Motor cars are not allowed within the park. Tourists must either walk or hire one of the electric shuttle buses which are available for 10 per person per ride. Walking is preferred and is the only method by which to mountain summits may be reached. The main roadway in the valleys is well paved and wide. The mountain tops are gained via well defined, stone laid, paths and stairs. These mountain paths are very steep. For those who are less fit, three cable car routes can convey you up the hill sides. However, none of the cable cars will take you the whole way, leaving you some climbing to do by yourself.
