You've likely seen the area since your post and I don't check this profile often so I apologize for the extreme delay. The last time I went there, around the time of this post, there were no construction sites by the lower plant.

I don’t think so.

Hi there - I used an Uber. It cost about $25 to go there and $39 to come back

Yes there are places to hike.

It is free.

Not that I know of. I have been there 3 times and the handicapped access is a ramp system that takes you to a viewing platform with glass walls. A person in a wheelchair will get a fabulous view.

It is so short that it's not really a hike. It takes less that 5 minutes.

I believe so not that far

The falls are open from sunrise to sunset. Use the parking lot opposite the falls. There are more spaces there. There’s a walking bridge over the road.

There are several steps to navigate down to the lower viewing area. Not really conducive to strollers. There is another viewing area higher up that may be flatter, but I am not sure.
