On the Sarchu to Manali bike route along the Manali–Leh Highway, riders mainly encounter Baralacha La Pass and the Atal Tunnel. After leaving Sarchu, the road climbs gradually through Zingzing Bar and passes the beautiful Suraj Tal lake, then reaches Baralacha La Pass (about 4,890 m / 16,040 ft), which is the highest point on this stretch and often has snow and cold winds. After crossing the pass, the road descends toward Bharatpur, Jispa, and Keylong in the Lahaul valley. From Keylong, you continue to Sissu, where you enter the Atal Tunnel, a 9.02-km-long tunnel that bypasses the old Rohtang Pass and takes you directly to the Manali side, making the journey faster and safer, especially during bad weather.
