The first part of the walk is flat with a concrete path suitable for wheelchairs and strollers but the last bit is narrow, rocky and sloping. The views are spectacular of the river (including a few dolphins) and the breeze on a warm spring day is enlivening. No need to walk on the sand as you pass by a couple of beaches as there are formed paths the entire length. I walked for half an hour before stopping at the lookout at the base of windmill hill before returning via the same route. You can even stop along the way for a drink as there are bubblers and coffee shops. A great walk at any time from sunup to sundown
