My wife and I are planning an eleven day stay on the BI. We will have a car and plan to have our base in Hilo. We like to walk and would appreciate suggestions for walks/hikes in any area of the Big Island. We have looked at the HVNP web site and have a guide book for that and other areas, but we would like suggestions from others who have been on the Island. We do 1o miles or so a day, sometimes 15.
