Went out to Staircase Rapids after reading that it was open.  I drove out there and found that the road was not open to the ranger station. So I went ahead and rolled out to the ranger station.  Mostly it was level and it was paved for the 1.2 miles up to the ranger station with lots of little waterfalls along the side of the road. You can see some of them in the gallery (see link below).  While I was not able to go all the way to the rapids because the trail had a couple of steps that I could not get my chair over which I was expecting and really didn't have a problem with that until I got back to the ranger station and noticed that the restroom was not accessible to wheelchairs.  It is labeled as accessable and looks like it would be big enough but  there is a 3 inch drop off to climb onto the concrete pad.
