Yes...the roads are paved and in good shape. The pullouts are a bit rough though.

If you want to stop and see the falls, it could take a little longer, because by going back thru Ft Payne, you do some backtracking. Here is a shortcut and might make the round trip about 40 min. Exit 218, right turn on hwy 35, follow that thru town. It will turn right and go up the mountain. You will cross hwy 89 and the falls are about 5 miles ahead. On the way back, when you get to Hwy 89 turn right, immediately you will turn left on Beason Gap Rd. Follow it downhill, when it dead ends, turn left, then the first right. This will take you to hwy 11, turn right and follow signs to exit 222 I-59. Another option would be to go straight on hwy 89 thru Desoto State park you will want to stay there sometime. Stay on 89 until you get to Desoto Falls, turn right. Visit the falls, 8 min, then when you come back, go straight across hwy 89 and take that short cut down down to I -59. I take the scouts up there on the way to summer camp and we usually spend two days there, hiking, swimming

Little River is a whitewater river. There are 3 sections, upper-experts, upper two (lower two) advanced, and chairlift to canyon mouth park is intermediate with a couple class IV rapids.

That all depends on your conditioning. You can drive along the scenic highway, walk and view the water fall, go swimming at the falls, or "little falls" all of which are fairly easy to get to, or rappel and climb cliff's, whitewater kayak the river, basically for experts and advanced paddlers,and there are a couple of hiking trail. Need more explicit info, find solo nutiket

There is handicapped parking in front of the visitors center but I do not know where the swimming area is.

The waterfalls have a boardwalk that is wheelchair accessible; if a wheelchair is an option since she can’t walk far. There is a beautiful overlook of the falls so it would be well worth it. If that isn’t an option you can see the back of the falls as you drive over the river. There is a large parking lot next to the boardwalk and it isn’t too far of a hike to see the falls. The boardwalk was very helpful for me. The scenic drive has many overlooks that don’t require walking but a few feet. I have a bad leg and can’t walk long distances and I was able to enjoy this park immensely. I wouldn’t definitely give it a try because it is a beautiful place.

Dawn to Dusk for hiking but the main road is open 24hrs!

I've never been fishing there and have never seen anyone else fishing. You could probably fish with a simple rod and reel, but fly fishing would probably be difficult in this area.

Yes, several locations. Hippie hole, Blue Hole and Martha Falls. Find on the information signs.
