I'm in fairly good shape and am not worried about climbing a steep mountain but . . . I do suffer from vertigo and get dizzy if I'm on a trail that has an immediate drop-off. Just how bad are the trails to the top? Are they wide enough where I can stick to the inside, or are they narrow where I will have no choice? If they are narrow, is the drop-off like stepping off of a bridge or is it more like a ski slope. I'm hoping I can work through this as I have heard the view is incredible.
