L'itinerario è un noto trekking che unisce 6 rifugi all'interno del Parco delle Alpi Marittime.

Percorre sentieri in quota, vecchie strade militari in pietra, affianca laghi alpini e passando per colli anche a quote di quasi 3000 metri unisce valloni paralleli, con partenza da Sant'Anna di Valdieri e termina a San Giacomo di Entraque.

È un itinerario in linea, chiaramente si può percorrere in entrambe i sensi.

Esistono molti siti internet che lo propongono, anche il sito ufficiale del Parco.

Start at the Coffee Cat coffee shop at Peak Lenin’s Base camp follow the trail to Advanced Base Camp (camp 1). From there, follow the trail to the base of Yuhkin Peak and ascend to the summit via the trail. 
 

cut down the face of the peak back towards the start of the climb. Then follow the trail back to base camp.

The route includes several different trails but is a straightforward linkup. Crystal Mountain is a popular ski resort but also includes some beautiful trails and when combined create a logical circumnavigation of the ridge lines surrounding Crystal Mountain Boulevard. Over the years I have seen many trail runners complete this loop on strava and it is an excellent training run. I think it would be interesting for this popular training loop to be turned into an FKT and see how fast this challenging route can be completed in.
