It starts off on a slight uphill grade. Many parts of the beginning of the path are very easy. There a sign in/out book. I suppose so they can make sure everyone who went up also came back in one piece. It's also fun to look and see where the other visitors are from.
It gets progressively steeper. There are rock steps some placed, some natural, and some may be carved out. I wouldn't say the last bit of the trail is straight up but it is a climb. There is an outcropping before you get to the top where you can rest and see a wonderful vista. When we got all the way up there were a few kids up there (with their parents, of course) ranging in age from about 8 to 14. You can walk onto the "devil's bridge" for a picture but it is a little scary just because you are so high up and there are no hand rails. I would recommend proper footwear.
