Most parks offer some kind of accessibility to handicapped individuals.
You will find handicapped parking and wheelchair ramps at almost every Ranger Station - and at most day areas too. Unfortunately, campgrounds seem to be left out at almost every park. Most of the campground restores are accessible to people in wheelchairs but there are few camping areas that provide specific campsites for the handicapped. Most people don't seem to realize that there are plenty of handicapped individuals out there who do not require a wheelchair. A person confined to a wheelchair might not find a 300 foot trip to the bathroom distressing - but somebody who travels on foot and has limited mobility would find this a terrible trek.
