There are two possibilities of crossing from Yalung valley to Gunsa Valley. The more frequently used, much easier and much lower route crosses three passes and another one - which requires experience and equipment in the presence of snow crosses Lapsang La at 5156 m. The problem with crossing Lapsang La is luck of trail - one should follow rocky cairns but it is not easy to find them. Sometimes it requires to climb big builders and the trail is constantly under threat of stone falls or even avalanches from the nearby hanging glacier. |
