My husband is bery keen to hike the Primitivo. I'm a fairly tough hiker but - i must admit - i get really scared hiking along exposed, precipitous, ledge-type trails. I've been caught out with terrain like that in mid-hike and promised myself i'd never do that to myself again. Can someone please tell me, i know the Primitivo is steep and physically gruelling in parts. But are there sections that are high and exposed with sheer drop offs?
