Freycinet National Park is very well maintained, and the steep walk up to the Wineglass Bay Lookout is via a well established path with lots of steps. The walk down is a slightly different route (less steps and more of a winding track). The view point is very good, but unless you have perfect conditions, ie full sun and no wind, you may not get those perfect postcard pictures. Definitely worth doing (I am a Grannie with crook knees) and I think the area that the trail cuts through is just as beautiful as the lookout. Amazing granite outcrops and beautiful vegetation.
