This was a tough but thoroughly enjoyable trip in a very beautiful part of the world. The challenging grade is about right; be prepared for a lot of rocky steep ascent and descent including a fair amount of scrambling and using fixed cables/chains. Some parts (particularly the ascent to La Om on Day 4 and the ridge along the top) are pretty exposed. There is a good mix of tougher and somewhat easier days to break things up with some nice forest and meadow sections. The reward is some amazing scenery in a relatively unspoilt part of the world. The whole trip was very well organised and accommodation at Villa Hermani was very clean and comfortable, with friendly hosts and great food. The mountain huts were a good experience but be prepared for very basic toilet and sanitary facilities.
