From Azuga I followed Grecului valley to Saua la Cleste then another
trail towards Poiana Izvoarelor , Pichetu Rosu and Prepeleag then ending
at the Bucsoiu and Omu peaks . Because I didn't allocate well my time
(it took me six hours from the Azuga rail station to Omu summit) and I had
a train to catch in Busteni the descent of the Cerbului valley towards
Busteni was the fastest in my life - it took me only 2hr 24min non-stop
from the Omu chalet down to the point where the trail leaves the forest
and meets the Cerbului valley, some 2.5km from the National Road.
