As Rohtang pass is a gateway to Lahaul so Kunzum pass (4590 m) is the gateway to Spiti from Kulu & Lahaul. After crossing Rohtang pass and driving 20kms, one has to turn right from Gramphoo. While going to this pass, the panoramic view of Bara-Sigri glacier (second longest glacier in the world) is enthrilling and inspiring.
There is a temple at the top of this pass dedicated to goddess Durga. After seeing this pass one can drive to Batal for a night stay in the Rest House. The view from the top is breathtaking. On one side is the Spiti valley and to the other are numerous C.B.(Chandra-Bhaga ) range peaks. On way back from Gramphoo one can either return to Manali (71kms.) or can go to Leh via Keylong , Darcha, Baralacha la, Sarchu, Tanglang la by road. From Tandi (8kms. short of Keylong) one can also drive to Pangi valley along the Chenab river to Udaipur, Trilokinath and Tindi and thereafter by trekking to Killar. From Killar to Chamba/Dalhousie/Delhi or to Kishtwar- Jammu-Delhi.
