my wife has to use a mobilty scooter. how accessible is the park for her

Iam sure you can enter the welcome center. Also as other guide stated all of the overlooks are flat surface. Give it a shot. You'll enjoy.

There are about 75 points along the drive where you can pull over and see from the overlooks, and if your vehicle is tall you probably don't need to get out to enjoy the views. The visitor centers would also be accessible. As far as hiking or exploring, you would have to find an area that meets your needs. You definitely would not be able to get to any of the waterfalls, but there may be some other places you could explore.

Very

Sorry no idea for mobility scooter..

Most parking lots have handicap parking and ramps to access the sidewalks. Those that don't can still be seen from the parking lot. The trails on the other hand are not mobility scooter friendly. Hope this helps!
