The hike from the final car parking area to the falls is 0.6 miles and is fairly easy.
There really is no parking lot. You pull up to a path. I would not recommend someone with bad knees walking. It's not steep nor is it a smooth path.its far enough you feel like you'll never get there and you'll want to be able to stay to make it worth your while.
The walk isnt strenuous but it's a mile or so to the falls. It's by no means flat or paved but I'd take a few ibuprofen before you go if your knees are hurting. I'd park at the road though unless you have 4wd or your vehicle sits higher.
