Again a three-day trip. The first day we went by car up to "La Cariera"
(near Porumbacu) then on foot up to Negoiu Chalet . Second day we left
the chalet with plans to reach Caltun Lake by Piatra Pranzului and
Strunga Ciobanului but the enthuziasm has waned after Strunga Ciobanului
so we returned to the chalet. In the third day the others descended to the
car and I crossed the mountain on the itinerary Negoiu Chalet - Serbota
Peak - Custura Saratii - Negoiu Summit - Caltun Lake - Piscu Negru
.
