have improved the path, smoothing it out and creating some ramps.
Of course, they also added a shuttle, which will carry you from the parking lot to the top of the hill. This picture is taken from close to the top of the path, so that gives you an idea of the distance. (Obviously the shuttle would have been easier, but apparently we have something to prove.)
A much easier path takes you back down, with accompanying signage that is informative and at times humorous.
I had not been to the Garden since October 2008, and they have made a lot of improvements in the paths and facilities.
Of course, things can also get slippery when wet, which it was on our day.
That is a higher than normal water level.
The rain doesn't change it from being beautiful. It is more effort than the Lan Su Chinese Garden, but it also has more variety.
One thing that may have delayed our return was the ridiculous crowds we encountered the last time. At one point it seemed like there were 70 people standing around trying to get a picture of one tree.
As anxious as we are for the pandemic to end, some attractions are enjoyed more easily with visitors spaced out and timed entry. I was also pleased to see a new $10.00 tripod fee; that should help.
Although I would not have gone out of my way to plan it, I am glad that I got to experience the garden with rain, and see that side. Fortunately, in Portland, the odds of that aren't terrible.
