We are hoping to travel to the area late this summer with our 8 year old daughter, 14 year old niece and my in laws who are in their mid 70's. I am really looking forward to coming but my in laws, while they get around ok, are concerned that they will slow us down too much. Our intent is to primarily enjoy the park and it looks to me as though there are several areas that we can drive to and not subject them to a lot of walking. Would love to find a couple places where we could drive to see some sights, picnic, maybe swim or fish with a few short hiking trails that we (the younger bunch) could go on while grandma and grandpa just relax and enjoy the view. Any recommendations???????
