The trail was not paved, but it was graded and gradual for a good stretch--to within sight of the river. More venturesome folk can climb over rough terrain to get closer after the graded trail ends. You will have to judge regarding someone using a walker. An individual who is very unsteady on their feet, I would not advise going. A person who uses a walker minimally, gaining strength after surgery or some other medical procedure might well give it a try. Signage indicates the graded path is wheel chair accessible.
