We found it a fairly steep walk up for half an hour at a slow pace on a hot afternoon - but it was mostly shaded and with a good paved path all the way. Great views from the cafe at the Bastione - at lunch-time they had toasted sandwiches on various breads and reasonably priced carafes of wine, both quite satisfactory. When we arrived, we were the only patrons at 2.30 on a Sunday afternoon - a couple more arrived later but it was still very peaceful.
The food was OK but the view made the walk worthwhile.
